Initially it booted 'ok' - a bit slow and unhappy, but it got there. I installed the drivers for the new graphics card. It crashed. I rebooted and some warnings came up saying that some dll's weren't installed properly. Then, after a minute or two; bluescreen. This happened again the next time I rebooted. <br /> <br /> The following reboot only got as far as the Windows loading screen - blue screen and reboot as soon as it reached a certain point - the same each time, so I knew it had to be something to do with a particular boot file. So I rebooted in Safe Mode and saw that it hung on MUP.sys<br /> <br /> I tried using the Repair function from the Windows disc, but it kept coming up with error messages. In hindsight I think this might have been because I'd left the 'keylock' button on the front panel of the PC switched on, but needless to say I tried another approach after this:<br /> <br /> <br /> Luckily I fixed it pretty quickly - this is what I did:<br /> <br /> Set BIOS to boot CD first<br /> Ran windows XP from startup disc<br /> Installed Windows onto one of my data drives that had enough space<br /> (I didn't reformat it - all my data stayed on the disk - I just made it bootable)<br /> To do this make sure, when it comes up with all the visible partitions and file systems, you select 'Leave current file system' and install without reformatting (or you'll lose all your data).<br /> <br /> Once installed, I set BIOS to boot to the data drive first.<br /> It booted ok and former system drive showed up as data drive (d:\).<br /> I copied 'MUP.sys' from c:\windows\system32\drivers to d:\windows\system32\drivers<br /> I rebooted and reset BIOS to boot to the original system drive.<br /> I opted to boot in Safe Mode again.<br /> It still hung on MUP.sys for quite a long time, but eventually it did let me boot into safe mode.<br /> Once in safe mode I ran Checkdisk on the now D:\ drive (the thorough version - took about an hour) - it fixed a bunch of errors and restored some bad sectors on the drive. <br /> I then installed Quad Registry Cleaner, which I had downloaded from another computer.<br /> This fixed all the registry errors caused by yanking out PCI cards, and it rearranged my bootlog to correspond to the current hardware configuration. <br /> I rebooted and it loaded in Normal mode no problem at all.<br /> I then reinstalled all of my hardware one by one, rebooting each time.<br /> Back to normal! yesss!<br /> text/html 2009-07-14T19:41:04-05:00 Javier Santillanes http://www.hardwareanalysis.com/content/topic/31874/?o=760#562104 UPDATED FIXES IN EASY ORDER:<br /> <br /> &gt;&gt;· Change IDE, Serial ATA cables. (very possible)<br /> &gt;&gt;· Remove any USB devices attach. (very possible)<br /> &gt;&gt;· Reset ESCD in your BIOS. (very possible)<br /> &gt;&gt;· Disable ACPI in the power management section of the BIOS (very possible)<br /> &gt;&gt;· Reset BIOS (could'nt hurt)<br /> &gt;&gt;· Disable MUP in recovery console. (MUP is not the problem, but try it if you want to, possible problems &gt;&gt;in the future, not fixing the real issue)<br /> &gt;&gt;· Run chkdsk /p in recovery console. (this assumes that your hard drive could be bad)<br /> &gt;&gt;· Move memory to another slot. (querky, not fixing the real problem)<br /> &gt;&gt;· Move PCI cards out or in a different slot. (same as above)<br /> &gt;&gt;· Bad CPU’s (most likely not, CPU's have a very low fault percentage)<br /> <br /> Bad PSU <br /> Worked for me after trying everything, the clue unpluged cd/dvd/ change memory and surprisely windows start but before logon reboot again. I tryed with other PSU and PC works perfect<br /> <br /> <br /> <br /> text/html 2009-07-13T04:51:36-05:00 Waleed Abo Zead http://www.hardwareanalysis.com/content/topic/31874/?o=760#562058 Here is The Solution :<br /> Use Partation Magic 8 From Dos(Hirens's CD)<br /> it will allow you to access for your hard disk and format all your hard disk then start to setup new OS<br /> text/html 2009-06-11T13:06:21-05:00 Alphi Alphi http://www.hardwareanalysis.com/content/topic/31874/?o=760#560252 I also had this problem today.. <br /> it just occurred out of the blue.. so I thought one of my hard disks had died.<br /> <br /> the affected PC was being used for storage so it had 5 hard disks installed.<br /> <br /> so I began unplugging drives and testing the machine to see if it would boot up<br /> and sure enough it did.. <br /> <br /> then I noticed my CDRom drive wasnt showing up.. so I unplugged the hard disk on the same power rail as it and the CDRom worked..<br /> <br /> it then gave me the idea to go back to the disk which I thought was a dud and plug it back in while removing the power to other drives on that power rail and it booted up no dramas at all..<br /> <br /> my conclusion...<br /> <br /> too many devices drawing power from the PSU reduces the voltage to some devices so that they no longer work properly causing windows to hang once it spins up all the devices after MUP.SYS<br /> <br /> ill just have to live with less hard disks inside my pc and use my WELLAND Externaly powered drive bay for the rest.<br /> <br /> <br /> Hope this helps anyone else with the same problem.<br /> <br /> <br /> Oh and if your wondering how my machine could have possibly stopped working after running fine for several years with no added hardware.....<br /> <br /> I have 2 theories..<br /> <br /> 1) the fans as they gather dust actually slow down so the BIOS runs them faster thus drawing more electricity.<br /> 2) the PSU might be failing/getting old so it can no longer deliver the same amount of power.<br /> <br /> <br /> or a combination of both..<br /> <br /> just my 2c<br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> text/html 2009-03-26T09:59:15-05:00 lice icoffee http://www.hardwareanalysis.com/content/topic/31874/?o=760#555614 you can use Registry Easy clean your registry,this tool work for me.remove the windows errors,useless files.solve your computer crash problem.<br /> <a class="ext" href="/action/r/http://www.keep-pc-clean.com/" target="_blank">http://www.keep-pc-clean.com/</a> text/html 2009-03-25T23:52:56-05:00 Culpeper http://www.hardwareanalysis.com/content/topic/31874/?o=760#555573 More on this topic.<br /> <br /> PROBLEM: WinXP will not boot into Safe Mode of any type after mup.sys shows on screen. Safe Mode Fixer utility software does not correct problem.<br /> <br /> I ran bootlog and you wouldn't believe the number of driver not loaded lines I was seeing. The last good load was &quot;giveio.sys&quot;, which was just after &quot;mup.sys&quot;. Giveio.sys is related to the Speedfan utility software and noticed that &quot;speedfan.sys&quot; was also loaded just prior to &quot;mup.sys&quot;. I had already uninstalled Speedfan so I searched the registry and removed the legacy entries for &quot;speedfan&quot; and &quot;giveio&quot;. Also went into System32 folder and renamed &quot;giveio.sys&quot; and &quot;speedfan.sys&quot; and a ran a new bootlog. That got rid of probably hundreds of the original bootlog dirvers not loading and I ended up with the following much much much smaller bootlog file but with the same problem mentioned above:<br /> <br

<br /> Uninstalled SP3 because my video drivers were installed after that Windows update. <br /> <br /> Reboot<br /> <br /> Installed video drivers<br /> <br /> Reboot<br /> <br /> Reboot<br /> <br /> F8<br /> <br /> Enable boot logging<br /> <br /> Viewed new boot log. Same as the old one.<br /> <br /> Ran Safe Mode Fixer utility (just for the heck of it)<br /> <br /> Reboot<br /> <br /> F8<br /> <br /> Safe Mode<br /> <br /> Worked.<br /> <br /> I would not recommend installing Speedfan, at least the beta versions, because it doesn't actually uninstall thoroughly and may cause conflicts with motherboard drivers trying to load over and over again during the boot process. Also, I don't plan on reinstalling WinXP SP3 just to see if I can recreate the problem again. I can remember seeing a flurry of SP2 mup.sys issues when that version came out.<br /> <br /> You know, the whole mup.sys fiasco is ridiculous. I place the whole thing at the feet of people that always claim, &quot;nothing wrong with my code, must be hardware.&quot; The hardware being the cause is moot. The OS should be able to detect the problem and inform the user. Not ifs, ands, or buts.<br /> <br /> Gread thread. It took me about 4 hours to get through the whole thing while multi-tasking at work today. I found it educational and gave me a general idea where to start rather than go after it with a knife and stab it over a thousand times. Also, to the brick and mortar techs that recommend reformat and reinstall OS is translated to your own billable hours. <br /> <br /> text/html 2009-03-23T20:51:26-05:00 E P http://www.hardwareanalysis.com/content/topic/31874/?o=760#555419 I've seen this twice now.

Don't worry if the test takes sime time - I had one take 4 hours and find thousands of errors, Also make sure that the BIOS settings enable the self monitoring - SMART - on the hard drive (if you can find it!) as this will tell you if the drive is failing, by giving a message during boot up.<img src="/images/smilies/smile2.gif" width="14" height="14" border="0" alt=":(" title=":("><br /> <br /> A friend recently had his PC refuse to boot because of a virus. I killed the virus with a bootable Linux rescue CD - there are now several of these from good antivirus sites, like Trend, Kaspersky and Avira (you have to create these CDs with another PC, of course). It is possible that you have the same problem and if so, you must remove the virus before a Windows repair is possible! The system I fixed also had a rootkit installed, so make sure you have an 'industrial strength' antivirus/antispyware package installed. If the virus is difficult to remove, it may have damaged critical Windows files - if so, a Repair install will be needed anyway.<br /> <br /> Nick Law text/html 2009-01-26T21:11:07-05:00 Kyle Hoskinson http://www.hardwareanalysis.com/content/topic/31874/?o=760#552227 Ive read through all 39 pages and have tested everything I am capable of.<br /> <br /> Im not familiar with the computer completely as it is a work computer I never dealt with. It does have an OEM Windows XP home edition. 128 MB RAM AMD ATHLON 1700. <br /> <br /> The computer was moved from one location to another, no hardware changes just a location change. After the move the computer will not load past the windows load screen. It will stay black. I started it in safe mode and it doesnt load past the mup.sys file.<br /> <br /> Ive tried to reboot with a windows xp disk with service pack 1 and service pack 2. When I try to reinstall it, it can not locate another version of windows xp or a drive to install it on. When I try to repair the install that is already on it, the computer freezes and doesnt load anything. If I unplug my hd windows will tell me it cant locate a hard drive. If i leave it plugged in it just keeps looking for it to install on it.<br /> <br /> Ive unplugged everything in my computer, except for the hard drive and it still will not load, I tried this while restarting it in safe mode, normal, last known, and with c prompt. It did not work. I replaced the IDE cable to the hd and that didnt help. Ive changed every setting in my BIOS mentioned and had no results. I have reset them back to defaults as well. Also, I have switched our ram sticks, cleaned them, tried one at a time and in different slots. That didnt net any results either. I have cleaned all heads and pins on the computer as it is very and and has alot of dust in it. That didnt help. <br /> <br /> I have removed all PCI items and unplugged all USB items. I have 2 things plugged into it currently and that is a monitor and a keyboard with the ps/2 connection. I have tried it with a usb keyboard and there is no change in results. I have let it set for 60 minutes trying to boot up in safe mode and normally. I have also waited 60 minutes each for windows to try and repair itself, but it freezes up as I said earlier. When I waited 60 minutes for it to reinstall, windows never found a previous version so it never initiated the install. <br /> <br /> I have tried different power outlets incase it wasnt receiving enough power, that didnt help. I checked my cpu temperature to see if it is over heating and that isnt the case. Also, I tried to upgrade to windows xp professional and it wont allow me to do that either. Same thing as before with my sp1 and sp2 attempts. <br /> <br /> <br /> Unplugging the battery from the motherboard did not post any results either. With all the steps mentioned previously. <br /> <br /> If I have missed any other things to try, let me know. I might have tried them and forgot to mention it as I have spent quite some time on this. Any other ideas would be great also. text/html 2009-01-17T05:30:35-05:00 Bry McG http://www.hardwareanalysis.com/content/topic/31874/?o=760#551505 I couldn't edit my post so posting my update here.<br /> <br /> I kept working away on my computer, restarting trying chkdsk, trying recovery console and also reapairing my installation using WIN XP Cd. I finally got a blue screen of death instead of just hanging. I copied the code down and searched it in Google and nothing came up for it (0xC0000006, 0x80696C12, 0xBACC36E4, 0xBACC33E0) - how can an error code exsist but not be contained on the microsoft database?. So after trying everything i came across i gave this a go (How to recover from a corrupted registry that prevents Windows XP from starting):<br /> <br /> <a class="ext" href="/action/r/http://support.microsoft.com/default.aspx?scid=kb;EN-US;307545" target="_blank">http://support.microsoft.com/default.aspx?scid=kb;EN-US;307545</a><br /> <br /> I went through Part 1 - steps 1 through 6:<br /> <br /> Insert the Windows XP startup disk into the floppy disk drive, or insert the Windows XP CD-ROM into the CD-ROM drive, and then restart the computer. <br /> Click to select any options that are required to start the computer from the CD-ROM drive if you are prompted to do so. <br /> When the &quot;Welcome to Setup&quot; screen appears, press R to start the Recovery Console. <br /> If you have a dual-boot or multiple-boot computer, select the installation that you want to access from the Recovery Console. <br /> When you are prompted to do so, type the Administrator password. If the administrator password is blank, just press ENTER.<br /> At the Recovery Console command prompt, type the following lines, pressing ENTER after you type each line:<br /> <br /> md tmp<br /> copy c:\windows\system32\config\system c:\windows\tmp\system.bak<br /> copy c:\windows\system32\config\software c:\windows\tmp\software.bak<br /> copy c:\windows\system32\config\sam c:\windows\tmp\sam.bak<br /> copy c:\windows\system32\config\security c:\windows\tmp\security.bak<br /> copy c:\windows\system32\config\default c:\windows\tmp\default.bak<br /> <br /> delete c:\windows\system32\config\system<br /> delete c:\windows\system32\config\software<br /> delete c:\windows\system32\config\sam<br /> delete c:\windows\system32\config\security<br /> delete c:\windows\system32\config\default<br /> <br /> copy c:\windows\repair\system c:\windows\system32\config\system<br /> copy c:\windows\repair\software c:\windows\system32\config\software<br /> copy c:\windows\repair\sam c:\windows\system32\config\sam<br /> copy c:\windows\repair\security c:\windows\system32\config\security<br /> copy c:\windows\repair\default c:\windows\system32\config\default<br /> <br /> Type exit to quit Recovery Console. Your computer will restart.<br /> <br /> The only problem was when i first typed md tmp it said access denied(C:\md tmp). I managed to hoak and get around this by making sure i had C:\windows&gt;md tmp. <br /> <br /> After i restarted it loaded chkdsk, everything passed and it loaded to windows. Windows was different, it had nothing in the same place as i had it, like shortcuts gone, some programs missing, my documents was blank had to hoak around to get to my original documents, dunno if this was because of my repair or my copying and deleting those windows files. I immediately hooked up my external and started backing up critical files for it to freeze on me once again. So i had to hard start and boot up, loaded windows without a problem and i looked up device manager, it has flagged(yellow question marks):<br /> <br /> WAN Miniport (IP) - Packet Scheduler Miniport<br /> Ethernet Controller<br /> Multimedia Audio Controller<br /> PCI Device<br /> SM Bus Controller<br /> Video Controller (VGA Compatible)<br /> <br /> After i am finished backing up my 400 GB's i am going to try and system restore point to see if it resolves my yellow flags, then going to do a clean install.<br /> <br /> Loads of people are encountering this problem, there are plenty of fixes but NO solutions and NO causes to why this happens. My system was working fine then not working and i was left with no firm solutions - just scouring through countless pages. Will post up my results after a system restore has taken place and also again after a clean install.<br /> <br /> Thanks to everyone posting on this forum with their specific solutions, i cant say enough now that i am backing up my data. Special thanks to Nick Law for his continuous and flawless step by step instructions, and MERC for simplifying bare bones kit. text/html 2009-01-16T15:37:56-05:00 Bry McG http://www.hardwareanalysis.com/content/topic/31874/?o=760#551418 I have read many posts in this forum and tried out everything i came across to try and solve this nightmare. Nobodys problem matches mine exactly so i will post it up and hope someone has a few more tips for me, any help is appreciated greatly.<br /> <br /> I am running a <a target="_blank" href="/action/r/http://www.dell.com/">Dell</a> dimension, core 2 duo 2.66Ghz, 2GB ram, Nvidia 256mb, 2 optical drives plus 500 Gb harddrive, 2/3 years old, Windows MCE 2005 - all standard from dell. About a week ago the computer froze while playing NFS underground, had to push and hold the power button to shut off. Wouldn't boot normally, tried safe mode with command prompt and it let me in. I ran chkdsk /p (said some errors were detected), then i ran chkdsk /r and it said something to this effect: It is in use by another program can't lock, do u want to schedule chkdsk for the next time you restart - i said yes. Restarted, chkdsk ran the 3 stages and windows loaded. I thought it was a close call so i started backing up.<br /> <br /> Then 2 nights ago left my computer on playing music and when i came back, wiggled the mouse and the system froze again. So restarted, tried all the boot options like safe modes and last known config settings, noting worked (It would hang on mup.sys) the windows logo comes up and the loading bar still moves but my system goes quiet and the harddrive isn't running.<br /> <br /> So i boot up, access Dell's very handy self diagnostic that is a utility on a piece of the harddrive. Ran the extended tests everything passed, ran the short test everything passed, ran the symptom tree tests (everyone!) and they all showed passed - so it was ruling out hardware issues.<br /> <br /> Next to try was the Windows MCE Cd, it booted fine, went into recovery console, chkdsk /p ran and said few errors on drive, so i ran chkdsk /r and it loads up to 50, jumps to 75% and then back down to 50% and my computer just stays like this even though the loading light is flashing on my computer. So i restarted, tried various things like fixboot, disabling mup.sys, disabling everything from bios accept what i need running (bare bones), enabled debugging mode, enabling boot logging, enable vga mode, disable automatic restart on system failure from my advanced start up menu, still to no avail. I have one other option called Directory services Restore mode (windows domain controllers only) i havent tried. I also booted from Win MCE Cd and went to repair the installation, it repaired it, restarted and it still hung on the windows screen!<br /> <br /> One thing mentioned on mine that others havent mentioned is that when i access bios options and go to Event log, i have a POST Keyboard Error with the dates that crashed my computer both times and it keeps recording the problem everytime my system freezes and i do a hard restart. I also disconnected the keyboard and disabled all usb's from BIOS and let my computer load with no keyboard or mouse, still hangs on the windows XP loading screen.<br /> I run ZoneAlarm and AVG Pro with automatic updates on my computer and on my virtual computer, any downloading i download to virtual, scan and move across - i haven't downloaded anything or moved across anything in over a week so its slim i got hit with a virus.<br /> I just took out the cmos battery from harddrive, rebooted and it said system voltage low! Does that mean the battery is shafted?. It let me continue but got stuck booting safe mode at the same stage. My system also didnt load mup.sys so does that mean i didnt leave the battery out long enough, around 10mins?<br /> I have tried to be as specfic as i can - if no idea's are offered i believe i will strap it onto another computer, run chkdsk on it again and suck as much data as i can off it and then looking at a wipe. The only thing i havent ran is the FIXMBR because i dont wanna lose my data if it goes wrong.<br /> <br /> <br /> Thanks for anbodys time and effort to reply to my post!<br /> <br /> text/html 2009-01-11T22:36:22-05:00 finally resolved http://www.hardwareanalysis.com/content/topic/31874/?o=760#551015 Do you even (someone) try my method from previous page? Is working? Is not working? Is not a solution? Do anyone try that? Do anyone read that? Two days to resolve this problem and no one see my two long posts? text/html 2008-12-30T15:15:43-05:00 TamTheBam http://www.hardwareanalysis.com/content/topic/31874/?o=760#550268 <br /> Do people still use this OS?
