Title: Thank Goodness For Backups Post by: Phoenix on 2010-08-05, 00:59 I recently ran into some serious trouble with my PC. I started getting BSOD MACHINE_CHECK_EXCEPTION on the way into Windows about a week ago, followed by an immediate reboot. After a few times it would let me in, until last night when it was infinite looping. My "maintenance" drive booted fine though, so it didn't look like a hardware failure. I hooked up my external backup drive, renamed my Windows folder, copied down the one I backed up about 2 months prior, and voila, no more problem. The hard drive shows no physical errors and I'm on a RAID 1 array anyway, so I don't know exactly what happened. I'm supposing the registry or a critical operating system file was damaged somehow by a glitched write operation.
Either way, my backup saved a lot of headaches and potential lost time and after repeated tests everything seems to be working fine. :doom_thumb: Title: Re: Thank Goodness For Backups Post by: ReBoOt on 2010-08-05, 12:37 Backup is a good thing :) the stop code on BSOD helps to find out what's causing the issue, but sometimes it's a pain finding out what's causing the issue, god i hate my job sometimes, but rather have a BSOD than the evil vista/win 7 Black screen of death..
Title: Re: Thank Goodness For Backups Post by: Phoenix on 2010-08-05, 13:37 The problem with this particular BSOD is it rebooted the computer so fast I didn't even have time to record the code. I had to memorize it over a few reboots. I have Windows set to NOT reboot on a stop fault but it was doing it anyway.
If you're curious about the exception itself, the error code was this: Code: MACHINE_CHECK_EXCEPTION Title: Re: Thank Goodness For Backups Post by: Tabun on 2010-08-05, 17:41 Which reminds me.. time to make a backup of the forum.. :]
Title: Re: Thank Goodness For Backups Post by: Angst on 2010-08-05, 19:34 Eww 9c.. Good luck tracking that one down--it generally seems to involve some sort of timing issue..
overheating AMD chips, PSU issues, RAM instability, and failing IDE cables are the short-list of likely culprits. Title: Re: Thank Goodness For Backups Post by: Phoenix on 2010-08-05, 20:52 As I said, replacing the Windows directory with a backup copy fixed the error. It has not reoccurred since. :)
Title: Re: Thank Goodness For Backups Post by: ReBoOt on 2010-08-11, 16:46 ox9c is usually an overheating CPU, or a problem with the CPU, so far i've only had this BSOD once with all the computers i've fixed so far and it was actually an broken CPU, so i find it abit odd that replacing the win dir fixed the problem :) but anything that works is what counts! Maybe one of the cached drivers was the problem, i've seen those go corrupt and cause all kind of weird bsod's
