I'll start at the beginning.
I recently switched out my graphics card and replaced it with a 2nd hand 275GTX. I should note, i (and the previous owner) have used the card without issues for a fairly long period of time. It was only problems with my monitor loosing signal while playing Modern Warfare 2 and (i think) driver
crashes that caused me to look deeper, and has led to a range of problems. I'm not sure if they were there before, but they have only recently come to surface.
The machine then started to do weird things in games, which I traced back to drivers
with the Event Log. So I finally got around to formatting my PC and starting fresh with drivers and new hardware.
Since then i have been having random BSOD errors on startup. Sometimes i boot and run fine, sometimes i cant get past the Windows loading screen with crashing and other times it will load windows then crash after 5-10secs.
Instantly i thought that it was a GPU problem, so i switched it out with a spare 6600GT i have, and the same thing continues to happen. Sometimes the PC will BSOD before or just after windows startup and other-times i can boot up fine and never notice anything was wrong.
If the machine does crash with a BSOD it will continually loop. Crashing, then restart then load up and BSOD again ect ect. If i turn the whole PC off at the PSU then it has its normal "chance" of loading normally. Trying to boot into Safe mode doesn't seem to help, it simply changes the BSOD error.
If i try to boot normally into windows i get one of two BSOD messages:
If i try to boot into safe mode i usually get this message:
Sometimes randomly i get the message on startup, briefly before it crashes:
I am not 100% that those errors only occur in those circumstances, but that seems to be what i have noticed.
I have tried the following fixes:
- All current windows updates
- Boot into Memtest86+ and run overnight = no errors recorded
- Stress tested CPU with Linpack and Prime95
- Removed all overclocks and reset BIOS
- Updated to latest BIOS version
- Stress tested GPU with Furmark, nothing wrong after over 12 hours
- Running the GPU with the previous 5 driver versions and the current Beta
- Running the GPU with default Windows 7 Drivers
The only thought i have had, could it possibley be a problem with the GPU seating? i have tested it, but at the moment the Motherboard is lying flat and the GPU is not attached to anything.
Im seriously stumped
Any help is really appreciated!
