I'm posting this from work, so I don't have the memory dumps from the BSODs but I will attempt to post them when I get home. I'm hoping someone will have seen a similar problem and now how to resolve it.
Up until 5 days ago I had XP64 installed on my primary system. It worked perfectly, except once every two or three months a JMRAID.SYS driver
would blue screen the system. I then installed an MSDN copy of Windows 7 Home Premium in trial mode, but it immediately began blue screening. Here are the specs:
Intel Q6600 @ 2.4 GHz
3GB DDR2 667
XFX Radeon 5750 1GB
Western Digital 7200RPM 640GB SATA II
NEC 16X DVD-RW
The symptoms are that 1-2 hours after booting the system it will crash with a bugcheck B4 or 116 in drivers
NTOSKRNL.SYS or DGXKRNL.SYS. The other symptom is that SiSoft Sandra will lock up in the GPGPU Encryption Test, but only when preceding it with other tests in burn-in mode. Running the test immediately after boot will work fine. "Lock up" means that the system freezes; even the mouse won't move. Upon reboot there are no events in event viewer that correspond with the time of lockup. Sisoft leaves a blank log, so there's no telling what part of the test is locking the system up.
What I've tried-
- Reinstalling Windows 7
- Swapping in an Nvidia 8800GT - this works fine, but is a very dated card.
- Driver verifier - detected bad behavior in AVG so installed Avast
- Running with only 2GB (2x1GB instead of 3x1GB)
- Trying the Radeon in a different system. Got a VPU recover error, but I was trying to run it on a system with 1.5GB of RAM.
- Monitoring temps. The CPU tops out at around 71C (but not during the GPU Encryption test) and the video card at 66C.
- Blowing the dust out of the video card (there was some but not a whole lot.)
- Installing an older version of the Catalyst drivers (11.3)
- Trying a different monitor
I wanted to try Windows 7 before buying it, and it looks like that was a good idea...
I'll try to force a crash by playing a video game and post the memory dump once I get a chance to get home. The old dumps have been wiped out by reinstalls of Windows 7.
