Windows 7: BSOD after taking in PC to repair shop

03 Oct 2011   #41

Windows 7 Professional x64

I turned on the ACPI 2.0 option in BIOS, logged into Windows and got a BSOD...

I am getting really frustrated now. have no idea what's wrong with my PC!

I wonder if it could be a problem between the mobo and the harddisk. Not the HD itself, but the way data is transferred to and from the CPU and memory. Perhaps large transfers somehow error out and keep causing the random BSODs.
Was the BIOS ever properly reset to its default values? If not, I would urge you to try that before starting to manipulate any settings. (I would think that resetting to defaults also turns on ACPI 2.0 which you found to have been disabled for some reason.)
It might be remotely possible that the videocard has a hardware fault as well, maybe it's worth trying another card in this PC for a while.

I've cleared the CMOS before and also restored BIOS to default.

I've also tested a different video card and hard drive in my PC, still got BSOD.

At this point i'm thinking it might be the Motherboard or Power Supply...but WhoCrashed keeps saying that it's a driver thats causing the problem, not hardware.

Have you run Prime95 yet? If so, what were the results? If not, be sure to run all three tests. Again, the link: Hardware - Stress Test With Prime95

Forget what WhoCrashed says about this being a driver problem; it is most certainly not. I'd think that the problem has to be with the RAM, CPU, or motherboard. Remove one of the sticks of RAM and run on the remaining 4GB. Do whatever is in your power to do to trigger a BSOD, and if you get one, swap out that 4GB stick for the other one and repeat. You might also try running Memtest86 overnight on each of the 4GB sticks.

I agree with Jonathan_King, looks like a hardware caused issue.

Follow the BSOD posting instructions and post the mini dump files and the other requested files.
These can be compared to your previous crash files and might give us an idea of where to go next.

Let us know the results from Jonathan's recommendations.

Hi guys, sorry I haven't posted in the past few days, busy at school.

I tried each stick individually and my PC still crashes.

I'll be uploading the BSOD minidump files later today.

I also want to add that whenever I try to install World of Warcraft using the game dvd, my PC crashes...

Should I try switching the power supply?

Switching the power supply doesn't require any setting changes right?

I tried Memtest again today....came up with a ton of errors.

I don't get it, 2 weeks ago I ran it for 10+ hours and no errors popped up.

Now i'm getting errors?

Have you changed your RAM voltage? Its possible that you need more voltage to the ram for it to be stable.

Debugger says probably caused by pool corruption. So either your memory is corrupt(likely, given your memtest results), driver, or it's some other hardware.

You should ensure that all hardware is at stock specifications and then run Prime for atleast 5 hours. Hardware - Stress Test With Prime95

The exception code is "NTSTATUS) 0xc0000005 - The instruction at 0x%08lx referenced memory at 0x%08lx. The memory could not be %s.

This parameter (0xC0000005) usually means a memory exception (probably a driver)

Increase your Memory voltage by about 0.05 V, then Run RAM - Test with Memtest86+
try to run it overnight.

Also try Using Driver Verifier to identify issues with Drivers
