Solved BSOD after taking in PC to repair shop

[Ferny84]

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!

 

[Corazon]

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.

 

[Ferny84]

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.

Hello,

Have you run Prime95 yet? If so, what were the results? If not, be sure to run all three tests. Again, the link: www.sevenforums.com/tutorials/100352-hardware-stress-test-prime95.html

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.

 

[Ferny84]

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?

 

[Ferny84]

I have uploaded the latest minidump files and permon report.

 

[Ferny84]

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. http://www.sevenforums.com/tutorials/100352-hardware-stress-test-prime95.html?

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 http://www.sevenforums.com/tutorials/105647-ram-test-memtest86.html
try to run it overnight.

When seating RAM modules in their slots, it's important to seat them firmly and properly --

Believe it or not, but I once had a problem with seemingly bad RAM and tons of memtest errors when I realized that I was seating the modules by pressing down on their edges until they clicked into place. Turns out the motherboard was flexing too much under the pressure and the center of the modules wasn't making perfect contact like the edges were.

I ended up pressing my fingers against the motherboard from the other side to stabilize it while seating the RAM and pressing down along the entire length of the module, edge to center to edge.

Any and all memory errors magically disappeared.

So while this might have nothing to do with your scenario, I thought it would be worth mentioning...do doublecheck that your modules are really firmly in place.

Make sure you are testing both the RAM sticks and their slots to determine which one(s) are at fault, then try running without any stick at fault or replacing it.

The steps to check both the sticks and slots are here: RAM - Test with Memtest86+

 

[Jonathan_King]

In addition to the advice given, let me add that Memtest86 is sometimes quirky. You get errors once, then never get them again. You get no errors three times, and on a fourth you get tons. One thing is sure, though, and that is whenever Memtest86 says there are errors, it means it. We have yet to see a false positive, so don't ignore them!

 

[Ferny84]

Alright, reseated my memory and ioncreased the voltage to 1.56v.

Lets see if this helps.

 

[Ferny84]

Still crashed

Should I try setting the voltage to 1.65v?

That what my old memory used:
OCZ DDR3 PC3-10666 Gold Low Voltage Dual Channel - OCZ

 

[Jonathan_King]

I wouldn't increase the RAM voltage more; I'd suspect the stick(s?) are plain old "faulty". Try returning your memory if you can, or purchase some new stuff.

 

[Ferny84]

But I just bought them in August.

 

[serpentracer]

leave one of the sticks installed. try them all. see if it crashes.

I suspect you either have the wrong speed or the memory you have the bios is having issues with it.

I've bought my share of memory that just wouldn't work right even though it's specs matched my motherboard's specs.

 

[Jonathan_King]

But I just bought them in August.

Good...still under warranty then!

 

[Ferny84]

I tested my memory again and it shows no problems...this is getting bad.

I don't understand how it could fail Memtest then pass.
