BSOD ntoskrnl.exe (nt+0x7CC40) pciidex.sys (PCIIDEX+0x118B) win7x64

So this is the first desktop I have built and seems like I have a pretty standard build. I just build this about a week ago and ever since the first day after installing windows 7 64 bit I get random Blue screen crashes. All of the hardware is brand new. I have re-installed windows a few times now and this most recent install I left out the graphics card and the wireless card. Still getting BSOD. I ran a memtest86 for over 9 hours with about 7 or 8 passes with no errors. Also did a check disk with no errors. I've read many places here that it's probably a driver issue so I went into the device manager and manually made windows search so that everything is updated. Still BSOD. I followed the BSOD posting instructions and have attached my files and hardware specs. Hoping you guys see something in these files, thanks!

Out of my 5 dumps, 4 say ntoskrnl.exe and the other has pciidex.sys as the culprit when I ran WhoCrashed.

Maybe I need different mobo drivers?
Is it possible i just have cheap RAM that can't support 64 bit?
Was also thinking possibly this wireless keyboard?


Windows 7 Home Premium 64 bit
Intel Core i3-2100, 3.10 GHz, 3MB Cache, LGA1155
Gigabyte H61M-S2-B3 Intel H61/rev.1.0
2x4GB DDR3 Patriot PC3-10666 1333MHz
Seagate 1TB Serial ATA HD 5900/32MB/SATA - 3G
Diablotek Elite ATX Mid Twoer w/450 Watt PS
Logitech wireless keyboard
Standard Dell Laser Mouse

Update:
So yesterday afternoon I took out one of the memory sticks and am just running on one 4GB stick. The system has now been up for about 12 hours without a blue screen so it seems to have stabilized. It's never lasted for more than about 3 hours before. Not sure if maybe my memory is configured in the BIOS wrong or my mobo can't handle 8gb? Or just a coincidence so far.

Could be a bad stick, incompatible memory sticks (are they the same brand/frequency/bought at the same time?), or not enough voltage being supplied by the motherboard's DRAM voltage setting. Let us know if you need further assistance addressing your problem. :)

Yes they are the same brand/frequency/bought at the same time. Wonder if my board just might not support 8gb of this RAM. Either way i'm running fine on 4gb for now. This can be closed, thanks!

Thank you for posting back. Glad reducing to 4GB worked for you. If you find that 8GB is supposed to work for the motherboard, we would be happy to assist you determining why it is not working.
