I have been getting random blue screens for a couple weeks and am having problems tracking down the source. Windows 7 Home Premium 64 Bit Asus M4N75TD Mobo Athlon II X4 635 CPU 8 GB RAM OCZ & Crucial Galaxy GTX 460 x2 in SLI 1000 watt PSU Noctua NH-D14 cpu cooler Kaspersky Internet Security Suite I listed everything I think is relevant for system, this is a new computer build as of a month ago and for two weeks I did not have a problem. I know it could be a lot of different thing with new build but just wanted to try and troubleshoot this through the dumps and such to see if I can get a culprit. I ran memtest and got a couple hours of good results, 2 passes with OCZ memory. I do have another set of crucial memory that5 I will switch out as soon as I am done posting this to remove that as a problem. I ran driver verifier and did not receive a bsod with that running for all non microsoft drivers. BSOD's have been 7F FC D1 OA but all have ntkrnlmp.exe as faulting problems in memory dumps. I have read dumps using Windows Debugging tools but cannot find any source other then the exe that it refers to but many say this is probably not the cause. I do load a lot of various software as I review computer products but have never had the multitude of problems with BSOD's and not being able to pinpoint a single driver or hardware that I installed like this. I have attached memory dump files in winrar. I have included four memory dumps, the others were erased while doing some troubleshooting last week.
