Hello, For a while now my PC has been randomly crashing and throwing up BSOD's. I've tried all of the steps mentioned in the "Before posting your minidumps, please read this" thread, made sure all drivers are up-to-date, tried other resolutions, and rebuilt several times. Yet I can't seem to get to the bottom of it. PC Build is this: Asus Rampage Formula S775 X48 Intel Chipset PCI-Express DDR2 Motherboard Intel Core 2 Duo E8400 2 x 3.00Ghz 6Mb Cache 1333 FSB Ballistix Tracer PC2-6400 4GB Memory Kit BFG Geforce 9800 GTX 512MB PCI-E Western Digital Caviar SE16 500Gb 16Mb Thermaltake Toughpower 850WATT PSU I've attached the two most recent mini dump files, these ocurred with the following system log errors: Error code 10000050, parameter1 a5aee428, parameter2 00000000, parameter3 bfccc290, parameter4 00000000. Error code 1000007e, parameter1 c0000005, parameter2 bfccc5f0, parameter3 b537762c, parameter4 b5377328. Also it sometimes crashes and throws a BOSD without recording a system error, in these events it's random applications causing the error with no pattern or any reason that I can see, examples: Faulting application avgrsx.exe, version 220.127.116.118, faulting module avgcorex.dll, version 18.104.22.1687, fault address 0x00077478. Fault bucket 1060136963. Faulting application crysis.exe, version 22.214.171.1240, faulting module crysystem.dll, version 126.96.36.1990, fault address 0x00081359. Faulting application iexplore.exe, version 7.0.6000.16827, faulting module mshtml.dll, version 7.0.6000.16825, fault address 0x000d9a92. I was hoping someone could take a look at the mini dump files I have and give me an interpretation, as I don't know how to read them. Any help anyone can provide would be greatly appreciated. Thanks, Matt.
