Hi guys, I have the current setup: AMD Athlon II X4 635 2.9Ghz processor. 2GB GSkill 1333Mhz RAM. (Had 2*2, have claimed 1 for replacement). 1TB HDD. (Had 2*1TB, I have claimed 1 for replacement). Gigabyte 785GMT USB 3.0 Mobo. MSI R5770 Hawk GPU. Corsair VX450 PSU. BSOD errors when viewed in BlueScreenView show the files as ntoskrnl.exe and win32k.sys. The strings are SYSTEM_SERVICE_EXCEPTION, KMODE_EXCEPTION, NTFS_FILE_SYSTEM, BAD_POOL_HEADER and IRQL_NOT_LESS_OR_EQUAL. I had 2*2GB Gskill RAM, one of them was corrupt which I have sent for replacement. The other one which I am using has no errors, I checked with Memtest for 10 passes. The 1TB HDD I am using is also new, a fortnight old. Have attached the perfmon report and a few BSOD dumps too.
