I've been getting BSODs on my custom-built PC for a couple of months now. They include, but are not limited to, system service fault (exception, maybe? Not sure), IRQL not less or equal to, and page fault in non paged area. The drivers listed as causing the issue include, among others, nVidia/DirectX drivers, usbaudio.sys, and NTFS. The computer will sometimes fail to boot after one of these bluescreens, and I have also had the BIOS freeze on me occasionally. I've taken the steps in the stickied thread as well as the following: -Reformatted my computer entirely -Run HDAT2 on the hard drive (no errors) -Replaced power supply -Swapped graphics cards -Flashed BIOS to newest version -Updated drivers for ALL hardware I cannot currently provide minidumps as my computer just bluescreened and is refusing to turn on. Are there any suggestions as to what might be causing this issue? EDIT: in my BIOS, it's showing my processor idling around 57 Celsius. I have an AMD Phenom II x6. This doesn't seem normal - could this be my culprit?
