1st off about 4 months back i had a nvidia gtx 560 ti which burnt out *stopped working entirely, and i had a stick of my corsair vengeance go bad as well *tested with memtest86 and all kinds of other diagnosis tools indicated 1 bad stick..i rma'd those and sold theem to a friend and recently bought a xfx Hd7970 and 16gb of corsair dominator...computer started off rrunning good no Bsods, no crashes. until this morning...installed Planet side 2 logged in played for 5 minutes and the computer rebooted. i checked my temps and i was getting a faulty temp from hwmonitor so i went into my bios to see my mobo temps everything looked nice a cool...discarded changes and exited the bios and it went straight into a minidump Bsod...i currently have nirsoft bluescreeen viewer on and 2 of the errors are highlighted pink Hal.dll+12a3b and ntoskrnl.exe+18c633 ive cleaned and repaired my registry, repaired my windows, updated all drivers clean. please if anyone can help with this post i'll be your bestfriend for life..
