BSOD at random - WerFault and Freshly Booted Windows during the day..

Windows 7 - x64 - SP1 - TechNet Genuine - What is the age of system (hardware), everything bar two hard drives <6 months old. - What is the age of OS installation (have you re-installed the OS?) - 3 months

Issue is a blue screen on an intermittent basis of thing such as LT_ZERO_AT_SYSTEM_SERVICE etc.

Thanks for your help

It smells like hardware failure, but we'll look at software just in case. Remember, if you are overclocking your PC any, reset to factory defaults. I saw in one of the crashes what looks to be a corrupted CPU register. We'll confirm though.

Turn on Driver Verifier. For checks to use, select all except IRP Logging, Low Resource Sim, and Force Pending I/O Requests. Restart after everything is finished. If you get reboot loop, go into Safe Mode (F8) and turn DV off. Send us new crashdumps.

Since I think this may be hardware, perform the following:


RAM: Memtest86+ - 7+ passes
CPU: Prime95 - Torture Test; Large FFTs; overnight (9+ hours)

Also, please provide us temps/voltages using HWInfo with Sensors only option checked. Log two 30-minute instances: one for idle, and one for high load. If you can crash system while logging, that's better.
