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.
