Windows crashes randomly (no blue screen, just locks)

[joesklar]

Hi,

I have recently upgraded my PC, and I'm running into a few problems with it.
Specification is as follows:

CPU: 3930K stock clock speed
Motherboard: P9X79 Pro
RAM: 16GB Vengeance DDR3 (8GBx2 - 1333MHz)
PSU: Corsair Pro Series HX1050
GPU: Zotac GeForce GTX 780Ti x2 SLI

Heatsink: bequiet! Dark Rock Pro 3

------------------------------------------------------------------------------------------------------------

The reason for the upgrade is that the original cooling loop pump had failed and so the CPU an previous GPUs were overheating.

Ever since upgrading the parts, the system will perform to spec but lock up at any given time.
CPU temps are 30 degrees C at idle and 55-60 under load.
GPUs never reach higher than 65 degrees C

Crashing will occur consistently when running benchmarking software or attempting to open GeForce Experience software.
Crashing also occurs when the PC is unattended and idle.

I don't think the components are overheating but the symptoms would suggest that.
Windows 7 has been reinstalled on a 64GB SSD.
I have a 1TB storage drive and an additional 240GB SDD configured for hotswap.

I'm at a loss now, so any suggestions would be greatly appreciated.

If anyone was curious as to why the CPU is at stock speed, it's purely for diagnostic purposes. I fully intend to overclock CPU/GPUs ad RAM once I have the PC working.

Thanks again for any input.

i dont think windows 8 works on desktops, try with a windows 7.

It's not Windows 8, that's why it's in the 7 forum.:lol:

Have you tried resetting the CMOS?
Are you running the latest version of the BIOS?
