Hard Lock up while graphic-intense load?

[skimyy]

Guys I need serious help.

Just spent about $1k for a new build and the system hard locks while gaming. Not even a BSOD.
Also just watched some youtube on full screen and experienced a lock.

Its just so weird as there are times where I play Crysis 3 for 2hrs+ without a lock, and then other times I watch a 5 minute youtube video only to get a hard lock...

I am at a COMPLETE loss here.

I updated GPU drivers, etc. Heating is definitely not a problem as CPU has yet to pass 45 degrees. (Have Hyper 212 cooler) GPU has never passed 60 degrees.

What could be the problem here?

My Spec:

MOBO : GIGABYTE GA-990FXA-UD3
PSU: Seasonic X750 Gold
CPU: AMD FX8350 Vishera
RAM: Gskill Ripjaws 1600mhz 8gb.
SSD: OCZ Vertex 4 128gb
HDD: Seagate Barracuda 1TB
GPU: Sapphire 7950

It sounds like a software problem

what operating system are you using?

Windows 7 64 Bit Ultimate.

run dxdiag and see if there are any errors

also check in BIOS the timings and voltages of your RAM . If you havent done it already you are probably going to need to apply an XMP profile

No errors on Dxdiag.

Ram timings and voltages are standard and what they should be for Gskill Ripjaws.

Could a bad hard drive cause this?

K guys. Solved the problem.

I set the minimum processor state to 100% from 5% and hasn't been freezing/hard locking ever since.

Edit: From the Power Options.
