My computer keeps freezing. I have:
-Updates my BiOS
-Updated my graphics card drivers.
-Reset BiOS to defaults(IE resetting all overlock settings, etc.)
-Checked for overheating, to no avail.
-Opened up the machine, and blew out dust with compressed air.
I will now post my specs:
Intel i5 2500k processor
EVGA GeForce GTX 660
ASUS P8Z68-VLX Motherboard
8gb Kingston HyperX Ram
My system has 2 fans, and a CPU coolant system.
Adata 128 GB SSD
2TB Seagate Barracuda HDD
Windows 8.1

Any help would be vastly appreciated.
Thanks a lot!
