My computer keeps freezing/restarting for no reason. My desktop consists of:
Gigabyte P55A-UD5 Motherboard
ASUS 1Gb EAH 5850 PCI-E
Intel Core i5-720
Ripjaws 4Gb DDR3 kit.
Seasonic M12II-620W Power Supply
Windows Vista 32bit
The set up has worked nicely until 1-1.5 months ago when the screen froze over with a green screen with vertical stripes. After reformatting, I have been experiencing the above problem and this can happen 4-8 times a night. I need help
