Hey guys,
Got an annoying issue here, my PC is randomly restarting ONLY while playing games. Games that are within my hardware limits. Shortly after I load up a game (specifically WOW, Final Fantasy XIV, and Guild Wars 2) my PC will either just plain restart, once or twice is has given me "glitches" all over the screen and freeze, or I have gotten a BSOD twice.

Here are my Specs:
Operating System
Windows 7 Ultimate 64-bit SP1
CPU
AMD Phenom II X3 B75 25 °C
Heka 45nm Technology
RAM
4.00GB Single-Channel DDR3 @ 669MHz (9-9-9-24)
Motherboard
ASUSTeK Computer INC. M5A78L-M/USB3 (AM3R2) 36 °C
Graphics
NS-24D510NA15 (1920x1080@59Hz)
2048MB ATI AMD Radeon HD 7700 Series (ASUStek Computer Inc) 32 °C
Storage
1863GB Western Digital WDC WD20EZRZ-00Z5HB0 ATA Device (SATA) 26 °C
7GB SMI USB DISK USB Device (USB)

I had the issue before installing new processor, HDD, Motherboard, new OS, and GPU. I ran a memory scan on my RAM to see if the memory was the issue, but they both checked out ok.
