Hi, i just built this computer 3 days ago and ever since then I have sometimes got random freezes. It sometimes happens when i start up, downloading something, browsing the internet, or playing a game. I have read lots of forums regarding this problem and they all say the problem is either ram, or my power supply. These are my system specs, Thank you AMD Athlon II X2 3.0ghz (overclocked to 3.6ghz) Asus M4A785-M motherboard. Intergrated ATI HD 4200 (overclocked to 800mhz) 4gb of wintec DDR2 800 Ram Seagate Sata 500gb of hardrive. Powerlab 480w PSU.
