Hi so i bought a computer a while ago and ever since i got it its been crashing on games completely shutting off, i found this to be my cpu to blame as my cpu temps were off the roof and my cpu fan isn`t the greatest. my Cpu is OC to 4.3ghz because it came overclocked so im just wondering how do i get it back to normal so it dosent make me crash on games. btw heres my pc specs from where i bought the pc http://www.jdwilliams.co.uk/shop/orion-performance-quad-core-gaming-pc-bundle/ov269/product/details/show.action?pdBoUid=3715#colour:,size:
