Hi there, I put together a system recently and have had errors since installing windows 7 onto the computer My Build is; i5 3570K Corsair Vengeance 8gb 1600mhz Seagate Barracuda 1TB Nvidia GTX 660 Now the Bsods' I've been having recently are: Driver IRQL not less or equal Pagefault in non paged area Kernel Security check failure All of these were read off of Who Crashed on Windows 8 and were the same errors I was getting on Windows 7 The BSODS happen at very random times, it's so odd infact that I can run CPU intensive applications like Prime 95 for hours on end just fine but then If I open up a browser and watch a video or something really basic, I'll end up with one of these errors. Even gaming doesn't give any BSODS, just happens at random times. I would really appreciate any help at all because I saved up for a fairly long time to build this computer and it's a tad annoying that I can't get it to work properly. Thanks very much, Yad
