I actually went and bought all new PC parts thinking it was my PC or my raptor hard drives. Got whole new spec parts AM2 CPU, DDR ram etc and the other day boom! blue screen again! So I took out the ram replaced it one by one and its all good because my pc would not even go into windows let alone show the bios!
So now thinking its the powersupply I went and got a new PSU, from a Hiper 500w to a Hiper 630w. Hope that does something good!
