Hey Raiddinn, Merry Christmas and thankyou very much for your long and informative reply. Interestingly, around 6 months ago my psu did go however, as it was under warranty, I managed to get a new one. It is, quoting my newegg order, '1 x XFX Black Edition P1-750B-CAG9 750W ATX12V v2.2 / ESP12V v2.91 SLI Ready CrossFire Ready 80 PLUS SILVER Certified Modular Active PFC Power Supply'. I may be able to borrow one from my bro, however, I would like to leave that as a last resort because I dont think he will be very happy with me if I start taking his comp apart
My motherboard, which to be honest has not impressed me very much, is a '1 x ASRock 870 EXTREME3 AM3 AMD 870 SATA 6Gb/s USB 3.0 ATX AMD Motherboard'. Do you think that I should just buy a new processor and motherboard?
Thankyou all so far for all your help. Much appreciated.
