Ah dadge now, we don't say "to be sure" round here, surely you'd know that .
I'll try the idea of refitting it but I've already called Scan about it. They sent me an RMA number and said for me to send the MB and CPU and they'll test it out themselves and then see what happens then (if there is a faulty part, they'll send a replacement). I just want to know though, my CPU speed is reading 3415 (not 3400, original core speed) so would this be considered as overclocking. They asked a few questions and I explained to them that I used a few benchmark programs to try and find the problem and then they asked which programs so I told them OCCT for the CPU and was met with reply (thats an overclocking checking tool) so I quickly responded saying that I hadn't overclocked it and only used it to test it (which is honest) but the CPU speed is reading 3415, even though I haven't adjusted the core speed when I loaded up AMD OverDrive so does AMD OverDrive automatically overclock the CPU?
