From my experience it's usually mobo or RAM that could be a spanner in the works. I have so many bits of hardware lying about that I could probably build 3 extra PC's. Therefore I just keep swapping out bits until I find the culprit. It's worth having extra cheap hardware about.

@Jay85: I tried my CPU in a friends PC and it worked fine. I then tried his in my pc and it didn't work.
@KnightsWhoSayNi: Yeah, I've reset bios to defaults many times.
@Speed: Yep, latest bios update is on there. The issue was happening before I flashed the bios too.
@bigjimmyauk: I've just asked my mate if I can borrow his pc for a day so I can test every component. I should be able to test PSU, RAM and even the mobo properly so hopefully I can at least find out which component is causing the problem. Problem is asking this guy if I can borrow his pc is like asking if I can borrow his missus. He's quite attached to it shall we sayHopefully I can persuade him to part with it for a few hours.
If this fails though then I may well take up your offer and send you the whole thing. If anyone can figure ou what's wrong with the bloody thing I'd be happy to pay for their time.
I'm starting to think this is maybe some weird compatibility problem between some of my components. Maybe they all work well individually but together they cause problems.
Well there is a compat problem in that system somewhere but it's finding it thats proving difficult. Hopefully your friend will part with his rig for a day or at very least let you around there to test things out thoroughly.
Haven't managed to get hold of my mates PC yet but I have done some more testing.
I been playing around with the cpu cores in the bios and enabling/disabling different combinations to see what effect it would have. No matter what I try, whether it's all 4 cores, 3 cores, 2 cores, its always the last worker on the Prime95 test that gets stuck. I know you can't switch off the first core but I tried running just one core on its own and windows wouldn't boot. Should I be able to run off one core?
I'm not sure what all this means as I don't know what order the cores in the bios appear in Windows or indeed Prime95. But the fact the last core in Prime95 is always the faulty one is very strange. Either this is always core 1(the one I can't disable) and that is faulty/incompatible, or there's some wierd thing going on thats disabling the last core everytime.

Jeez, just read about your problems mate. Not good.
Anyway, just been reading up on your mobo and I found this feature;
"Core Unlocker
ASUS Core Unlocker simplifies the activation of a latent AMD CPU-with just a press of a button. Enjoy an instant performance boost by simply unlocking the extra cores, without performing complicated BIOS changes."
I dont have any experience of AMD CPU's so I dont know if this is relevent or not for your own setup.
My old Intel Q9550 would only show 2 cores active if I didnt enable the Intel Speed Step and HT option in BIOS, weird eh?)
Have you tried to DISABLE any Power saving features in the BIOS? C1E etc....
Good luck, hope you nail it soon.

So i've finally figured out the cause of all this. Seems it's definitely the motherboard that's causing the problems. Whether it's faulty or what I don't know but there's something about it that the rest of my system just doesn't like.
After trying another PSU this morning and that also not working I took a gamble and went and bought a cheap ass AM3 mobo. Set it all up, reinstalled Windows and all my drivers and it worked first time. All 4 cores of the CPU firing. Prime95 test works perfectly and also tried Cinebench. CPU is now scoring 4.10 compared to 2.90 from before. The GPU test is up to about 57fps.
I'm not sure where this leaves me with OCUK now. Having already RMA'd the mobo to them and they returned it as not faulty, i've now got a practically brand new £160 mobo sitting next to me that is totally useless(to me at least). I guess I need to call OC and see what they can do for me.

It is strange, but the problem is if you RMA it again, comes back not faulty then you'll be charged a testing fee I expect. Maybe contact OcUK Returns with a link to this thread, you might be able to get a refund instead if it isn't that old.

Have u checked temps? I had a diamond viper hd2900xt 1gb and i had problems like this turns out the gpu cooler was ****ed and it was hitting around 100c which was killing it. Just an idea?
