Hi
I am not the AMD guru but from reading your post my first thought would be that your PSU is far too small and I suspect that it is a power problem. You should really be using about 550W upwards for safety.
So the next thing is to change your PSU. Never buy a cheap and nasty power supply they can go wrong and take out all you other expensive components at the same time. Not only that just because it is marked 600W often they are nowhere near that rating. Purchase a good make like Seasonic, CWT, Corsair, Thermaltake, Enermax, Gigabyte, Coolermaster, Antec, etc and try and get one with a single 12V rail if possible. I would advise you to get one of about 550W minimum. If you can just borrow one to test with then fine do so.
