Also had the same problem so i eventually gave up and took it to the shop, turned out i had an extra brass stand off in my motherboard and it was causing it to cut off. worth a look?
My gpu Is an ATI Raedon 5750 1gb, CPU is an Intel I5 750 Quad core overclocked to 3.36ghz.
as for temps my gpu is roughly 34c idle and 37c when engaged and my cpu is at its highest 37C.
