why did u buy a PSU ? when that might not have been the cause.

I need to know temps and voltages first. to be able to point u in the right direction

you could try reseating the motherboard, there could be a short somewhere

Well if it's not the PSU then it could be either the mobo or a faulty component resulting in the sudden shutdown. I'd strip the PC bare of things that you can do without and check for the shutdown problem and then plug things back in 1 at a time. If the removal still results in a shutdown then I'd suspect the mobo.

you know what? try as i might i cant get motherboard monitor to work as there is no support for my board.

PSU, I reckon. These cheap PSUs have a habit of acting up. Can you make the problem come on faster by stressing the rig, ie. Orthos and gaming?

can't be that, as hes got a new one, and he still has the problem!

AS some one said earlier, i would strip the PC, run it on bare minimum stuff, OUT of the case (in case its shorting inside the case somewhere)

basically do it on a box/cardboard out of the case, run the PSU, CPU, RAM and GFX card only, ram chips only 1 of them, try all 3/4 slots is u need to.
if that boots into the bios fine, then add the hard drive, see if that then gets into Windows.

Good luck, let us know how u get on

I should learn to read

In that case, running it outside of the case is definitely a good starting point.
