pc keeps shutting down

RobTi · 20 Mar 2012 at 19:33

Hi as above no blue screens just the pc shut down unexpectably from desktop then the option to restart in safe\normal.

So have run memtest for 4 hrs, prime for 5 hrs and did a hard drive error check all negative no high temps (although the S\B was too hot to touch, have since put a heatsink on it),Also did a clean install 3 times and got the above when starting to install updates.

Any ideas on what it could be

Dell c521 win7 ultimate 64bit 3gB memory athlon x2 4500

Sounds like its a few years old, so I'd put money on the power supply being the issue. They don't put particularly good units in those OEM computers.

+1 for PSU.

Try another if you can.

Thanks as its a Dell c521 is non standard any way to test a psu with a meter before any more money gets spent on it

Thanks for the reply, only its not mine its the nephews, anyway got it running on an old spare psu with the case in bits at the moment to see if that solves it and then go from there.

Just to update been running all day without a hitch, so must have been the psu if it crashes again it for the recycle bin and he can upgrade sooner than he thinks.

Thanks

Yep that random shut down is a pain, could work fine for days and pop one day, it just shuts down.
