windows 7 cutting off unexpectedly

Hello, I have a dell desktop that is running windows 7 pro sp1 that just cuts off with out any warning my first thought was it was a hardware problem so I ran the diagnostic tool that checks the cpu, memory and hard drive, etc and everything passed so I am thinking it must be something in windows creating the problem but no errors in the event log....... any suggestions or any tools that can stress windows to see what's going on?

It sounds like a fault with the PSU in the machine, have you tried an alternative kettle lead and plug socket? Maybe look into replacing the PSU. Could even be a failing CPU or HDD.

I would also advise to disconnect any external devices from the machine until the issue stops.
