System shuts down after a few minutes. Green light on power supply stays on. I have disconected power supply lines and reinstalled. No error message on start-up. Suspect power supply but want to rule out any other components.
In addition to that, check also the heatsink on the processor if it needs dusting, it may be filled with dust that it doesn't allow air to pass through to cool off the processor.
Please keep us posted.
Hi, the problem could be that your CPU fan may possibly have died as this will cause your CPU to overheat and the system will shut down automatically to protect itself.
On the other hand it could be the power supply unit. Open the box and turn it on and watch your various fans, some PC's have 2 or 3. if it is workin nice and fast then more likely the PSU. Before you open the box make sure you will not be voiding any warrantys that you may have from when you bought it.
Let us know how you go.

First I checked the fans as suggested by SEAJADE, all working. Next I blew out the dust with compressed air per LEMMOR.
System has been operating for 8 hours. I would not have thought that dust would have caused processor to overheat.
Thanks!! I could have spent $50. for a PSU that I didn't need.
I have the same problem. It was working fine then I unplugged everything and blew it out with a Duster like I always do. Never have had a problem before, then when I went and plugged everything back in and turned it on it started powering up then it shut off. And it keeps shutting off now and will not stay on. It has powered all the way up to my desk top then shut down. That is as far as it will go. Please help!!!!
