my computer turns on for like 2 seconds, all the fans are spinning, however nothing is on the screen and then it turns off.
also the computer restarts itself to follow this pattern again and again.
the only way to make it stop is to turn off the psu switch or unplug the computer from the power source.

what is the problem? is it my ram? is it my power supply?
help would be very much appreciated
thank you!

This happened to me last week. I was using my computer and it just shut off. I went to start it up again and the fans would spin very briefly. Pulled out a DMM and checked the voltages and the PSU was dead. Put in a new PSU and it started right up. Do you have a Digital multimeter?

This does not mean your PSU isn't at fault, I have jumped PSU's that seem 2 work fine when not plugged in to the mobo. Some even pass the tests on a PSU tester but still fail when connected to a system.

Oh, and DMM= Digital Multi Meter :)
