The LED power indicator is flashing (about a tick per second) as if the machine was on stanby but when I hit the power button...nothing.

What you can do is - power off the machine, unplug it from the wall. Now look on the inside of your case - and unplug and replug in all the molex and other power connectors. If that doesn't do anything - if you have a spare PSU you could try out, that might work as well. m 0 l gmatos78 October 17, 2011 9:16:00 PM I unplugged the psu for a few minutes and re-plugged and it worked. Does this still mean my PSU might be bad? m 0 l Can't find your answer ? Ask ! Get the answer Chainzsaw October 17, 2011 9:54:24 PM It's possible. It may have been just one of those smalltime problems with a PSU (weird power problems maybe?). You will most likely be fine now, but if you have any more issues - I would take another look at your PSU. m 0 l Can't find your answer ? Ask !
