Compuer will not turn on. Power LED blinking Tags: Homebuilt LED Monitor MSI Power Systems Last response: October 17, 2011 9:54 PM in Systems Share gmatos78 October 17, 2011 1:33:25 PM I just recently (five days ago) built this: MB: Msi 990FXA-GD65 CPU: AMD Phenom II X4 955 GPU: Msi R6850 PSU: Corsair GS600 RAM: 8g (4g x2) 1600 Kingston HyperX It has worked fine but this morning it will not turn on! 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. 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? 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. Can't find your answer ? Ask !
