Ok it sounds as if ya Power Supply Unit (PSU) may have gone faulty. Generally when a PC won't turn on it can only be caused by a few things. a faulty PSU, a faulty component/card stopping the PSU from working, Motherboard Fault. Faulty RAM

Ya have to isolate which one. So first open ya case up, then take note of the way things are connected. (Write them down, draw a picture) Then unplug ya Hard Drive, try it,  & then ya CD/DVD & try it, take any add on cards out, try it... & so on... to isolate ya faulty bit.

If it still doesn't go after removing everything except the Motherboard, then ya gonna have to try another Know Good PSU.... of course if it doesn't  work then, ya have a MotherBoard fault.

Just work thru it slowly.. and ya be all good.

How do I know if the power supply is bad on gateway gt5676 computer? I push power button and nothing happens. I unplug it and the green light flashes on the power supply( Bestec ATX 300 12 EB3). Plug it...

u can buy power supply testers, just a device you plug the power supply into, or try a new power supply. but if nothing is happening no fans etc theres a good chance its just the power supply.

It won't turn on!

Flashing green battery means it is in suspend mode. Pushing the power button should bring it out of suspension, however, one of the reasons I deactivate both suspend and hibernate mode is because the seldom work right. I would disconnect your A/C power cord and remove your battery from the laptop. After about 30 seconds plug them back in and your commuter should start again. Let us know how things go.
