its not the motherboard anymore...
Just had a run in with my PC turning on for 2 secs then shutting off.
So I proceeded to:
Yank everything out and check everything.
check the supply box
It came down to me thinking its the motherboard. It wasn't fried cuz their was power still going through it as indicated by the red and green lights.
Now this is the part they don't tell you.
Disconnect the Power On button from the motherboard, use a philips or flat-tip screwdriver to connect the pin and manual start up.
Sure enough the PC booted up as if nothing happened and works fine.
Now my question is, what do you do when your power on switch gets screwed over?
Besides trying to clean it, which is next to impossible since the back wiring is blocked by the bolted hard drive holders.
Do i have to buy a new case or does anyone sell power on buttons motherboard specific?
