Cant power my pc up

post #1 of 15
Thread Starter 
Hello guys, yesterday night i used the switch in the back of my power supply to turn off my pc. 13 hours later i try to turn it on and it wont work, to make the story short my mobo has the power light on (its getting juice) but i cant ignite the computer, when ever i had a problem like this i used a screwdriver to make the 2 pins touch and the pc would turn on. So my question is; is there a way besides the power/restart pins to ignite the computer? a keyboard sequence another set of pins in the mobo? anything? thank you in advance for your time and patience.

power supply unstable, motherboard unstable, memory unstable, etc....
go to the store or use other hardware and power supply to test.

Try removing the CMOS battery for 5mins, usually works in these scenarios. Motherboards are very strange things....I had that same board a few years ago, and it gave me the same attitude on occasions.

Nope. Memory issues wouldn't stop initial boot process.

Nope. If motherboard isn't starting the boot process then BIOS has nothing to do with the problem.


If the motherboard will not even start to boot, the problem is a short, missing plug, damaged motherboard, or PSU issue. Remove the motherboard from the case to reduce possibility of shorts. Then check the connections and barebones boot.
Once again...

I'm having the same problem, It won't turn on via power switch, funny thing is when I hit the power switch, the LEDs on my keyboard blink, if I hit the power switch enough times, it turns on....eventually. I've checked all connections, I've checked everything, I've booted it up no problem outside the case with the same PSU with no problems, i've checked everything in the case...

If it works outside the case but not inside the case... then it is a shorting issue. Check again.

If it isn't shorting as per Duckie's post then I would say psu is bad. I have had many go bad like this. Intermitent power ons with multiple press's of the power button.

Easy way to check that is to remove psu and unplug everything. And see if you can jump it on consinstantly. If you can then mb is the issue, if not then psu is the culprit.

Hmm, What would be shorted in the case? I checked all of the stand-offs ( Things to bolt the motherboard down) and non of them are in the wrong place. I checked the PSU with 3 different other computers and no problems. I've tested the voltage, it's stable, and I can power it on by jumping it with a short wire.
