I usually keep my computer on but i decided to shut it off and left it alone for about an hour. Came back and it wouldn't turn back on, it just sat there dark and dead. Turned off the switch on the back of the PSU and turned it back on again, nothing. Unplugged the psu power cable and plugged it back in nothing. Opened the case and checked to see if my case connections were lose and they weren't. So i started checking the power connections to the MB, pulled out the 24 pin pulled out the 8 pin, plugged them back in. Computer turns on!! ***?

Think nothing of it, turn it off again, put the panels back push it into it's normal place, push the power button....nothing! Pull the psu cord out, take out the 8 pin put it back in and computer doesn't turn on.
Did the same thing, pulled the 24 pin this time, plugged it back in and bam computer is on. Turned it off, left it for a minute and it won't turn on. Pulled the 24 pin again and it goes on.

Do I need a new MB?

Man, what a great challenge. I really can't think of what this could be. My only thought was a CMOS issue of some kind... have you tried clearing the CMOS completely? Crazy... will be really interested to hear what happens with this one.

Good luck!

Looks like it's the PSU problem. Had a half tired old 750 corsair sitting under the bed. Plugged it in, comp turns right on. Did a bunch of on and off tests leaving the pc for a few minutes up to an hour and it turns on normally.

Wow that is a really weird issue, do you have another PSU that you can test the computer with?

Please do not bash the fact that I use a gaming laptop as my main system, or tell me to sell it and buy a real gaming computer my life does not permit this at the moment. smile.gif

There ya go.

Newegg has the Corsair 750W PSU on sale right now for 104.99, through March 7 you can use the promo code EMCNGNJ22 to get another 15% off that, making it roughly 89, and there's a MIR available for ten bucks.

79 bucks isn't too shabby. smile.gif
