Power problem

[CrAsHnBuRnXp]

Hey guys. I just upgraded from S775 to 1155 and purchased an i5 2500k, Asus P8P67 (rev 3.1), 2x2GB G.Skill DDR3 1600, Corsair HX750w. Everytime I shutdown my computer (whether its for 30 seconds or over night) my computer will not power back on on its own. I have to kill the power from the PSU via the switch for 5-10 seconds, flip the switch back on and it boots right up.

This becomes a pain in the ass after a while and I was wondering if anyone has had any other experiences with something happening like this and what you did to solve it (if at all).

The really weird thing is, whenever I have to use the above method to get the computer to turn on, the BIOS gets reset to factory default when I never touch the CMOS battery or jumper.

Thanks for the input guys!

Makes sure you have the latest bios revision, I have had this happen on some giga boards before. Also walk through every page of the bios (if you haven't already) and set up everything manually.

sounds like a bad (dead) cmos battery. Change it out and I betcha problem solved.

Ive done all of that already. Doesnt seem to make a difference. :-\

Ill give that a go. Ill find an old motherboard and pop its CMOS battery out. Hopefully that will work.

Another PSU to test?

Good luck, It should cure the problem.

What? I merely made a suggestion. In case the PSU is latching-off (for protection circuits such as SCP or OVP), changing it may work.

I'd also try the card at different PCI-E slots, or give an another card a go.

Never said a thing to ya. I hit the wrong emoticon.
Fixed now..

Thing is, he had a GameXStream before. So his PSU must have been changed as well. There's a chance his new unit may be defective.

Oh and, Corsair's QC with those units isn't too shiny these days. I've seen a few of them fail in the past months

Finally stopped being lazy and switched out the CMOS battery with another one I found lying around. Still the same problem.

My only workaround for this is to put the computer to sleep every night before I go to bed and then I can just tap the mouse and it comes back on. I kinda hate doing this.

So my suspicion lies with the motherboard itself or the PSU. Neither of which I can test without becoming a royal pain to my father or my brother who happen to have the same board and power supply.
