i usually check these forum for solutions so i decided to ask a question here. this was my setup: asrock z77 pro4, i5 3570k, crucial ballistik 8gb 1600 lvp, 64gb ssd, 500gb hdd, nvidia 650 gtx ti and raidmax 630w psu (semi modular). i unplugged the tower to clean it(sentey optimus case). i got a message when powering up after stating that the cmos needs configuring. this has happen to me before and this time i checked the cmos battery and it was 3v. i configure cmos to get my fan speed to quiet but efficient. however, i smelt something burning after the 3rd restart while the pc was in window, then it lost power. it tried to reboot but nothing getting power. i tried another psu but still nothing. i bought a cheaper mobo and it booted to bios with old psu. i tried the raidmax and it booted to bios also. i'm still to connect hdd etc. however, i was wondering is the psu trust -worthy after the mobo was fried? i didn't smell any burn from the psu though. thanks for your replies

If you trusted it when you bought it, then there are no reasons not to trust it now. You did something when cleaning the PC that caused a short, but it's difficult to determine what it was. It could be as simple as a motherboard that wasn't tight enough causing it to move slightly and short out to a post.

Thanks for your reply. I will use the PSU since it is the only one I have that will fit my case using cable management. But no over clocking on this cheap board until I get a z77.
