Ive started to have a problem on my system (in sig). The power button wont turn on my pc any more, I have to flick the switch on the PSU off/on, the longer the PC has been "off" the more flicks it takes.
Other than when I unplugged it to let it do a full shutdown to see if that would help, I dont unplug it.
Power button works to turn the pc off/force a shutdown so its not a dodgy connection on the button.

It boots totally fine once its started, no issues with OC etc, no BSOD's.
All temps and voltages look fine. It used to work fine.

Recent hardware changes: Stuck in a AverMedia Live Gamer HD Lite (works fine) I think the problem occured after I put this in, rather than before, but not straight away.

about 1 in 30 times, the front power button does work to turn the pc on.

Only other recent issue I have had with PC, is with a el cheapo Chinese usb repeater/hub thing that whenever I plug it in it BSOD's my machine, but no other USB device does this so I am blaming that device.

Any ideas? Im thinking its a minor short somewhere? The AverMedia card is up against a waterblock (acetal tops) but it doesnt seem to have any weight/stress on the card.
 
It will happen to me if I do force shut down, but very rarely, and if it does I need to unplug the psu from socket plug it again and it works fine. It must be something to do with PSU protection
 
but, it does it basically every time, and didnt always do it with this psu? Or do you mean, the PSU is doing it because of something else?

Edit:
Should point out, the on mobo button doesnt turn it on either, and when i flick the PSU switch and it turns on, its not that it turns on after i press the front button, it just powers instantly

try disconnecting power button from the case and power connecting two pins on mob, maybe switch is getting stuck, check for any broken cables On psu, but it might be mob as well

err, probably. Its an XFX 1250w black pro thing, Next weekend a mate is coming over to test a load of his kit on my spare rig, so I could always stick in the 700w from that rig during that time, Dont have to connect everything up :D
 
Morfinel, surely if it was just a stuck button, it wouldn't work to turn it off reliably, and the switch on the mobo would work fine?
 
Ok, will test it with my spare next weekend when i get some time (the mrs is away). If it is, glad its still in warranty, I want to be saving my money for new kit, not replacement parts :/

Edit: or not, I appear to not have an account on XFX, although I have had two in the past...but that means I can't have registered it for the 5 year warranty, and the standard 2 year warranty ran out in feb ffs.

Or, you think that if i just unplug the mobo power, and short the pins on it, that will be an adequate test? If the PSU doesnt turn on then, it confirms its faulty? Obviously if that happens, then since I will have to take it out, and as such re build the whole machine (cables routed behind mobo etc) then I will test it in my other machine/the spare psu in this machine etc. To confirm before I send it off for RMA
