Q6600 @ 3.2
EVGA 680i LT
4GB Corsair RAM 800
PSU Corsair 750watt
BFG GTX260 (216 maxcore)


Just installed the gtx260 and when I tried to turn it back on, the PSU gave me this....."zzzzt" sound (not too...electricity sounding) and nothing powers on. A case fan stutters then stops. The MOBO still has its LED lights on but it won't power on. When I press case's power button, nothing happens. to get the "zzzzt" sound I have to turn off then on the PSU switch.

Any ideas whats going on?
 
I agree, put your old hardware back in and see if your PSU works for you.
 
yep, to confirm the PSU as the culprit, start with just power to the mainboard, connect one device at a time and power the system up, either it will still refuse to work or you will get to a piece of hardware that caused the problem.

If your still getting nothing from the system, try another power supply.
 
thanks for the help everyone, its confirmed as the PSU.

I have seen that symptom time after time, not once was it a PSU. Not saying it can't happen but it sure sounds like you are tripping the shut down on the PSU.

You sure you don't have something like a fan wire pinched? A bad fan? Did you pull the MOBO out and bench check the system?

Also, on a pcie slot it is very easy to NOT seat the card properly and get the same symptom.

Just a few thoughts;)
 
Hmmmm no you make me wonder.....

I have switched the video card for both slots....

Could it really be something failing after it has worked (flawlessly) for some time?

I changed video cards and my friend said I messed up by not doing it correctly but I don't know...
