PSU is ThermalTake Toughpower 600W.
Mobo- Asus P5Q

I have opened up my case today to clean it a bit ( GPU has reached 97C. LOTS of dust).

After putting everything back together, And connecting the power, The P5Q led blinks fast and the computer would not turn on. Googling around tells me this means the mobo isn't getting its' proper power.

I've disconnected EVERYTHING from the motherboard and the PSU but the 24 Pin (Front USB, Front buttons, PCI Ethernet card, Video card, CPU fan, HDD, DVD), And the problem presists.

I've tried testing the voltage according to this: http://pinouts.ru/Power/atx_v2_pinout.shtml

3 to 4 Give a good 5.5V, but 1 to 3, or 2 to 3 Doesn't give any voltage (And using a resistance checker, they are apparently shorted)

Shorting 16 to ground starts the fans.


How can I make sure it's the PSU? I don't have another one around...


(Posted here too, then figured out it'll Fit PSUs section more)

It doesn't need a CPU for the Led to stay up.
