PC Won't Boot up
3 days ago I spent neally £2500 on a Quad Core 6850 PC with 2 Nvidai 8800 Ultras and 8 GB Ram. The case is anAntec P190 with 2 power supplies. The computer worked fine for 3 days but won't now power up.
I used to switch on the one power supply so the top 2 fans would come on. Then when I switch the 2nd supply on, the fans would stop, I would power on the pc at the front, the fans come back on, then the pc boots up.
Now, the top 2 fans come on as usual but when I switch on the 2nd power supply, the fans stop (as per usual), the mothrboard light come on, but I can't boot up the PC.
The only thing I can think of that I did different is that I plugged both supplies into a Surge Protector. I unfortunayely noticed after that the maximum load on the surge protector was 13 amps, both power supplies are 13 amps each.

Also, is the connection between the P190's power supplies attached properly? This is what causes the power supplies to power up together.
Whats this switching on PSU's at different times? you should be connecting the two with a atx power supply header,as CB said, like in the picture.
