Monitors Dead upon Restart

Hello,

I have an:
Coolermaster Cosmos S Case
ASUS P6T Deluxe (latest BIOS)
Core i7 2.93
850W CoolerMaster PSU.
6GB RAM
5 FANS for plenty of cooling
Coolermaster V8 for CPU FAN


90% of the time, I reboot Windows XP PRO SP3, my PC shuts down, turns back on, but both monitors (Dell 2408 FWP) do not get ANY SIGNAL. In order to boot back into windows, I have to turn off my power strip (via the on/off switch) wait 5 seconds or so and turn the PC back on, then the monitor gets a signal and turns on so I can see something and boot back into windows. If that is not done, monitors will always be off, while the PC does boot into Windows and has to be manually shut down in order to perform the trick I found to work.

I have an EVGA GeForce GTX260 Card (single / NO-SLI), I tried to check the temp on it, but GPU-Z says UNKNOWN ARCHITECTURE and I cannot read the temperature.

Also, in Windows my monitors will blink periodically (picture turns black for a split second, entering power save mode and back to normal picture). This happens rarely.

I am using latest (and tried older) drivers, great cooling, tried different BIOS settings.

Thank you very much for all your input.

Yes, it was custom built by a "PRO" company. Everything is compatible, connections are proper and good.
