Hi all!
I am an experiienced computer builder but I've purchased a new i7 machine that I can't seem to get working. Iv'e got all new equipment as follows:

MSI x58 platinum ms-7522
Intel i7 920 cpu
Corsair TX750W psu
3 * 2gb Corsair XMS DDR3 ram @ 1333mHz 1.5V
1 tb Seagate
nVidia 9400 GT GPU

My problem is that I can not get any display when i turn the computer on, It turns on for 25 seconds and then shuts back down with no display. In the process of troubleshooting i have switched motherboards for a new one of the same model, tested with 2 other known working gpu's, all the pci-e slots, and 3 different monitors with both interfaces (DVI and VGA). I have returned my ram that was 2 * 3gigs @ 1600mHz 1.65v and purchased the new set which is at 1333mHz 1.5v. I have also upgraded my psu from a 450 watt to the current 750 watt.

Everything looks the way it should as far as LED indicators on the mobo, and I am not getting any beep codes. If I remove the RAM entirely, I do get the expected beep codes. The only thing I have not tested is the CPU, but I feel if that was at fault, I would receive boot codes.

Really at a loss here, any and all help is appreciated.
Thanks!
Dan
