Power supply changed - No video signal

[Corson27]

Hi,

I'am new to this board and I hope to find help for my problem.

I had a running system with foillowing components:

P4C800-Deluxe Mainboard
1GB Corsair memory (2x512)
330 W Power Supply (chieftec)
2,8 GHz Intel
Ti 200 Geforce-2
Scsi Adaptec 29160

Yesterday I swapped the power supplied with a newer one. Chieftec 420W
power supply.

Now I get no video signal. All fans are running, the green LED is on
and there are no beeps codes from the mainboard.

What I tried so far:
- switch AGP card with a PCI graphic card - same problem : no video
signal
- startet only with mainboard, memory, cpu and AGP card - same problem
: no video signal
- put my old power supply back into work - same problem : no video
signal

I simply don't know what to do to solve this problem. Could it be that
the the mainboard has been damaged just by exchanging the power
supplies ?

Don't forget to plug in the 2x2 +12V power connector to the motherboard.
The motherboard has two power connectors.

HTH,

Sounds like the motherboard has failed.
