Having some trouble with the default display which will not display anything, not even the BIOS!. The default display is a DVI-D output on an onboard graphics card which also has a VGA connection which does not work either. I have tried to use a DVI-D to VGA adapter but that was unsuccessful.

Computer is using:
Intel Core 2 Duo Processor E7400 775
1GB of DDR3 RAM
All of the parts are brand new.

I have also tried using PS2 & USB connections for the keyboard and mouse however there is no sign of them getting power when using USB but when using PS2 the mouse gets power. I have tested the power supply with a PC/SPS Tester there was no problems there. Have also tried using an external graphics card with VGA connection with no luck.

Thanks in advance.

I had a problem very much like that a few months ago, turned out to be a defective cable, have you tried a different cable?

Yes we have tried about 3 different VGA cables + At least 2 DVI cables. Just getting same message each time - "no signal input" then monitor goes to standby. We have tried at least 3 different monitors as well.  

Thanks

In that case you are likely facing a problem with either the CPU or Motherboard, in my experience these are the only two components needed for the computer to POST, has this computer ever booted up? Or given out a beep code to indicate what is the nature of the problem?

something that helps sometimes, is clearing the bios, by repoving AC - and the battery for a minute

Thanks very much for all your help. We found there was a problem with the pins for the CPU on the motherboard slot. One of them was bent and damaged.
