Monitor is not receiving message from the CPU?

Question

I just built a computer by myself. The mother board is an ASUS P5NSLI (it doesn't have an onboard graphic card). I just replace an intel pentium D 915 with an intel pentium 920. The two processors are all intel D 9 series, having the same socket type 775. My graphic card is a egeforce 7600 GT. When I turn the computer on, the case light is on, all of the fans, including CPU fans, graphic card fan are on. The monitor power is on, and itself works on other computers. I really hate to return stuffs back to the store, poor them. Please help me to diagnosis it

(The monitor cables are probably connected. I try to unplug everything internally, and then replug them in, I also clear up th CMOS, take out the batery and reinstall it, my graphic card doesn't need more power cable on it)The graphic card worked ok before, before I installed a different processor, but it is not much of difference. Should I return everything back to the store :(

Answer 1

Sounds like you already have. If the monitors works on another PC then it's not the monitor. The video card is snug? Try re-seating it. What type of card is it? PCI, AGP, or PCI EXpress? Make sure your motherboard can support the card. If all fails return the video card or have it tested where you bought it.

Hope this helps

Answer 2

The are two chords that come out of the monitor ... one goes to the electric switch for the current supply ... which you have connected I guess as you said the monitor power is on ... then the second chord that should be connected to the CPU from the Monitor ... that transmits the signal from the CPU to the monitor ... you must have either forgotten that or that must be loosely connected ... check and plug it in properly !

Answer 3

As i know your graphics card is a PCI Express card. I would suggest you to try removing it and reseating the card or check the card on a different computer.
Also try removing the processor and reseating it again. I hope this helped.

Answer 4

Does the computer boot up? Or does it seem to do nothing?

What power supply do you have?

If you swap the processor back, does it work now?

You could have a lemon processor.

Answer 5

try disconnecting internally everything that isn't needed for boot....then one by one put them back in, rebooting each time to see which one may be causing a hardware failure. Usually this is caused by a voltage spike from the power supply mis-regulating...but it rarely causes physical damage to the components.
