I am having a problem with my system not displaying. I have a evga 8800 GTX graphics card that is connected directly to my power supply so it is not sharing a line with anything else. The problem is that when i start up, everything runs and sounds fine but my monitor still acts as if my computer has not been turned on. I've tried different slots, different ram set-ups, different mobo, processor and I got two of those cards and they both do the same. Just looking for opinions on what might be wrong.

Sounds to me like the only common denominator in your testing is the monitor. Do two things:

1. Plug this monitor into another computer
2. Plug a different monitor that you know works into this computer.

Does the problem follow the original monitor or not? That's the best way to tell if you're looking at a problematic monitor or problematic computer.

Try disconnecting the monitor cable and see if you get a "no signal" message or some other type of display. If you have another PC or laptop, connect the monitor to it and see if it works.

If so, you may have some kind of conflict on the video cards. Have you tried a different card on the system?

Also, does your system by any chance also have integrated video? If so, you may need to go into the bios and disable it.

Are you using the VGA connectors or do you have DVI? This could also be the source of your problem....

Just a few things to look into. Hope something here helps.

I have tried new monitors and tested both they work fine, there is no on-board graphics, it shows that my monitor is connected to my card but it still wont display, guess I'll have to get a pci card and try that. I can't test my cards but I don't think that I would be sent two bad cards but any other suggestions would be nice.

It would be a surprise to me that you received two bad video cards. I'm thinking you must have some form of conflict or incompatibility.

Try temporarily using another card and see if it works. If so, you can try tinkering with the different settings and see if you can get it to come up.

What video card did you have in the system before (if any)? If you did - did you remove it and it's drivers?

Good luck....

I think you're right that it would be very unusual to get two bad cards.

Try removing all other add-in cards and any peripherals that are plugged in. So when you start, the computer has only the minimal necessary things: power, keyboard, mouse, monitor.

If you have a conflict, this should eliminate it. If you boot fine, then add in one card at a time and boot. If the cards let you boot ok, add in one peripheral at a a time. Once you add in a device, and can't boot, that's your problem. Move it to other slots and see if that solves the problem, check your device settings, etc.
