Agp slot not reponding.

  1. I have a Dell 4600 with 3.0ghz P4 HT Cpu, With 768mb ram, and a 7800gs evga graphics card. When I turn on my desktop I get no signal from my video card and my moniter remains blank. Ive tried using 3 other moniters and i get the same issue. I notice when I turn on my computer the cpu and psu fans are both spinning and working fine however the fan on the video card isnt, so i tried plugging in annother video card without a fan (5200fx 128mb) but i still dont get a signal I think my agp slot may be broken. Any suggestions? I know it isnt my psu (500w).

    Does your computer sound like it boots into Windows? I mean does you hard drive run for the appropriate amount of time to boot into windows. After your machine "boots" can you push the power button in for a second and have your computer power down normally without turning off instantly or having to push and hold the power button down for 5 or 6 seconds to force the computer off. If it does boot into Windows and powers down normally then it's probably not your PSU.

    If it doesn't boot or if it turns off instantly when you push the power button for a second then it could be your PSU or motherboard. I don't think you have an underpowered PSU, but it may be a broken PSU. Just to keep you from buying an older P4 board, I'd borrow your friends PSU for a few minutes and test it in your system.

    If your computer does boot into Windows then it sounds like you are correct. I'd inspect the slot for debris, and as a last ditch effort I'd try clearing the CMOS and then test the motherboard with the 5200 in the slot.

    I am certain that windows boots, i actually hear the default windows startup sound. And I dont know what you mean by cleaning the CMOS can you enlighten me?

    I dont think my computer is starting up anymore. I hear 2 short beeps about 20 seconds or so after turning it on. What does this mean?

    This means that your motherboard is broken and it needs to be replaced.

    The CMOS is the chip on your motherboard that contains your BIOS. The BIOS is the Basic Input Output System. The BIOS controls your motherboard at a very low level until your operating system can take over the job.

    If you open your case and look at your motherboard you'll see a large watch type battery sitting in a battery holder on the board. There should also be a set of three pins right next to the battery and two of the pins will be shorted with a jumper. To clear the CMOS you have to turn off or unplug the PSU, move the jumper from pins one and two to pins two and three and remove the battery from the holder. Let the computer sit for a few minutes and then replace the jumper back on pins one and two and put the battery back in the holder.
