  1. I have changed video cards, used both AGP and PCI. I've tried different monitors. The display will still not turn on. I have cleared the BIOS. Nothing. I removed the memory to check and see if the processor was fried, but I got the beeps telling me the processor is fine. What do I try next?

    Onboard Video on Motherboard?

    Does your mobo have onboard video?

    Hello and welcome to Techspot.

    Can you still use your old videocard?
    If so what happens when you do.

    Video Cards

    Th old one (AGP) does not work. I've tried a brand new ATI (PCI) card and a different AGP card, but nothing works.

    Bad Motherboard Look Like

    The only thing left that it could be, besided the PSU, is the motherboard. I really doubt a bad PSU would cause only the video to stop working. Do you have any other cards in your PCI slots? Sound card, modem, NIC? Try removing them. If you could determine that they don't work as well, then you know it's a bad motherboard.

    No BIOS Beep Codes?

    Do you get any BIOS error beep codes at boot?

    I've tried different monitors. I get the no signal screen from both of them.

    It's got to be the motherboard. All of the cards work fine in my other system, as well as the harddrive. The only part I haven't eliminated is the CPU...Could the CPU cause this or should I settle on buying a new motherboard?

    It might be nay one of those two trying using ur CPU in some other MB if u have access to one, this will help u find the suspect party.

    I agree with your conclusion, that it`s the mobo that`s defective.

    All Three Video Cards?


    Did you not read the earlier post: "Th old one (AGP) does not work. I've tried a brand new ATI (PCI) card and a different AGP card, but nothing works."

    It's super unlikely that it's the video card. It's got to be the motherboard.
