I actually posted this in another area by mistake.

My monitor won't recognize either of the new video cards I have. Both are supposed to be compatible..but I could be wrong and would that cause this problem.

I put the card in and hook up monitor..nothing. I move the monitor to the original
port, still nothing. I remove the card and the monitor works fine. The fan on the card is running which leads me to believe it is working or at least installed correctly.

I am wondering if this is a problem with the AGP slot, could it be damaged?

Any help would be appreciated.

A focused troubleshooting checklist and explanation to follow after ’s symptoms (new AGP cards spin but produce no video) and ’s BIOS/IRQ comment. The goal is to quickly determine whether the cards, the AGP slot, BIOS/config, or something else is at fault.

  • Verify basics first: confirm the monitor is plugged into the video card output (not the motherboard), try a different cable and a different monitor/TV to rule out a display/cable issue.
  • Reseat and inspect: power down, remove the card, blow out the slot with compressed air, check the edge connector for dirt or bent contacts, then reseat firmly so the AGP latch engages. Check the card and slot for scorch marks or melted plastic.
  • Listen for POST/beeps: a motherboard speaker will indicate video errors at POST. No POST signal (and appropriate beep code) points to hardware-level initialization failure rather than a driver/display problem.
  • Clear CMOS / BIOS defaults: reset the CMOS (jumper or battery) so the BIOS re-detects devices. Look for "Primary Video", "Init Display First" or similar; if the BIOS only shows "Auto" or "Onboard", a reset or BIOS update can sometimes restore choice.
  • Swap-test to isolate: try each new card in a known-working computer, and try a known-good card in the problematic motherboard. If the cards work elsewhere but the board still shows no video, the AGP slot is likely damaged. If the cards fail in another PC, the cards themselves are defective.
  • Compatibility and safety notes: confirm AGP card/board voltage/keying compatibility (1.5V vs 3.3V notches) and use ESD precautions. Fan spinning only confirms power is present, not successful GPU initialization.

If swap-testing points to a bad AGP slot, typical remedies are motherboard repair/replacement, using a compatible PCI card as a workaround, or RMA the faulty board/card if under warranty.

BIOS settings?

Member Avatar for relax159

The bios video is set to auto, I can only change it to onboard. There is no option
to "disable" and I am pretty sure I used to be able to do that.

I am getting the feeling the agp slot may be fried. Bummer.

Seems like a port/IRQ conflict to me.
