AGP slot or Video Card problem? not sure!!!

emtau · 02-13-2008, 03:25 AM

I had a problem with my video card so i removed it from the AGP slot, plugged my monitor to the built in video out from my motherboard and it worked again.

Now I got another Video Card (ATIRadeon...), plugged it to the AGP slot and there's a "no signal" displayed on my monitor.

Is it a video card problem or my AGP slot is not working anymore???
need help.

Hi, welcome to TSF

Check in BIOS to see if onboard graphics has been disabled. It should do this automatically when you fit a card, but you might need to do it manually.

Is the monitor plugged into the card or the onboard connector?

Is your PSU powerful enough for the new card?

How can I check my AGP slot in BIOS? I know how to access BIOS but I dont know where to look? please tell me how in detail cos i dont know much about BIOS.

When i plug my monitor to the card, its just a black screen. unplugged it and plug it into the onboard connector with the card still sitting on the slot, still black screen. But when i remove card from the slot and monitor connected to the onboard, it works.

What model is the Radeon card? Is your PSU strong enough to handle it? Open the case and post back with the details from the PSU label. Make/model, total watts, amps for +12V.

Whenever you upgrade from onboard to a graphics card, the power requirements of your system increase, so if the PSU doesn't have enough amps on the +12V line, the card won't work.

Assuming the PSU is strong enough, we can go to the next stage. With the monitor plugged into the onboard connector, start Windows and go to Control Panel > System > Hardware tab, click the Device Manager button, right-click the onboard entry for Display Adapters and select Uninstall. Close down Windows, switch the computer off and unplug the power cable. Fit the new graphics card and switch on. Keep tapping the 'delete' key after switching on until the BIOS appears. Go to Advanced Features or Advanced Chipset (might be worded differently in your particular BIOS), select 'disable onboard VGA'. Press F10 to save the change, then Exit to reboot. If this fixes it, Windows will load and you can install the Catalyst driver for your Radeon card.

What was the original problem with your old graphics card? It could be that your AGP slot on the motherboard is faulty. Check the motherboard for any bulging or leaking capacitors, and blow out any dust from the card slots with a can of compressed air.
