I tried installing a AGP card on my Gateway 510 and when doing so, my computer turns on with no picture but gives a red blinking light at the very bottom of the motherboard, right under the last pci slot. I have a 400 wat power supply and the new card takes 270. Any Ideas this is the link for how the motherboard looks like http://support.gateway.com/s/MOTHER...

Did you go into the BIOS, disable the onboard video & set the Initial Display to AGP? Also, there is no AGP card that requires 270W, if anything, that's a wattage minumum requirement for the entire system when the card is installed. It would have helped if you'd have listed the make/model of the card you're installing. If it requires an aux power connection, did you plug it in?

yes i disabled the on board and did set the initial display to AGP. The card is VisionTek - ATI RADEON HD2400 Pro 512MB. http://www.bestbuy.com/site/olspage... also I did plug the aux power into the card. What happens is as explained before, it gave the red flashing light, all my fans and everything turns on in the computer, there also is no beeping sound of any kind as well

OMG! I hope you didn't pay that much for it?? You could have gotten a Radeon HD3850, which is THE best AGP card ever made, for the same price! http://www.newegg.com/Product/Produ... If you pull the card & go back to the onboard, does everything work?

yes when I pull it out, I do get video again. When that card is in, I think my computer is not running like its support to. I think it doesn't boot because it makes no beep sound and everything inside is running really fast. Also, I bought the card for about 70$. I saw the ones on newegg but I haven't used the AGP slot in over 2 years since I had a PCI card in so I wanted to buy an AGP to make sure it worked, so then if there are problems, I can just return it

"but I haven't used the AGP slot in over 2 years since I had a PCI card in" You mean a PCI video card? Did you remove it & uninstall it's drivers before trying the AGP card?

yes i did uninstall the drivers for the PCI. the new card is an AGP. Also the computer will run on the on board video when the AGP card is not installed.
