alright i fixed my problem

i downloaded some program called Everest Home Edition which is sorta like that sandra program that displays into about your computer. for some reason it said that AGP was disabled on my motherboard but yet in the bios it said that it was enabled. Everest gave me a link to download newer chipset drivers so i installed them. When i restarted, Everest showed that AGP was now enabled. my card works flawlessly now

thanks for all your help
