im attempting to make a small upgrade, instead of doing a complete overhaul on my system. right now i use a athlonxp 2800+, gig of ram (pc2700), and a geforce 5500...ive tried a geforce 6600 and radeon x850 on my system and both of them cause huge video problems. I have a 500watt power supply and i reformatted before each install, my epox 8kraipro has one small little bios update that doesnt help, and ive tried multiple different drivers. It seems to be that this motherboard im using (Epox 8KRAI-PRO) just will not allow any of the higher end agp video cards work, im assuming something with the voltage. Does anyone know a way to fix this? or if i cant, is there any motherboard that would take my athlonxp2800+ that also has a pci express slot? or do i HAVE to upgrade to a amd64 to get one - thanks
