I have a gateway with amd 1GHZ processor and 256mb 133 ram. i have it stripped down to bare bowns. cpu and memory. video is built on motherboard. i have tried everything to this pc and it freezes up on me. i have updated all the hard ware drivers, video. nic card, modem, sound card and bios. i have tried 2 new harddrives. one loaded with xp and one with win 98. still freezes up. i cant think of anything else to try except this would be a bad motherboard issue and needs to replaced. any suggestions??
