Ok I have a K7N2 Kelta series mobo with an Athlon XP2400+ cpu, one stick of pc 2100@133 fsb 256m ram and a stick of pc 2100@133 fsb 512m ram, with a Nvidia Geforce 5200 vid card. My problem is while im playing my game Red Faction the whole comp will just freeze up and I have to reboot. It does not happen at a given time it is random. I have replaced my hdd thinking that could be it but it did not help I have also noticed the fan on my agp chipset was burnt out so i replaced but had to go to a smaller heatsink in the process. If anyone has any ideas what could be my problem please help me resolve this matter. Thank you for your time.
