I recently upgraded to a Albatron Geforce4 4200p Turbo. I haven't overclocked the card at all, so its at whatever it's default settings is. I can surf or use my computer fine, but when I go to play any games after a pretty much random period of time it will hard lock and I'll usually get looping sound in my speakers. All of my drivers are up to day, except for my soundcard drivers which are a little behind, I can't seem to get the newiest Gametheaterxp drivers to install. Only thing I havn't tried are to flash the bios on the videocard and/or lowering the speed below default on the card (assuming it might be overheating). My specs: Geforce 4 Ti4200p turbo 1.4ghz thunderbird 256 megs generic SDRAM Gametheaterxp soundcard Amptron M1l80 motherboard Enermax 300watt powersupply I don't have much experience dealing with this, I'm usually a couple of generations behind on videocards, any help would be appreciated.
