I have an AMD Athlon 700MHZ machine with 128M Ram and a GeForce256 video card. My system will randomly freeze. The keyboard and mouse lock up and because I have an ATX motherboard even my power switch doesn't work. (I can hit the reset to restart). I have reformatted my hard drive and re-installed Win98-SE and did not install any 3rd party software except drivers for video, monitor, and sound card. (Vortex 2) but it didn't help. All power saving is off as well as the screen saver. I have downloaded/installed the latest video card drivers. I tried disabling external cache then internal cache but the system would still freeze. I am thinking that one of 3 things may be the problem. My motherboard, CPU, or video card. If anyone has any ideas where I should start please let me know. Thanx in advance -Tony T.
