I have an Asus A7S333 Motherboard, AMD Athlon XP 2100 Processor, running Windows XP. My computer will crash at random times, somtimes after its been on a day, sometimes for a couple of hours. The comptuer just shuts off, the power light on the motherboard remains on, but i must unplug the computer from the wall before it will turn back on. It is definately not a virus. I replaced my hard drive. I replaced my heatsink and fan to a more powerful one, to assure it isnt a heat problem. After it crashes, I unplug it, plug it back in, boot it up, and i get a Invalid System Disk error.(only after it crashes) I reboot again and it boots to windows fine. Prior to this problem, I ran windows XP for 9 months with no problems. Any comments or suggestions would be appreciative.
