A friend of mine bought some of my old parts a month ago (Duron 800, 512 RAM... etc) and went to buy a motherboard on his own. He goes out and buys a refurbished Abit because it was only $40. Turns out the keyboard/mouse ports didnt work but with USB peripherals that wasnt a problem. After attempting to link up two dial-up modems together the computer began running extremely slow (10 minutes to boot windows) then after repeated attempts to fix it, a Boot Block CMOS Checksum error occured on startup. And would not let the computer proceed. After countless days of research and troubleshooting he went out and purchased a new MSI motherboard. To no avail, the MSI still didn't save the CMOS settings but did however let him boot the computer. After the CMOS error comes up, he has power off, reset the jumper or else he won't get video. When he attempts to save in CMOS and exit, the computer fails to power on after powering off. The battery checks out, no viruses found, tried new power supply.. other video cards, modems. Anyone have any ideas?
