Computer Issues

This past week, the computer stopped working and smelled like burnt electronics. Three possibilities were considered--a failed power supply, a broken power-on switch, or a ruined motherboard. The power switch checked out okay, and the power supply seemed the next most likely cause of failure. A new power supply did not help, but I'm glad I replaced the small unit with a larger one. A new motherboard and processor have been ordered and I hope will resolve the problem. In the meantime, I'm trying to use a new notebook with only a touchpad. It works, and that's all I can say for it.
