Since I received no suggestions from the folks who read my request for help I managed to find quite a few older (2-3 years) posts concerning this problem. I unplugged the power cable to the tower, opened up the case and cleaned the inside as best I could. After putting everything back together, I rebooted and pressed the F8 key to control the startup.
The machine managed to get to the desktop allowing me to go to the control panel and change the power save mode to "never". With any luck at all, this has solved the problem
I'll be back if the computer
