A couple questions...

- how do I reset the CMOS?

- How do I measure the house voltage?

And by the way, the cost was about $40 (give or take) at each of the places I took it.

Thanks in advance.

Hi

I replaced the PSU, and still the same problem.

How could the voltage of my house do this?  Ie. everything else in the house works fine, and this problem seemed to get worse as time went on.

You can measure the house voltage with a voltmeter.
With the powerpoint turned off...
Unplug the the computer plug from the wall.
Put in a double adaptor.
Plug the computer plug back in.
Make sure you have the voltmeter set to the correct scale and push the probes into the spare side of the double adaptor.
Turn on the powerpoint at the wall.
Check the voltage & compare the reading with what it should be for your area.
Then turn on your computer & watch for voltage fluctuations on the meter.
(All of the above terms may be slightly different for you because of your local language)

Just a note, if your supply voltage is supposed to be 115 Volts but you are only getting 100 Volts, your lights will still work, your toaster will still work, but your computer might not.
