Try connecting another monitor, if that still does not work, it is time to start checking memory and CPU and mother-board.
It sounds as if your power supply is ok, ie fans running on power supply and extra fan running.
Hope this helps

If your screen is black, but you have the power light on the monitor, then the monitor is at fault.

If you do not get the power light from the monitor, try plugging the monitor into another outlet. I've seen individual outlets on a power stripgo bad in these power fluxuation situations.

Try another monitor if both the above are unsuccessful.

The monitor, and the PC power supply are the first things to check / swap.

Both are stressed very heavily when the AC voltage drops.

If this is a common problem in your area, you should add a UPS unto your system, and plug the PC and monitor into the regulated output.
