sometime last night the power flickered enough for all computers to shut down, 2 of them have no issues, but when I tried to turn my sons on the power light comes on and stays on (no flickering)and sounds like the hard drive is going a little fast. I have unplugged it the first time for 10/15 secs - no good then left in unplugged while ran some errands, tried it again and get the same..Monitor comes on and says "no signal", checked the monitor(works fine) Any ideas of what I can do would greatly be appreciated!!!!!!

The power flickering is not a good sign. A power spike or surge may have damaged that particular computer. The fact that the monitor error message is "no signal" indicates no output from the computer video card is being received. The behavior you are describing tends to be symptomatic of a computer damaged by a power surge. This can happen even if the PC is on a surge protector, especially if it's an old surge protector.

You can open the computer (make sure it's not plugged in) and check the capacitors on the motherboard. If the ends of the capacitors looked tented, or puffed out, or look like they're leaking, that would largely confirm it. The capacitors will by cylindrical and sticking up from the motherboard.
