Light keeps blinking

Specs: xp, Celeron w/ 512 ram

We had a power failure last night and now my computer will not shut off and the power light and drive light keep blinking and it clicks all the time. I unplug it and then plug it back in and it does the same thing. Now the clicking has stopped but I still can't turn it off and the monitor is blank.

You have a damaged power supply, motherboard or something else. You probably need to take it to a shop for repair.

If you push and hold the power switch in for 4-5 seconds it will turn off.

When it starts up do you get any beeps? Do the numlock, caps lock, and scroll lock LED's flash? If so you may have a problem with the video adapter. If you have both on-board video and a video card try both.

If no beeps (and the damage was done by the power problems and not people fiddling inside the case) you probably have a bad motherboard and/or cpu. Maybe the power supply too. Try disconnecting all the drives and removing all the cards except video and see if anything shows on the screen.

There's really no practical way of testing the motherboard, cpu and PSU without swapping them out with known good ones and just seeing what happens.

You might try clearing the cmos with the motherboard jumper. People often think doing that is some kind of miracle cure--which it's not--but occasionally after diagnosing a motherboard as DOA we'll hear "Hey guys guess what? I cleared the cmos and it works fine now." So if that happens in your case at least we can say that was one of the recommendations.

emachines computers have power supplies that tend to fail more often than average.

The clicking may be your hard drive failing.
Check your hard drive.
