When I first turn my computer on, the power light will flicker for literally half of a second, and then turn off. AT that point I cannot turn my computer back on from the main on/off button. It must have all power removed, ie, lead removed from back or plug switched off at the wall. Then the computer might start perfectly. But this problem is continually happening and I dont know why.

If your computer runs after you do all the replugging in and stuff then the power supply is still good. If after you start the computer and then later on the computer turns off then definitely the power supply.
My mission now is to call all the dummies to list your computer brand and model for problems. Anyway, I would try a different power cord to the computer. Then if that don't work, then take it to the computer shop. You could replace your power supply yourself. Go to cnet.com and I have seen the video and they show you the basics. It is real easy. Of course, you do that if that is the problem. Check out first what a power supply will cost before you take it to the computer guy. Then you can see if you can afford the labor. Also take your side panel off and mark the computer power supply to make sure if you do get it repaired, that it is a new one, and maybe not just a loose connection he tightened up to make it work right. Then he could charge you for a power supply and you would never know. Most people do not take the covers off. Go to BELARC to see what is inside your computer.

Go for the easiest answers first, like moving to a different plug...
If that doesnt work you may need a new powersupply.....the bad thing about that is, if it is the powersupply, they tend to burn up the motherboard and everything attached when they die, so hopefully its not that.....I had a pc recently do the same thing, I lost the power supply. If you dont have anotherone to test with, then take your pc to the Geek Squad at BestBuy, or any local computer store, because this is more likely a hardware problem..

Yep, go for the easiest solutions first. I had an old computer, and the power supply had failed after some time.
New computers can have bad power supplies as well, since they are usually obtained by bulk purchases from companies overseas.
Bad power flow can cause your other components to not work properly, and even fail.
If you don't have a spare power supply to change out, you can pick up one from Fry's pretty cheap, or take it to Best Buy or CompUSA and ask them to check it out.

First of all I would try in another power supply, it may be failing, it sounds like the chip-set is not receiving the "power good signal" from the power supply, if no power good signal is not received then the system will shut down, please do NOTattempt to open up the power supply, there are capacitors inside, that hold onto many 1000s of volts, of which if you accidentally touch one they can unload those volts straight through your body, try a power supply in you know is good, borrow one if you have to, see if it cures the problem.

its possibly the power supply, but i would bet its the motherboard or cpu. find out the maker and model of the motherboard and if there are beeps look at the manufacturers website for beep codes.
it could also be the processor.
