My computer will not power up -- I mean it won't even turn on. When I hit the power button nothing happens. Does this mean that my power supply went kaput and needs to be replaced or could it be a more serious problem???

Probably is the power supply. Yes it could also be the motherboard fried. Probably not the cpu; they are very durable and usually motherboard will go long before the cpu is damaged.
Best way to find out is to try another power supply and see if it powers. If you don't have one lying around or that you could borrow and you have to buy one, be sure and get one that has much more wattage. Not only may low-watt psu have been what caused your psu to go bad in the first place, but if you decide to upgrade your pc later you will already have the psu.

First thing I would check, Is it plugged in? I remember trying to start a lawnmower for a half hour until I remembers I took the wire off the spark plug. Do you have power coming from the wall outlet to any other source?
Changing the power supply is fairly easy. Open the case, locate the power supply, label first and then unplug all connections, Take the power supply to Best Buys, or any other computer retailer. Get a new one the next size bigger, take it home and do everything in reverse. No problem.

Happened to me once. I have a dell gx100 and I unplugged it during a thunderstorm, (as I always do) when I tried to start it back up, it wouldn't start. The power light on the front flashed amber. Someone told me the motherboard had died. I went out and bought a used power supply and solved the problem. That was about four years ago and it's still going. Before going into your pc though, I would do as everyone says....check your connections first

Here is a link to a page all about power supply pin outs. If you jump pins 14 and 15 on the big 20/24 plug, it should at least try to start. if it doesn't, then it is probably bad and needs replacing.

Before you try the above, unplug you system, let it set for a few minutes and plug it back in and try to start it. If it does not start, go ahead with the above instructions.

Hopefully it was just the power suppy b/c that's cheaper to fix.
And it sounds like it's most likely that.
Otherwise your fan on the p.s should at least run.
If your not going to do it yourself take it to a good PC repair specialist.
Power supplies aren't too much and labor will most likely cost u more.
Just get prices up front. If they're fair you should be able to do it for well under $100.
Good Luck!

There is a complete check list and How to for power supplies on my web site....

between the answerers above claimed a pc in use is like having on a 40watt bulb. properly, if your 40watt bulb attracts approximately one hundred fifty-200watts, i might heavily ask for my a reimbursement. i've got checked quite some the computers i've got owned with a power-intake meter, and that they have an inclination to apply between one hundred fifty-200watts. power is measured in watt/hours, so a pc like this left on for an hour might use 200watt/hours of electrical energy. those computers have had processors interior the only million.5Ghz-2GHz selection. while you're making use of a very speedy processor and additionally you do countless gaming with a posh snap shots card outfitted, you may desire to in all hazard stick yet another a hundred-150watts onto that. A CRT computer screen makes use of a honest quantity of power too - my previous 15inch one averages approximately 80watts. liquid crystal reveal video reveal units tend to be much less power hungry than CRTs. Leaving computers on whilst they are no longer in use isn't in basic terms a waste of money yet for sure additionally an uneccessary contribution to international warming. yet another element to remember is that digital factors have constrained lifespans, oftentimes measured in tens or hundreds of hundreds of hours. Capacitors (you will discover countless those on your power furnish and on your motherboard) have shorter lifespans than many different factors, appreciably shorter in the event that they're run in heat or warm environments.

That is what I would start with. Smell the power supply. Does it smell like burned wires? If so, that is it. Replace that first and pray that nothing went with it.
