there are a few things to check first.....................
1. check the fuse in the plug,it could be as simple as this
2. check the switch at the back of the p.c,not all p.c,s have these so some users dont recognize them
3. when you turn the p.c on ,is there any lights or any kind of noise or sound,if not then its your psu(power supply unit)
most psu,s are quite cheap to buy but you need to make sure you buy the correct one,it may sound like a big job but its actally one of the easiest p.c tasks to perform
open the case to gain access to the psu and after unpluging all of the power leads from all of the components(hard drive,dvd-rw,floppy drive,graphic card,motherboard)unscrew the psu from the main chassis of the tower
before discrading it check the power of the psu,it will be somewhere between 250w to 600w,but its more than likely to be around 400w,then write this down to take to your local p.c shop
then its just a case of when you have the new psu,just do the whole process again,except in reverse
and thats it...job done
good luck

Common Steps to Troubleshoot Power Problems:
1. Ensure the power cord is plugged in.
2. If using a power strip, ensure it is plugged in to the wall outlet, and that the computer plug is plugged into the power strip, and that the power strip power switch is ON.
2A. You can always confirm that the outlet has power coming from it by taking a table lamp and plugging it into the outlet where the PC is plugged in. NOTE: Electrical outlets in some older houses were designed to supply the upper plugs with electricity only when the light switch for the room is in the ON position.
3. Check where the power cord connects to the back of the tower, it could be loose.
4. If you get this far, check the circuit breaker for that room. It may have tripped. Some rooms operate on more than 1 circuit breaker, so check them all.
5. If you have accomplished all the above and still have no "power to the tower", then you probably have a blown power supply. Get it checked and replace if you want to.
6. This one you will need a computer repair persons assistance. Check the motherboard at the location where the wires coming from the power source connect to it. If its browned or charred, your motherboard is toast.
NOTE: Some of these steps sound like their intended to make a person sound stupid. they are not. You would not believe the number of times I have found that, if they'd just have plugged it in.......*smile* It happens to the best of us. Good Luck!

1. Check the outlet has power (use a light)
2. Check the cord connections are good (try a different cord)
3. Check the switch on the back of the tower and make sure it is on.
4. If plugged into a power strip make sure that is switched on or bypass it temporarily (plug into wall).
5. If still no power, could be a bad powersupply inside the case or a bad motherboard, or a bad case switch.

It sounds like you have a bad power supply. I have put three in my computer and I have it on electrical spike control. You will probably have to have a professional install a new one ($30 for the part $30-$75 for labor depending where you are). While you are there purchase power protection (not a simple power strip, it should cost at least $50).

If the monitor is OK and it's taking its power from the same power supply then check that the plug into the PC is fully home. If you are using a separate plug to the PC check the fuse, otherwise sounds like a PSU problem in the PC.

Since everyone else thinks you are a total idiot and dont have it plugged in, I will give you a better answer.
The power supply likely has gone out. That is not expensive to fix. If it is not the power supply, it could be the motherboard, which is a bit more expensive.

The power supply likely has gone out. That is not expensive to fix abou £10 - 15 max if new. If it is not the power supply, it is most likely to be the motherboard and they are expensive by comparison - £ 60+ depending on your requirements.

make sure the cord is pluged in, if it has a switch on the back of the tower where the cord plugs in, make sure it isn't fliped off. I is on and 0zero is off. if neither are the source, then you probably have a bad power supply.
real smart VIOLATOR you have been reported. there is no reason for that. you're not cool for doing do. i reccomend everyone who reads this to report him..
