Having trouble with my computer,after a powercut yesterday i went to switch on the computer?
Answer:
Yes, hopefully your power supply took the brunt of the damage. Don't worry, they are cheap and easy to replace. Just open your computer up and take the power supply out. (It will be towards the back of the computer, a big metal box with lots of multi-colored wires coming out of it.) Take it to a computer shop and tell them you need an identical one. Then put the new one back in the old one's place. It's pretty much just that simple. Assuming you don't have any fancy gaming computer, your new power supply shouldn't run you more than $50.
chek all connections. surely some loos connectionss.
It sounds like it could be the power supply to me too - normally if it's the hard drive or another component it would at least turn on and give you an error message. Be warned though there could be other hardware damage as well if the power cut was significant enough!
Open your case and remove your modem(where you plug the phone cord in). It's possible the modem is shorting out the motherboard. If this doesn't work then the cheapest thing to do is replace your power supply. It's either the power supply, the motherboard, or the processor(least likely). Good Luck HTH.
Yep im gunna say that yout power supply is toast. Ususally you can sniff where the power cord plugs into your computer and smell an electrical burning. If so then that's it.
The power supply acts like a ciurcuit breaker would for your house. It regulates the power entering your computer and conditions it.. and if there's a surge or a spike then the power supply will take the hit and your computer components should be untouched.
You can get a power supply from tigerdirect.com Id reccomend a 600w at least. :)
If the light is on it is unlikely its the power supply. Try unplugging the computer and on the back where the plug goes you will see a little red slide swith for voltage selection. Slide that selector to the right side and then back again. I dont know why but sometimes that works.
If the power supply fan is working then, it may not be the power supply. If the light is blinking, you may have to turn the computer off. Unplug the power cord. Press the power button for about 30 seconds. Plug your power cord and turn your computer on.
I hope this helps you. Good luck.
It is possible that it is the power supply that could be damaged. if you left the plug in and power on (at the socket) when the electric came back on. becasue when the power comse back on after a black out there is a surge in teh electric and can damage some electrical components.

Are there any beeps when the computer comes on, the number of beeps can tell you whats wrong. just type the amount of beeps into a search engin, (eg 3 beeps on startup) and you will have a clearer (sort of) idea of whats happend.
if your computer was plugged in at the time of power failure, it may have blown out your motherboard from a power surge or it is your power supply
I've come across this sort of thing before, both personally and online when researching what might be wrong with my PC, where the PC can't immediately be turned on after the power-supply is connected, but the standby power was being supplied and it was able to be fired up after maybe a minute or two.
In all cases, the problem has been a combination of the motherboard which is very careful about the voltages supplied by the PSU before allowing the system to boot-up, and the PSU which is supplying out-of-spec voltages on the standby power rail for some period after it is turned on. The cure for the problem has always been a replacement PSU, or quite simply being patient until the voltages settle as there have been no indications once the PSU is operating normally (fan spinning, etc) that there is anything wrong with it.
You could turn the power to the PSU on and leave it for ten minutes and then try powering-up to see if that works, but it does sound like the power-surge which followed the outage has harmed the PSU in some way so it would be wise to replace it.
One thing I will say is please spend the £5-10 or so it costs to buy a decent surge-protected 4-gang extension lead to run your PC, monitor etc so that any future outages and subsequent power-surges will be absorbed by it rather than your PC. That is also probably the best computer hardware advice I can give for anyone else who isn't already using one.
Check all connections. When you turned the plug of you might of knocked a wire or something because some of them wires come out really quick.
