My computer doesn't start. When I press the power button, nothing happens. I checked that all the cables are plugged in and I even tried switching the outlet, but it didn't help. What could be the matter with my computer. Could it be a failed power supply? or is it something else?

Thank you for your help.

If you get no power leds or indicators, or if you check the fan when the computer should be on, then yes, your power supple may have failed. Also try plugging in the computer in another outlet... I had a user upstairs who's monitor would not power up, and it was a bad outlet.

Double check all connections on the motherboard. Make sure they are not loose. Is there an external off and on switch at the back of the case? If so, double check that. If these two things do not work, take the front of the case off. Try turning thecomputer on again. Sometimes the on button does not make contact with the switch. If you have verified the above, than the last thing to do is replace the power supply.

Is there a rocker switch and a slide switch in the back of your computer? The slide switch should be showing 110 not 220 and the rocker switch try it both ways. If this dose not work and you still dont want to replace the power supply. You can buy an axt tester for 12 bucks and if it says its bad well power supplies are cheap too.

try check if the power is on by check the power fan.
If it is on then not PWS.
Then if PWS okay, check if there is a beep when it boots.
If it beep twice or more check your VGA card or memory.
If there is no beep at all and the monitor is standby then it probably your memory..
try to switch with other memory module

hope it's helps

Have you tried replacing the power cable. You can use a cable from anoter computer to save you buyin one. If this dosent work then try a different outlet. If this still dosent work then you will probably need a new power supply.
Hope it helps..........

It could certainly be the power supply, since you say that "nothing" happens. But it could also be something simpler. Newer computers use a soft switch - the switch goes to a circuit on the motherboard that does suppossedly 'smart' things, such aswaiting ten seconds before powering down. The connection on the motherboard may be loose. You may also have a bad switch - unplug its cable from the motherboard and use a cheap continuity tester to see if it's closing when you press it.
