Why my computer can't power up?





jake1496
Hello everyone! I bought a Lenovo PC from ebay.com and a dell PC from sourcinggate.com three years ago but hadn't used them since the last year. Then I found I even can't power them up a few days ago. Who can tell me the reason? Thank you!

I suppose you mean that nothing happens when you press the power button.

First off, check for obvious problems like damaged cables, etc. Then, check the inside of the CPU case to see whether dust is blocking any fan vents or anything. Another culprit could be the PSU.

If the computer doesn't power up at all, it usually suggests something not software related.

Simple question, usually the first to ask:

Is there a switch on the PSU (near where the power plug gets plugged in)? If so, switch it and see if it powers on. What happens when you press the power button? Any lights turn on? Plug something else into the outlet that you plugged the computer into.

Work your way from the walll to the PC.


1. check the outlet:
* does it have a switch? Check if not switched off.
* if you plug in another appliance.. like a radio or even a lamp and see if it receives power.

2. check the cabling to the PC.
* are you plugging directly into the wall socket or are you using some kind of surgemaster,

* check if the cable is secured into the Power socket of the PC.

as said by Diablosblizz:
3. is there a power switch on the back of your machine. (mine has one)

IF ALL the above is OK..

4. check the Power Unit of your PC
* check if all the Power cables are secured on and to the MoBo.

I would be inclined to say that anything other then the above would be a suspected hardware issue.

anybody would like to add something?


ps: hope this helps you out, keep us posted
