When I push the button on my computer to turn it on, nothing comes on, no fans, harddrive, NOTHING. So, the button basically doesn't work.

When I have the power cord in and open the PC up, there is a light on the motherboard on, so the cord is fine.


Also, when I plug my moniter in, it knows that it's plugged in.

Can someone tell me how to fix the LED or whatever? I have a Dell Dimension Desktop.

Have there been any signs of abnormal behaviour prior to this happening? Freezes or restarts? Startup or shutdown problems? Slow operation?

It sounds like you have a hardware malfunction of some sort, and perhaps you should drop it in to a repairman if you're not comfortable with delving into its 'innards'.

I have 2 Dells with the same problem - one at work, one at home. At work they just gave me a new pc. At home I pulled the power for 5 minutes then plugged it back in and pressed the button once and waited. Eventually, the PC would start to start and then shut off - repeatedly.
I then pressed the button again and it booted normally.
Previously, I just kept pressing the button and waiting and eventually it started.

Not sure this helped...

i'll back up catweasles good advice here and say to you take it down to your nearest repair centre or pcworld store. im not 100% certain but my guess is that there is a power fault lying within the motherboard itself or in the wiring between the power switch and the board. i know this is going to seem like a very silly question but are you sure that the wiring for the power and reset/restart switches are plugged in appropriately on the motherboard. check your systems documentation and if possible go on the web and locate an up to date motherboard manual for your specific board and machine.

why are u not calling dell tech support?

good question but i can understand the reasons for not wanting to contact dell tech support. first is the extortionate costs of the premium rate phone lines and the service is in my opinion not what it ought to be.

Main reason I'd suspect is that the Warranty has expired

how very true, but even so they should be able to advise and maybe make a telephone diagnosis of the fault. it may be simple it may not

but either way it's gonna cost you if the Warranty support has expired

true, worth a go tho.:-|
