Solved My Dell computer will not come on. PSU won't work either.

January 23, 2014 at 11:30:10
Specs: Windows 7
My computer (Dell) will not come on at all. The green light is out all together. Tried plugging the computer into another PSU and still nothing. I am wondering when the electricians were doing some electrical work at my place and caused a electrical blow out shortage in my unit, would that cause my PSU or Motherboard to go out. The blow out caused my Direct box to blow out, DVD player and a little boom box.

A serious line (mains) voltage surge could fry just about anything.. - even with a surge protector… Particularly if the surge protector has had a hit already - even a minor one.

I know of one modem going out permanently after a lighting strike - and it had a surge protector in-line too!

Surge protector generally are best replaced after even a single hit - particularly on the domestic versions. More heavy duty/commercial versions may stand a few hits - before they too ought to be replaced. Some of the domestic protectors used to have a warning to this effect!.

If the situation was caused by someone working on the electric supply in your house…. then possibly you have a claim against them, and for some financial recompense - to cover your losses (they will have - or ought to have - suitable insurance)? They can/will counter you ought to have powered down/unplugged all sensitive kit of course, but who know you may be lucky and at least get recompense for a replacement computer?

"Tried plugging the computer into another PSU and still nothing"

You haven't supplied enough details about your Dell computer or the PSU. I'm guessing it's a desktop rather than a laptop. Did you remove the suspected bad PSU & install a known-to-be-good PSU in it's place? Are you sure everything is connected properly? Did you have the Dell plugged into a surge protector?

Also... There "may" be a fuse (glass or ceramic) inside the Dell... There used to be in days of yore... Have a look-see?

THIS MESSAGE IS FOR RIIDER: It's a Dell desk top and was plugged into a surge protector. Tried a few new PSU's and the computer still would not come on. Everything was connected correctly. I wondering when the electricians did work with my house breaker panel outside and caused an electrical blow out of things in my place if this would cause my motherboard to also blow out. Everything was connected ok with my computer. Again, tried plugging into another outlet (socket) and wouldn't come on. Computer guy tried different PSU's still wouldn't work. Now he tell me the mother board is gone.

THANK YOU. THE ELECTRICIANS NEVER TOLD ME THEY WOULD BE WORKING ON MY APARTMENT UNIT, NOR DID THEY TELL ME I NEEDED TO TURN OFF ALL THINGS LIKE MY COMPUTER, TV, DVD BOX, ETC. THEY CAUSED MY CEILING LIGHTS ALSO TO BLOW OUT. THANKS AGAIN BECAUSE I DIDN'T WANT TO JUST EXCEPT THE COMPUTER GUY'S ANSWER SINCE HE'S A FRIEND OF THE ELECTRICIAN.
