PC won't power up

Check to make sure the power switch on your surge protector hasn't been reset - also check the connection at the back of the computer -

Have you checked the fuses in the plug and on the fuseboard in your house?

More than likely your power supply got fried from a power surge during that storm anyway. You'd be surprised at how worthless most surge suppressors are these days.

Test your PSU or replace it if your power supply units fan is not working your PSU is faulty

One bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect/ boot up a computer hard drive

Test all leads that attach to your hard drive including electrical extensions,IDE,SATA

the leads from your MOTHERBOARD TO YOUR HARD DRIVE make sure they have a secure connection and are not faulty or just replace them they could be faulty

make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty even the electrical extensions or just replace them they could be faulty a computer needs its connections to continue its cycle and have an end so any faulty leads will end up with a computer error

even something as small as a faulty electrical extension or fan lead can cause you problems

computers need all of the data and electrical current to travel through every working device and to have an end to be able work properly

motherboard and a hard drive any leads between them will fail before your motherboard or your hard drive if its a flat ribbon 40 pin type IDE replace it this will be the first to fail

check all electrical power input and extensions make sure they are securely seated even the cd/dvd floppy drives need to have current go through make sure these drives are working

also check the Cmos battery and computer RAM modules make sure they are securely seated with no dust built up or in the sockets on some motherboards cmos batteries are soldered in

hope this helps you

Hi....If the computer will not start and you hear no fans or other electrical sounds chances are the power supply has failed. If you had an electrical storm that caused the blackout and did not have a surge protector power strip it could be much worse. Check the power supply first. You can google for help in testing that supply. Good Luck Hank

Turn the monitor off.
Unplug it from the AC power.
Reconnect it, turn it on, and see if it returns to "normal".

Do you have house-insurance that covers electrical damage from lightning/thunder storms?

you need a power supply. That is where the fuses are and you should not replace them.
The Power Supply should be replaced.

First thing to do is try to plug the pc in another wall socket to see if it goes on, If not, the MB could have gotten fried, even though the other plugs seem to work. Hopfully you just need another surge protector as that could have gotten damaged.

check your keyboard connection (unplug and plug again). If not works try another of same type.

Hope is last to dye. Be calm and contact the technician with best references or Authorized Sony Service. If you need more info please advice
