PC won't boot at all after thunderstorm

December 28, 2010 at 07:03:53
Specs: Windows 7, Athlon 64 2.7 Ghz/2.5 Gb RAM
I had my computer turned off without a surge protector, then after a thunderstorm it didn't turn on anymore, no fans, no lights, no nothing (it also damaged my external ADSL modem, along w/ many other things -.-")... ..so i assumed it was the PSU...i bought a new one and installed it but it still doesn't work... there's still no lights or sounds or fans. i tried disconnecting hard disk and cd room, and clearing CMOS..still nothing. Can anyone help me out to find out what is my problem?

If you correctly installed a compatible power supply and that didn't solve the problem then the motherboard is probably also damaged. You did verify the voltage setting on the power supply is set right, if there is one.

When disconnecting the old PSU did you observe any discoloration around the power connector to the motherboard?

You may be able to recover files from the hard drive by slaving it to another computer.

The motherboard is probably damaged.
The only real protection from lightening damage is to pull the plug. Turing the power off on the computer won't help much. A surge protector will help but may not be enough. Turning the power off on a power bar is also inadequate.

Lucky you were not online at the time. It could have been you that isn't booting up.

I agree that a surge protector or a power strip may not work. They tend to prevent a lot of problems in this situation but lightning is static electricity and can travel over air, plastic, moist wood or just about any surface. Only a complete metal cage that can survive the energy could prevent it.

You are better off with some sort control. Many strips and ups's offer a policy to pay you in the event their equipment fails to protect. It is well worth it to use them.

Why did it take me over a year to phone in a problem to ATT?
