Here is something to try, after an electrical storm, sometimes the bios get messed up, there is a little battery inside the puter on the motherboard, take it out, wait a minute and put it back in, now youre bios is reset, try to turn it on.
Most of the time that little light is weak or blinkin, its or the bios, or a memory problem.
So if the battery thing dont work, try to take out one of the memory cards and try again.
Hope this will help ya
