My computer died yesterday when a picture fell off the wall and hit the outlet that the power strip/surge protector was plugged into. We've been trying to diagnosis what might be wrong. It 'seems' to boot, but nothing shows up on the monitor. I swapped the monitor to Emily's computer, where it works fine. I pulled and reseated my video card several times. I disconnected and reconnected all the cables. I took an old video card and replaced mine with it(an old 64mb card).
Nothing yet has worked. We previously noted that the power cord connection to the power supply was sensitive and the computer would reboot if you bumped it. I replace the cord with an alternate cord. I'm thinking of swapping out the power supply for one of the others to see if maybe that is kaput.
