Computer shows no video

[max347]

I am hoping this is a simple problem, ive taken this apart about 5 times so far. Anyway, here goes-

I built my brother a comp recently, and it is not my first build. Turned it on, installed vista, set the whole thing up and was running fine. I moved the comp upstairs. I came back the next day, booted it up, and got an error message. Stupidly, I did not write it down, figuring a reboot would probably fix it. I tried to reboot, only to find that the computer stopped outputting video.

Both power connectors are hooked up. Video card has power. All fans (including cpu fan) spin, hd spins, case lights turn on, optical drive spins, psu fan spins.

Am I looking at a dead cpu? The psu is new, and although it could be that, I highly doubt it.

Other info-
cpu/hsf both cleaned with rubbing alcohol prior to applying as5. The motherboard light turns on and so does the cpu fan, so im thinking is unlikely for the motherboard to be toast.

Please lmk if you guys have any ideas. Thanks, Max

without knowing the error message or hardware, hard to say. try swapping video cards and see if that one will work in a knwon good system, but we're blindly guessing at this point.

Sorry, yes the card works in another comp. Hd works in another comp, swapped ram, all good ram, optical drive was known to have problems, but I did not consider that to be significant to the video issue. Thanks

Problem solved, if anyone was searching this thread, dead cpu.

A couple other things to check-proper thermal grease application and both 12v lines into the mobo.

Thanks

Sorry to hear about your dead CPU, but thank you for giving us the outcome! My friend has a PC that another friend built for him....he went through 2 mobos and tried several video cards, but still can't get any video. He's having a tech store check it out on Wednesday.
