My brother has a p4 3.0 ghz computer...It has a 478 board. A few days ago the computer shut off after a storm and wouldn't even start up till he fiddled with it awhile. (wasn't any close lightning at all) What's happening now is that powers on but nothing at all shows on the screen except for the "check your video cable" message. (No bios screen,ect) Same thing is happening also on his other computer..
The motherboard was replaced and that wasn't the problem. The ram was taken out and checked but also doesn't seem to be bad. Same with the PSU...Can't check the cpu since we can't get anything on the screen. The cmos was also cleared and the drivers were good for the new motherboard. Don't think it's the video card since its happening on two computers.
Has anyone ever heard of or had this problem?
Any info or suggestions on what to do would be greatly appreciated...
 
If its the same monitor, then its a monitor fault.

Make sure that you test the video cards, its not uncommon for two things to fail after a storm. When you take the memory out of the motherboard and start the computer up, does it give out one long, continuous beep? If it does, then its the memory for sure (I said that before I realised that you had replaced the mobo, but still do it). But check out the video cards as well, like I said its not uncommon. Then check out the monitor.
 
We had a problem with that in my research lab. Turns out someone was stupid and plugged the monitor cable into the wrong slot in the back, ie not the video card and hence that message kept popping up. I fixed it :-P
 
Two different monitors, same problem....Replaced the one motherboard and rechecked the ram on it so figure its not that unless all the memory on two computers went bad. Tried new cables for the video cards but same problem still...Same plugins on the back as they always were so don't think it's the wrong slot. Will have to ask him tonite about the beeps tho....
Hard to figure out problems when it won't post/show anything....
