I have a Dell Dimension 2400. I believe it was hit by lightning just the other day. The machine will not power on at all. I replaced the MOBO with another identical board and it will power up however I get no video and the Dell ABCD lights on the back, none are lit except for the D and it is orange. Also the Power Light stays lit constantly orange and the HD light doesn't come on at all. I have replaced the RAM, Power supply, CPU, MOBO, HD, CDROM, Dell power switch and there are no PCI, AGP cards at all. I'm almost 100% sure that the board I replaced the bad one with is good but I'm not sure at this point. Any help is greatly appreciated.
