Power button, button electrical path, power supply. Do any fans work? Jumper electrical connector to try to start if and I say IFFFF it is the kind that can be jumpered.
It is a desktop pc, fans are working and I removed battery on motherboard for at least half hour.I don't know what you means by "jumper". Pls. explain

We have a desktop 300 GB HD, OS W7. After receiving an email first had a screen with a lot of horizontal lines going on, thereafter screen went black. Tried to restart normal and with F8 even F2 but screen stays dead, machine fans working. Tried another monitor an other VGA cable and another keyboard. Then opened pc case and took out battery for at least half hour. Nothing still not even a light signal on keyboard. Any suggestions how to solve ?
thanks,

A jumper is a small switch which is toggled by "jumping" (establishing a connection) between two pins. The little bit which provides the connection allows the circuit to "jump" across the pins, so it's referred to as a "jumper."
With the switch "jumpered," the device is set in one state; with it not "jumpered," the device is in the opposite state. In the old days, when you had two physical hard drives in a computer, the one you were booting from was jumpered to be the "master"; the other one would have to be set as the "slave."
