Hi,

History of problem:

I formated computer (HP Pavalion Desktop).
When I restart computer - computer come to first screen before boot and not response to any signals (f2, f10, ESC, etc..)
I take out motherboad battery return after time back and power computer - result : as before
I disconnect wires of hard-disk and insert livecd UBUNTU to cd and power coputer: result: works without hard-disk.

What is the root of problem:

hard-disk broken?
hard-disk wires not working well?
BIOS?
other reason

How can I fix the problem?(Buy new hard disk etc...)

Thanks,

Yosef
