Did you try the usual new CMOS battery?
Hey Guys,I have a problem.
I have a HP AMD 64 pc ,at start there is no post and the monitor remains black,The fans run but the usb mouse has no power..
No error message or beeps but I haven't heard any for a while,Are they still used?
F2,F12,F10 fail to bring up bios.Monitor remains black.
I have reseated everything and put a new video card in.
I have tried to boot with a linux live disk but no improvement.The optical drive spins up ok though.
Have tested all power points and all ok.
It uses Am3 socket and the first pin hole has a black mark around it which looks suspicious.Would this mean that the motherboard has died?
Any help greatly appreciated.
