case with my computer g845 display is that
1) when monitor disconnected shows no signal means monitor is ok.
2)keyboard and mouse work with other pc also power light and hd lights are working
3)I also tried to clear the bios by removing the button cell on mb and again putting after 1 min.
4)supply also working ok as fan of smps and processor working ok.
I think some problem with motherboard but no beeps are coming so its hard to locate the exact problem.
can anybody give the right suggestion to solve the problem ?
