I have been asked to try and fix an old Celeron PC running Windows 98. It boots up OK, can hear one beep for the POST, but nothing on the monitor except 'no signal'. Have tested the monitor and VGA cable on another PC and they are working OK. Have also reseated the RAM and cleaned out a decade of dust, tested the power supply, all OK too.
So I'm assuming the onboard graphics have blown (there's no separate video card)? If I could get hold of an old PCI/ISA video card then I could fit this instead, but without a display working, how can I disable the onboard graphics?
I'm assuming that even if I boot it up in Safe Mode, the monitor will still not function with the basic Windows drivers if the graphics chip has failed? Is there any way around this?
If I remove the CMOS battery, will this reset the graphics to work from a separate card maybe?
