While I was using my Gateway, my monitor screen went black. I ruled out a problem with monitor. Works fine with other computers.
Next , test was to turn off unit and re- boot. The unit lights lights up.
lights on motherboard lit. Wife light blinks properly. Fans run. This is a Gateway tower, model835GM. Nice machine. 2.6GH intel Duo Core 820 processor. The bios seems to be working because it beeps once when powering up unit. Installed in the unit is a NVIDIA video board. This video card worked when installed for a year or more after installation. The Monitor shows no signal when Monitor is connected to either the NVIDIA video card or the intergraded monitor connection on the mother board.
Can anyone give me the next step how to check for what the problem is before I take the unit to a repair shop? I have no test equipment available.
