Re: a few display questions
clear your cmos, if you have onboard graphics and an addon card, then remove the addon card, and try the onboard just by itself.
i got a few questions first before you do that: When you start your computer, does it beep? also, do the fans and harddrives spin up, and the lights light up?
or when you press the button does it sound normal, just no display?
(things to check, try all available monitor hookups on the back of the pc, if there is more than one, then just moving the cable might solve the problem)
or when you press the button does it beep at you?
(if so, please tell the number and frequency of the beeps, EG: 3 short beeps then a 1sec wait and 3 more short beeps, repeats till power off)
or when you press the button does it not do anything at all?
(your powersupply may have died)
and last but not least, what are the specifications of the pc, eg: mobo, ram, psu, and cpu?
