I recentley moved a computer to another workplace. After connecting it up and turnig it on, the monitor will not display anything. I tried the monitor on another computer and it works fine. Replaced the monitor to the previous computer and got no display again. Could there be a problem with the video card and if so, how can it be checked. Any chance the cmos battery would be involved? Noticed that there were two ‘beeps’ instead of the one ‘beep’ I’m used to hearing when turning on the computer. All help/advice is highly appreciated…
