I've just been given a Compaq Presario 5441 but, when I switch it on, the monitor light stays orange for about 5 minutes then goes green with the following message : If you can read this message, Windows has successfully initialised this display adapter. To use this adapter as part of your Windows Desktop, open the Display option in the Control Panel and adjust the settings on the Settings tab.
And then it hangs. Can't get to Windows to do any adjusting. The same happens on all monitors that I've tried.
I don't get any display at all apart from what I put in earlier : no evidence of boot up although I can hear the computer making all the right noises. When I press F5, I don't even get the display message that I got earlier.
Not sure how I would know which is the graphics card, let alone if it's seated properly. As it's an old computer, it may just have been jostled while transported. I'll let it "settle", open it up and have a quick look and try again tomorrow perhaps.
