I recently got an HP Pavilion 533w pc. When I plugged it up to my monitor and keyboard and turned it on this is what happened: the system sounds like it is booting up, it lights up the keyboard in the regular test PATTERN, the lights on the pc show that it first checks the cd drive then the floppy drive, but the monitor still shows a “Self Test” box that reads: “This monitor is working. Please check the video CABLE and computer.” Both the keyboard and the monitor work fine on ANOTHER pc that I have. And, of course, I did check to MAKE sure everything is plugged in tight and correctly. It doesn’t appear to have a separate video card, it looks like the monitor plugs directly into the motherboard. The only other separate card in there is a modem. Based on this information, can anyone give me an idea of what to check or replace next?Did you recieve a driver CD with the machine ? ?
If so you could try re-installing the motherboard drivers...I didn't get any SOFTWARE with this computer. However, I do have a bootable copy of Windows XP Pro with a key. I tried to boot up to it in the cd drive and nothing changed.
