I got a HP comp about two years old, it's been working ok but one day I turn it on there is no video. The system boot up w/ 4 beeps.
It's not the monitor because I test it w/ another known good working monitor. I found the video is on board. I installed a PCI Video card hoping that it will overide the onboard video. But it does not work. Still no video.
Please help. Appreciate.
