Question about Dell Dimension 4550 PC Desktop
Sounds like a video card or slot issue. try to turn off the computer, disconnect the power cord, then remove the video card. try to blow dust from the video card slot using compressed air or use a vaccum. after that, press the power button for about 10 seconds to discharge any power left on the system board. reconnect the video card, reconnect the power cord and test. if same issue, try resetting BIOS defaults, try to update the chipset and BIOS. If both fails, try testing the video card on another system. if it is a PCI type of card, try testing it on another PCI slot on your system if available. if the card has same issue on another system, time to get a new one or use the onboard video card temporarily. Also, observe if video only disappears when Windows is already trying to load. if that is the case, either a video driver reinstall or operating system reinstall may also be needed.
