Question about Dell Dimension 4600 PC Desktop
Video display started blinking, then went completely blank. Now, no image despite multiple reboots. Monitor works fine when connected to different computer using same cable. Replaced video card with new one but still no image on monitor. CPU seems to power up OK but cannot get any signal to the monitor. Diagnostic lights on back panel suggest possible video card failure (A and C yellow, B and D green) but new card does not make any difference.
If the video card is built into the motherboard then try starting in safe mode and reinstalling the drivers from scratch. Download the latest drivers from the dell website. Safe mode will reduce the resolution and use a generic VGA driver. If your video card is plugged into a PCI slot try unplugging the video card and using a different slot and going through the same process. If you are still not getting any output to your monitor and you are positive the monitor is fine then you may need a new video card. To be sure, if the video card isn't embedded to the mother board, you could take it out and try it in a different computer. Hope that helps.
