Blank screen on monitor

TFT monitors do have a habit of giving up completely whereas CRT monitors will usually show signs of distress for some time before failing. The very first thing is to make sure that your monitor is receiving power and is switched on. Check the power cable, the fuse in the plug (if there is one), the connection to the monitor, whether the monitor is switched on and also that nobody has accidentally turned down the contrast/brightness control (if there is one). Next, try your monitor on another PC, then try another monitor on your PC. This should identify whether it is the monitor or the video card that is faulty. If it is the video card and the video is the standard on board video, you should not need to replace the motherboard. You can get a separate video card which plugs into one of the slots. Don't do this, however, until you have identified that the fault is definitely with the video card. If it is not the video card, then you may need a new monitor.

You Probably need to install a new PCI video card. Mine did the same thing and I put the card in it and it was fine. A few days later my sound went south and I had to go back and get a sound card. Art
