Many Times You will find that the user has mis-configured the way that the video card is delivering a signal to the monitor. When that happens, the display may be distorted, unreadable or the system may just go dark on you. This segment of the course will explore how to deal with problems related to video card failures and mis-configurations.
Video Hardware Failures
Occasionally the video card it self will fail. You will know this is the case if you hear an audio error code from the PC indicating a video adapter failure. Such an audio error code will should like 1 long and 2 short beeps, 1long and 3 short beeps or 1 long and 8 short beeps. When this occurs, you may want to try the following things before replacing the video card:
- Re-mount the video card in the bus connection and see if this corrects the problem. Occasionally board creep will cause the card to malfunction and re-mounting usually solves the problem. You may also want to try inserting the board into another socket to see if that resolves the problem.
- If the video RAM is socked on the video card, make sure that the RAM is inserted correctly into the sockets or connectors on the board. If you suspect that the socketed RAM is defective, remove the RAM, re-install the board and see if the problem resolves itself. If the RAM is defective, contact your vendor or manufacturer for replacement RAM.
- If the Video card is HOT, that may be an indication that a component on the board is defective. If this is the case, replace the board immediately. If the video card does prove to be defective, replace the card with another of similar type. If possible, try to install an exact replacement card. so that you will not need to reconfigure any video drivers in Window 95/98. If you do install a different brand or mode of card, be sure to install the vendor-supplied video drivers, so that the user will get the maximum performance level from the video card.
