My brothers computer screen is not coming on. I have tried the screen on another computer and it works ok, so it is not a monitor problem. He has had a problem with the screen coming on before and has taken it in and had the RAM replaced and fixed it. It had 1 x 128mb and 1x 64mb SDRAM PC100 ram in it. I replaced this with 2 x 128mb sdram, but the same happens. The screen’s green light comes on when the computer is turned on, but nothing comes on the screen. The computer beeps, the beeps another 3 times. Does this mean it is a video/graphics problem? The computer is about 4 years old and has on board video/grpahics. Do this mean that if I tried installing a graphics/video card, there will be problems because of the onboard one – if the problem is the graphics?
Thanks
