Hi I recently performed a system re-build on my Dell Dimension 3000. It was my first time and to be honest I'm not too great with computers! I obviously re-installed windows XP, the necessary drivers, GPU driver etc. Got to the stage where everything was looking good and the PC was faster but then trying to run counter-strike source and BBC iplayer was a complete fail. CSS now barely functions, it's very laggy and glitchy and the graphics are horrendous. BBC iplayer is v intermittent, i.e. plays well for a couple of seconds, stops and then continues for a couple of seconds and so on. I have downloaded the recommended driver for my GPU (Radeon 9250), which was the same one I was using prior to the re-build and all the CSS settings are low etc. Not too sure what to do now! I guess it's worth mentioning that I could not find my old XP installation cd so used another family member's XP Pro edition which installed fine. Is it possible that my GPU itself or the driver might not be compatible with XP Pro. Just a guess, I'm pretty lost with it all! Please please help, many thanks!
