Just completed reinstallation of XP due to seemingly unfixable error with an ATI Radeon 9500 which turned the screen all fuzzy whenever I played a half-demanding game. Upgraded to a Radeon 9800 in the process ('cos it seemed like a good idea at the time, init?). PC works fantastic unless I install either Service Pack 2 or the latest VIA 4-in-1 and then it bombs before hitting the login screen, and the screen's all fuzzy again in safe mode. Frankly I can live without the latest 4-in-1 but will I survive without SP2? I scoured the forums for advice before doing the reinstallation and found what seemed to be a repair, involving Catalyst Uninstall, Via 4-in-1 install, .net framework install, Catalyst install and DX 9C install. It was running this supposed fix that led to the windows reinstallation 'cos it totally fried my PC. Any of you esteemed tech-heads out there thinking "been there, done that" I would so appreciate you giving me some pointers. Cheers.
