yes that's right XP. I run two PCs with XP, one is now a very old xp2000 running at 1.3 or 1.6 mhz overclocked. But its a great PC with a good sound card originally supplied with dedicated software for the card, a Creative Sound Blaster Live Drive.
Having recently reinstalled XP for the first time on this PC this December, the ensuing pandemonium of graphic driver chaos, crashes and lockups, I found this site Guru 3D. Not only do they have a library of older drivers, but also neat section of utilities where I found a direct x rollback app enabling me to reinstall some old software that will only run with direct x 8.0, strange but true
I have recently discovered that direct x 9c or later can effect XP in some odd ways. causing strange symptoms of excess drinking, swearing, hair loss, not mention bouts of depression and anger.
I would highly recommend that you never throw away old drivers of any kind. Happy days to you all.
