Strange thing I noticed, picture this. Format all drives. installed a fresh slipstreamed XP-sp1 PRO version. All hardware correctly installed (incl. my Leadtek Winfast TI500). Well lets install the 41.09 det drivers. Oops warning, previous det version already present on system. How is this possible? Does WinXP contains det drivers voor Nvidia based cards? Second I run into, was the fact that the DetDestroyer tool didn't recocnize the installed drivers! Now I installed the 41.09 drivers but I have the problem that 3D games are choking each 5 minutes. Is it true that XP conatins det drivers? Might they be the cause for some lock up probs?
