I've got a Hercules 3D prophet III Titanium 200 card and I'm having real problems loading a driver that will work with windows xp professional. Tried the Detonator xp,drivers fron nvidia, drivers from Hercules, even had Hercules send me a step by step guide - still nothing. The driver loads ok but when I try to change the resolution from 600x400 to anything else the screen just goes black and the pc locks up. Any body got any ideas, besides get another card! The cards been tested, and it all works great with Windows ME.
