I have a slight problem with my video card, I have a Gecube 4870 ATI Raedon Card 512MB, this card works fine under Windows XP Pro 32bit, but recently I got Windows 7 Ultimate and ran 64 bit mode, I'm a gamer so most of my games now don't work, not even under Win XP mode, but the ones that do work, W.o.W. and MW2, keep suffering from Video Card Driver Crashes, so I downgraded to Win 7 32 bit mode, but the same crashes keep occurring, Win 7 says the Raedon Driver has suffered a critical error, but has recovered, but the game itself crashes. Is my video card out of date? Even doing a driver update dosn't help, in either 32 or 64 bit versions of Windows 7, I'm pretty sure the video card heats up. Normally when the card gets hot in Windows XP the fan thermal kicks in and cools it down, it no longer does this, but I can hear the fan continuously spinning but not at the force it used to. Do I need a Windows 7 compliant Video Card? Any help would be appreciated.
