I recently installed a Leadtek GeForce4 Ti4400 into my system. I was previously using a GeForce2. With the GF2, I never had any problems playing games.. the only thing about that was it wasn't powerful enough to handle some of the newer games. I always used the latest official Detonator drivers. Now, I'm getting frequent lockups/bsod's while playing games.. Mainly I play Warcraft III so I don't know if this happens with other games. It would randomly freeze, and I have to hard reboot my computer. It doesn't happen quite that often if I don't ALT+TAB out, but on my GF2, I could ALT+TAB and have many programs running in the background. I'm thinking it may be an issue with running multiple background programs. Also, I occasionally run into a BSOD when exiting the game. I'm getting really annoyed by these minor things, but I'd rather stick my GF2 back in if this keeps up. I wanted to know if the Det4 drivers are more stable than the 30.xx ones. Anyone else run into this problem and has solved it?
