thanks for the help Thomas! 😀 I have managed to resolve the issue!
It seems it was the Microsoft Intellipoint mouse driver 6.10 that was causing all the mess.(who would of thought?)
replacing it with the old, 5.5 driver fixed the issue!

But thank you for your suggestions and Merry Christmas! 😀

Heres something interesting, I turned hardware acceleration in display settings off completely. This fixed the problem.
The only problem is, now I have no hardware acceleration at all, giving me close to no performance at all in pretty much anything. Obviously After Effects doesn’t run well like this.

But at least this makes it almost certain that the problem is related to the graphics card.

Thanks for the response!
I have tried both the newest driver, and the one that dates just before the newest one.
I have also tried with and without OpenGl support, hardware accelerated panels, multithreading, allowing more and less ram to the card and the cache. I’ve also tried deactivating the default windows XP look for the windows classic 2000/98 look. But nothing has had any sort of effect so far 🙁

The system came prebuilt, so I doubt (and hope not) the power supply would be a problem! Also, I can play heavy games and watch HD video in VLC without any problems at all, and the temperature is only about 55/131 degrees at full load.

but once again thanks for the reply!

I had the same problem as you, with my GeForce 7600GT! The problem was, that OpenGL didn’t work. And without the openGL acceleration, it can’t be played back in realtime, not even if it’s just plain video. I have to admit i don’t know what the AJA card is XD so i hope i haven’t misunderstood the issue

But the trick that did it for me was completely reinstall my graphics driver. The thing is, you have to uninstall your current driver, before installing the new one off nVidia’s website. I used a tool called DriverCleaner i think. Reinstalling it completely should fix the openGL driver, so after effects can find it, and thus enable openGL acceleration and everything will be much faster!

Try it even if you do have the newest driver, that’s what did it for me!
