ZunTzu

Never had a problem before, but I haven't used ZT for a couple of months and today it is crashing my video card. The first time I got snow after a module had been open for a few minutes and had to reboot to fix it. The second time (different module) I got snow right away and then a system freeze.

I don't even trust it enough to launch it now.

Windows XP SP2.

Tried changing the ZT video settings, but it didn't help - still got snow and then a system freeze.

You're the first one to report this problem.
The symptoms make me think your video card may be overheating.
If it comes with a fan, can you check that the fan is still rotating?

I can't really see the fan on the card, but the only times it has ever done this is with ZT running - and I work from home so the computer is on all the time. And I have an Antec 900 case, which has four other fans.

I found that there was a recent update to my video card drivers (GeForce 8600GT). That seems to have fixed the problem.
