Software :: Snow Leopard Restarted While Running Photoshop?

I'm new to this forum, mostly because I've had such ease of use with macs over the years that I've had to search support forums. But with Snow Leopard less than 24 hours old, I've had my system "crash" 3 seperate times.

While running Photoshop CS2, the system will lock up. After a few seconds the system moves to a solid blue screen and then restarts the OS. It's almost like all programs running, including Finder are forced quit. There is "bong" over the system starting up or anything.

To clarify, I'm running a brand Mac Mini, 2GHz Intel Core 2 Duo. At the time of the crash I had nothing more than iTunes and PS CS2 running. During each crash I was doing simple tasks, a color selection, opening an effects panel and opening a very small smart object.

Also to note, I downloaded Safari 4 months ago when it was still in beta, and had no problems. The Safari that comes packaged with Snow Leopard is extremly sluggish and has forced me to use FireFox.
