UO Second Age

earlier today on top of the bugs i reported i had something where i saw hundreds of th uo screen minimized. i couldn't open task manager, minimize it or anything. i had to shut my pc down. my uoclient.exe also gets fatal errors and shuts me out closing its self. what would cause this? im guessing uo crashing is my pc but could the graphics error be something else? should i just reinstall ultima?

I've experienced some sort of hang and stick on my screen every time i play it.

specially when I'm on the battle and many character are in.

I'm wondering because some games on my computer never stick or hang.

What is the problem on that?
