Did you download the upgrade? Forget about it. It's not stable yet. Delete everything and revert to a previous version:

or use a TPV:

Might be a heat problem, but without further info (viewer, OS etc.) it's just a guess.

If you are using the most recent update of LL's V2 viewer, try removing it completely from your computer anbd them replacing it with either an older version of V2 (available at http://wiki.secondlife.com/wiki/Category:Release_Notes) or a third party viewer (available at http://wiki.secondlife.com/wiki/Third_Party_Viewer_Directory).  If you install an older V2 version, disable the Automatic Uploads feature in Preferences >> Setup.

Per Tristizia's post, if your fans are not working correctly, or producing sufficiant cooling to function, your PC will crash as it over heats

Yes, there are griefer scripts that can make you crash.  A texture crasher essentially feeds your viewer enough textures that it overloads your graphics card by trying to display them all. If you are in a region that is griefed by such a script, you can simply TP out (or sometimes turn off all particles with CTRL + Shift + Alt + = , which can work if the script is overloading you with particle textures).    If you suspect that you have such a script, the smart thing to do is delete it.
