then boom it crashes. I have the lastest drivers and all that. Please help!

try clearing your cache, looks like it became corrupted. (secondlife.exe -purge)

If clearing the cache doesnt work then try uninstalling SL and clearing out the entries of SL in your registry, then reinstall. Its what fixed mine.
