Maybe you should try:
- Installing Service Pack 1 (didn't hurt my comp ... it even made the boot process that tiny bit faster ... and my l33t USB 2.0 hardware is working now ... )
- Restoring your system. (To a date when Hammer was still working.)
- Re-installing Hammer.
- Sometimes, even defragmentation or scandisk saves the day ...
When you try to run hammer, does it show the camera window ? (Try to load a map into hammer before it crashes, maybe by using windows explorer, selecting the hammer file and choosing "open with" ...) If not, your graph drivers may be causing your hammer-problem.
I think Half-Life Model Viewer uses the same rendering technique as the camera window in Hammer ... download that tool and try to view some models ... if that doesn't work either ...
