I am using Poser 4 with the latest patch and Windows XP Home. Everything had worked fine (except for a problem with the dials) until my hard drive crashed a few weeks ago. I've got a new HD and have reinstalled everything. Poser works fine, I don't even have the problems with the dials not working anymore. But whenever I close Poser, the computer restarts! This means that I have to go in and delete all the .rsr geometries of any figures that I was using or I get the dreaded "Cannot open obj file" message. I have installed the XP service packs. What is causing computer to crash? I am running AMD Athlon 1.05 ghz with 384 mb RAM with Geforce 2 Video card. Any suggestions?
