Hello. I've been dealing with this issue for some time, hoping I can find a solution. ---------------------- Issue: Starting up Poser 7, Daz3DStudio, and Blender causes my entire system to lock up. My only option is to perform a hard reboot and restart. I can not even open the program to change settings because by then my system is hanging. The farthest I have ever gone is the loading screen. lol Always freezes at the same point as well. In Poser 7, a few seconds after the loading screen appears (it freezes). In Daz3D and Blender, immediately after double-clicking the desktop icons (it freezes). While I can load and enter 3DS Max 2009, rendering a Reactor scene results in a freeze. Possible Suspects: -OpenGL related -I have 3 versions of Microsoft Visual C++ (including 2005 and 2008). One is a 32-bit program and I have a 64-bit machine. Possible conflict? -Bad Drivers Unsuspecting: --Faulty Hardware. I can play high-end games with no issue. My System Specifications: E8400 @ 3.0ghz Sony DVD-RW Western Digital 500gb HDD HIS Radeon HD3870x2 Patriot 4gb @ 800mhx 4-4-4-12 Gigabyte DS3L Rosewill 600w Raidmax Smilodon Windows Vista x64 Thanks in advance.
