Crossfire BSOD

Dont format your hard drive. I to have the BOSD. My blue screen is: XDVA359.sys from what I can find on this its a. XTRAP error. The XDVA.sys files are in the regedit. Its files that XTRAP runs when you start. From what I have found is that it has something to do with Antivirus programs. I cut my Antivirus off. I can play but, the game play is very bad, My FPS are 125, but drop to 20 at times. Never had this problem before the patch. When I quit the game I get this BOSD. Any one working on this? Any help at all? If I fix mine I will let ya know.........

This worked for me, stopped the BSOD for now ? Changed the Virtual Memory size.
I had zero paging file size, changed to 4990 MB did the trick. Dont know what changed in the patch to cause problems. It was always set like this before the patch. worked fine then. Anyway hope this helps. Windows XP : Control Panel, System, Advance, Performance, Settings, Advance, Virtual Memory, Change..... Now you can let windows set the size by clicking, System manage size. I set my own size. You should set it to 1.5 the size of installed memory. I used 4990 mb for 4gb of memory worked fine. Hope this helps.
