I've recently built a new system and I have been having problems with a few programs that I run. The programs list so far:
Nero Vision 4: crashes on startup
SageTV 6: crashes on startup /w higher than medium video settings (3D acceleration enabled)
Skype: crashes when other user tries to share their screen over video.
All BIOS, drivers and directX software are the latest versions. I have also tried rolling back to earlier versions without any resolve to the problem.
I've narrowed the problem down to having direct3D acceleration enabled in the dxdiag tool. Disabling hardware acceleration lets these programs function normally.
I've further narrowed down the problem to when I disable all of the cores of the processor except 1, the programs run fine with direct3D accleration turned on.
I've then tried testing the situation more by enabling more cores in different combinations. I've found that the programs are able to run with direct3D acceleration on with any combination of 4 cores enabled.
Whenever a 5th or 6th core are enabled however, the programs crash as before when direct3D acceleration is turned on. Therefore I believe none of the cores are faulty, but it is probably the software not being able to handle any cores beyond 4.
I found THG Task Assignment Manager which lets me make profiles for programs to have their affinity set to certain cores when they open. I have tried setting these programs to run on only 4 cores, but this has not worked either. I have to turn the cores off in the BIOS.
Some programs run ok with all 6 cores, while some crash unless I turn off 2 cores. Does anyone have any ideas or input? Would upgrading to windows 7 perhaps fix this issue, or are these programs just too old to function with 6 cores on any OS? I would like to be able to use all 6 cores, but I use these programs often enough that at the moment I am settling with only using 4.
Here is my build for reference:
