I already do some chkdsk /f and sfc, and even a clean windows installation. Drivers are up to date. The last two bsod appear when I try to use manycam software in chrome with driver verifier active. The last three happen with my Amd 7950 disconnected.

Sorry for my bad english, I do what I can Image

Hope someone can help me.

SINCE I POST I HAVE A NEW ONE
