Hi Dimmi1,
Are you able to boot the computer into SafeMode? I take it you saw the perfmon error when running the collection app from SafeMode? We will need the zipped SysnativeCollectionApp directory from your documents folder, and/or an upload of your MEMORY.DMP file from the BSoDs to be of much help. It will complete even if Perfmon doesn't run successfully, so you can just ignore that part.
