wingman - any reason you skipped the suggestions in the thread and just blew out windows?
The reason I tried another clean install was because of all the problems. When I select delete on advanced install the only other options is new or next. so I clicked Next to let the installer auto-create/format only the necessary partitions and begin install.
After the third clean install the sound in games does not cut out, also BF4 is not freezing. I do have the same problem with Chrome crashing to desktop without error, when I reopen Chrome it says chrome closed unexpectedly would you like to restore last session, that is why I think it is windows 10. I tried uninstalling chrome and reinstalling no joy. Chrome works fine on my other PC, also I didn't find any known recent problems with chrome when I checked.
I'm testing another browser however it takes a long time for failure with Chorme so it could take a while.
My chipset driver is installed also windows 10 is updated. All the last installs I did are one program at a time, that seem to help, no multitasking installs.
