You can troubleshoot further manually by performing a Clean Boot. A Clean Boot starts a system with minimal drivers and startup programs. When you start the computer in clean boot, the computer starts by using a pre-selected minimal set of drivers and startup programs, and because the computer starts with a minimal set of drivers, some programs may not work as you expected.
Clean-boot troubleshooting is designed to isolate a performance problem. To perform clean-boot troubleshooting, you must disable or enable one process at a time, and then restart the computer after each action. If the problem goes away, you know that it was the last process that was creating the problem.
