Workaround :

- > Try in Safe Mode ( Keep tapping F8, as soon you turn on the computer to get Advance Boot Options)
- > Try disabling Startup items and non MS Service (How to disable startup items)
-> Disable Hardware devices if the above step didnt work (How to disable hardware devices)
-> If the problem resolved after disabling the hardware devices you can check enabling one by one to see which hardware cause the problem
