yes everything is install properly, got all the new drivers etc etc.
The thing is, sometimes it automatically reboots but sometimes it freezes my computer and just before it makes a thin crackling noise on my speakers?

Possibly the OS installation is screwed. Your pc also might be searching for files which do not exsist, or have been moved. Make sure anything you've deleted in the past while is DELETED properly. And, if you can, try reinstalling the os

go to control panel then administrative tools then services. check if the service is disable or not. or else just reinstall a fresh copy.
