Hi Faiziq,
Let's try a few things to see if there is an issue with your operating system.
First go to Start > type in CMD and right-click command prompt and choose run as administrator.
Type in: sfc /scannow
After that is done, also enter the following:
DISM /Online /Cleanup-Image /RestoreHealth
If the above comes up clean, let's maybe do a check with Malwarebytes...go to Malwarebytes.com and download / install Malwarebytes and do a scan.
After all this do a restart and let me know.
