Update / Disable BitDefender.

Perform a System File Check to fix corrupted system files Win 7, 8, 10, Vista: https://support.microsoft.com/en-us/kb/929833 Win XP: https://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/system_file_checker.mspx?mfr=true

See if there are updates for your graphics drivers https://support.mozilla.org/kb/upgrade-graphics-drivers-use-hardware-acceleration

Ran sfc /scannow and it found a few issues and fixed them. Ran Intel driver update which installed new graphics driver. Right now no problems.

 Thanks

Glad to help. Safe Surfing.
