Hi, My name is Tykia my laptop Acer Windows computer just froze and is making a loud buzzing sound for the first time. I was on Facebook playing a game. Then out of no where it froze. I was wondering

Usually the problem might be existing with the hard disk or OS.
check your system for graphics quality . when u play a game for more time,the processor might get heated(in case of low graphics quality).when the OS files got fragmented ,it takes more time to load.reboot the system,when the system works slow,re install the operating system.

Do a hard reset. Press and hold down the power key till it turns off. Wait a few mins and then turn on again. Run your antivirus software if you can boot back up again
