This problem can be caused by various types of things such as virus attack, maximum memory, old hardware drivers and more. There is a way to get rid of a ‘frozen’ screen, some of which are hitting or completely rebooting the system.

Last Job – You should hit the Num Lock button available on your keyboard to find out if the computer is actually frozen. Check out the Num Lock LED when you turn it on whether it is on or off. If you are able to turn on and off the Num Lock LED and get in Windows, at the same time hit CTRL + ALT + DEL buttons. You will see several options depending on the Windows version you are using. Remember, this is a near catastrophic error. Although we are resolving a problem outside of this problem, keep in mind that if you fail you can lose any unsaved data in your current session. If you are lucky, and the computer responds to the CTRL + ALT + DEL command, try loading the task manager. From there, try to find out which programs upgrade the CPP and try to finish that task.

Issue in software – It may be that locking up due to problems with computer software. If you find a computer stabilizer, when running a specific program, check if any updates are available for that particular software. Also check the updates available for your operating system.

Hardware problem – If the frozen computer is causing a hardware problem, then it can be so much – bad memory, dozens of excessive chips, hard drive errors, video card problems, etc. The hardware can be tested by swapping out the bad parts for better ones. You may need a computer service to do this.
