Hi Devyanshu,
Is the computer under the warranty? if so call the acer in below link.

Also try to do the below steps to fix the issue by yourself. 

>>>Power Reset
Disconnect the charger. Please check for a battery reset PIN hole at the bottom of the device. The reset hole would have a battery symbol next to it. Insert a paperclip into the hole and press for four seconds. Let the computer sit for 5 minutes with no power. Reconnect and monitorthe CPU usage.

>>>End Task of running programs and Disable Startup program in task manager. This fix can help you quickly end high CPU usage issue when your device becomes extremely slow or even get stuck with running programs:

Press Ctrl + Alt + Del keys at the same time to bring up Task Manager; 
Select Task Manager > Check and select programs that are taking high memory and CPU usage > Click End Task to close selected programs or apps. 
Click on Startup on Task Manager > Select and right-click on unnecessary programs or apps > Select Disable to stop them running from Startup.

>>>Run DISM command to decrease high CPU usage

Right-click on Start and select Command Prompt (Admin), sign in with your administrator account;

Type: DISM.exe /Online /Cleanup-image /Restorehealth and hit Enter;

Type: DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:C:RepairSourceWindows /LimitAccess and hit Enter;

Type: sfc /scannow and hit Enter.

>>>Disable Superfetch and Windows services to fix Windows high CPU usage 

Press Ctrl + Shift + Esc to open Task Manager;

Go to Services tab and click Open services;

Navigate and locate Superfetch, right click on it and select Properties;

Click Stop to end the Superfetch service and click OK to confirm the change.

>>>Press Win + R to open Run dialog > Type: msconfig and click OK;

Check Hide all Microsoft services under Services tab > Uncheck all other remaining services > OK to save all changes;

Restart Windows > Enable any services individually and reboot PC > Repeat the process till Windows high CPU usage issue gets fixed by then.

On a regular basis, disk cleanup & disk defragment must be done to get rid of old, unused files & to reorganize files so that they can be read more rapidly.  If you've never done either, this is the reason for the screen to freeze & for the boot-up to crawl.  If you have installed more than 1 anti-virus program, that will also slow your laptop down; so delete the excess anti-virus applications.
