im using AVG free edition... as I'm a limited bandwidth user... I'm not installing win updates
Perhaps you don't like using links in forums and that's why I haven't seen anything regarding my suggestion. So, see if anything in the following list provides a solution;
I would suggest you follow these methods and check.
Method 1:
Update Graphics drivers.
Follow these steps to update graphics drivers.
a. Press
Windows key + X and select
Device Manager.
b. Search for
Display Adapters and expand it.
c. Right click on the
Display Adapter and select
Update driver software.
Method 2:
Run sfc/scan.
The sfc /scannow command scans all protected system files and replaces incorrect versions with correct Microsoft versions. When the scan is complete, the System File Checker tool indicates whether integrity violations were found. If integrity violations are found, the System File Checker tool lets you fix the integrity violations.
Follow these steps to run sfc/scan.
a. Press the
Windows + X keys and click/tap on
Command Prompt (Admin).
b. In the elevated command prompt, type
sfc /scannow and press
Enter.
NOTE: This may take a while to finish running.
Method 3:
I would suggest you to run anti-virus scan on the computer and check.
I would also suggest you to scan your computer with Microsoft Safety Scanner, which would help us to get rid of viruses, spyware, and other malicious software.
The Microsoft Safety Scanner is a free downloadable security tool that provides on-demand scanning and helps remove viruses, spyware, and other malicious software. It works with your existing antivirus software.

Note: The Microsoft Safety Scanner expires 10 days after being downloaded. To rerun a scan with the latest anti-malware definitions, download and run the Microsoft Safety Scanner again.
Important: While scanning the hard drive if any bad sectors are found, the scanner tries to repair that sector, any data available on that might be lost
Method 4:
Step 1:
I would suggest you to boot your computer in safe mode and check. Here is the link which says how to do it.
Windows Startup Settings (including safe mode)

Step 2:
If the system works fine in safe mode, then I would suggest you to perform clean boot to check for the application that is causing the problem.
Clean boot: To help troubleshoot error messages and other issues, you can start Windows by using a minimal set of drivers and startup programs. This kind of startup is known as a "clean boot." A clean boot helps eliminate software conflicts
. Here is the link for your reference to perform clean boot.

Note: Please go through step 3 of the Kb to keep the computer in normal startup after fixing the issue
