PC Troubleshooting for .dll errors

Last Updated: April 26, 2024

Question: I am noticing a number of .dll errors when trying to launch or play a game.  What can I do to troubleshoot and resolve these issues?

Answer: There are a number of dynamic link library files (.dll) that, if corrupted, can cause games to crash.

If you are experience a number of system or game crashes we recommend that you do the following:

Run a Full Virus Scan

Run a full virus scan on your computer.  While file corruption can be caused by a variety of factors, most completely unrelated to malware, but it is always a good idea to run a scan if you see these types of errors.

Once the virus scan is complete, run the Windows System File Checker (sfc) to scan for corrupted system files and restore them.

Backup (as needed)

If you have modified your system files, running the System File Checker will revert the system files such as Explorer.exe back to the default state.

Make the appropriate backups of your system files if you wish to save any modified system files prior to running the System File Checker.

Run the System File Checker
