I've been having a problem with my computer lately. Can you tell me how to fix it?

First, check that all your cables are properly connected and secure. If they are, then try restarting the system. If this does not work, you may need to run a diagnostic test on the system. This can be done by running the diagnostics from the BIOS menu or using an external device such as a USB drive. You can also contact technical support for assistance in troubleshooting the issue.
