I have a laptop Inspiron 5520. The graphic card is not working properly and games do not run efficiently. I called tech support of GizmoSupport and they told me that it is a problem with my RAM. But my RAM works fine. I don't know what to do. Please help with the same.
Restart the system and press f12 key on startup - choose diagnostics. Let it run the diags and if you encounter any errors - make a note of the complete error and report the same to us. These are onboard diagnostics and they might possible pick some error if the hardware is not functional.
If there is no warranty, then you could contact our team to get a quote for a paid service call - http://dell.to/1vnT6CQ
