Run Dell Diagnostics F12 at boot up. Run all tests.

No errors found in diagnostic test. Someone must know what this means!

Just to be clear, no one answering questions on this forum works for Dell. We are all users just sharing the knowledge that we have.

If anyone else on the forum has had the same problem you can find it by using the search tool at the bottom of the page. Try using as few works as possible such as COMPUTER BEEPS as a start.
