Laptops General - Read Only

[Bluelv702]

My laptop has been acting up for almost a week. The issue I'm having is that my laptop will turn on, go to dell logo, then turns off then on, and does it all over again. I've ran the diagnostics test but no errors come out. Says all test passed. What can I do to fix it?

Please run diagnostic test again. After quick tests, click on Hard drive, and then Thorough Test Mode. Run Memory as well.
