I've had my HP Omen gaming PC for almost 2 years now and after playing the other day, it turned off on its own. Now whenever I turn it on the lights inside the case are on and the fans are working, but it won't boot up. All I see on the screen is blank. I unplugged the PC and tried troubleshooting and nothing is working. What may be causing this and how can I fix it? I've been trying for a week.
The first component that I always suspect when I hear these symptoms is the power supply unit (PSU). If it is failing or has failed it can cause many different symptoms, but the main one is the computer shutting down on its own. There are numerous guides online to help you test the PSU. Also, you can test the memory. If you have more than one module you can remove both of them and replace them one at a time and try to boot. Place the single module in the slot closest to the processor. Last, but not least, check all of the connections to assure they are tight. A loose connection can cause this problem.
