MSI GAMING APP

Hello,

overclocking can sometimes cause issues (hardware not supporting modifications, overclocking too "strong"...).

Before proceeding with this type of maneuver, always gather information about your hardware and what it can handle.

In this case, the most reasonable thing to do, in my opinion, would be to reset the settings to default in the BIOS, and then restart.

You will return to the basic settings, which should not interfere with the PC's startup.

The manipulation inside the BIOS varies from one manufacturer to another. Try to gather information on the MSI website.

Sincerely.

My problem is solved, I don't know if this will help others but to put it simply, I just unplugged the cable that connects the motherboard to the power supply. From that point on, my PC turned on normally (meaning it didn't shut down every 3 seconds) and after that, I pressed the "delete" key several times, which finally brought up the BIOS. I should mention that both my keyboard and mouse turned on after this disconnection. Does this have a relation? Did the motherboard not manage to handle all the information from the start? I have no idea. But in any case, my problem is solved; I'm posting this from my PC and everything is working very well. I thank the people who took the time to respond to me and for trying to solve my problem. Thank you and best wishes.
