From past experience with owning a couple of these in the past, first of all try a reset by holding down the power button for 30 seconds and then waiting a couple of minutes before powering on again. Another thing to try if you've got an SSD installed is to remove the SSD from the laptop, and then power it on again without it installed. Older MSI laptops with these early type of SSD's can get into a boot loop where the BIOS hangs due to a glitch within the UEFI facility and needs resetting.
