Helios 300 (PH315-52) issues after bios update

I've had a Predator Helios 300 (PH315-52) for a little over 2 months now, and while trying to troubleshoot blue screen issues I updated the bios to version 1.06 from the version it shipped with. Version 1.06 was the most recent bios version at the time of the update and I downloaded it from the Acer support website. The only thing plugged into the laptop during the update was the power cord. The message on the screen said that the bios update was successful and when it rebooted it went right to the Windows desktop with no problems. I played some games on it for an hour or two and then shut it down for the night. I noticed it took a little longer than usual on the shutting down screen, but it didn't blue screen and did shut off by itself so I didn't think much of it. When I went to start it up the next morning, the keyboard backlight and fans came on but the screen remained completely blank with no backlight. I tried turning it off and on a few times, and tried the projector mode and display backlight keyboard shortcuts without success. I then took it to a local computer repair shop where I was told that it needed a new motherboard and that I should send it in to Acer for the repair.

Hoping to avoid having to ship the laptop out for repairs, I took it to another local computer repair shop for a second opinion. At the second repair shop, they were able to get it to boot after turning it off and on a few times and it went right to the Windows desktop again. This shop said it might be a hibernation problem. I had already disabled the fast startup option in the settings and after the laptop was back up I disabled hibernation using command prompt. Unfortunately the issue has persisted, meaning the laptop will eventually boot, but I'm having to turn it on and off several times (often 10 tries or more) before it will do so. It doesn't seem to matter if the power cord or any USB devices are plugged in or not. This issue doesn't affect restarting. When it does eventually boot, the keyboard backlight setting is back to shutting off after 30 seconds (I set it to always on) and cool boost is turned off (I set it to on).

I've been dealing with it for a couple weeks now, hoping I can either find a way to fix this or it will resolve on it's own, but I'm worried that booting it this way will eventually damage it. I've been researching a lot online and haven't been able to find anyone else having the same problem. So I was wondering if I should attempt to update the bios to version 1.08 or if it's time to just give up and send it in for repair? Or could this possibly be caused by a different issue?
