Acer Predator Triton 500 i7-9750H Laptop Chrashes to Show "No Bootable Device"

This is going to be a strange on for you guys. I have a month old Acer Predator Triton 500 i7-9750H 16GB Ram RTX2060. I was having problems with the laptop overheating to 90C+ and shutting down so I used Intel XTU to under volt the cpu to -0.120 (From factory it is -0.100), turn off turbo boost short power and lower turbo boost max to 41W. That solved the overheating problem and is now generally between 79-83C with heavy gaming. Now about once every 3 hours it will completely crash and boot back up to a No Bootable Device message. The laptop can be turned off and back on many times to show the same message but when I unplug the display cable going to my monitor the next boot will work fine. Monitor is a Acer XFA240 cable is display cable on monitor end and mini display cable on laptop end. I am completely puzzled by this please help

Thank You

Does it show a BSOD when it crashes? What is the message/error code it shows.

When crashing it normally just goes straight to a black screen and then immediately starts to boot like it's a random restart. But the first predator logo pops up and the spiraling loading dots under it don't show then it goes to a picture of a drive in the middle of the screen and only says "No Bootable Device". Once unplugging that cable on the next reboot I know its booting when I see the loading spiral under the Predator logo. Once or twice it has crashed to the blue BSOD screen but I regrettably unplugged the cable and shut it down ASAP bc I was in the middle of a PUBG match when it happened (The percentage never got off %0). Hehe

I will take a picture if/when that happens again.

Black32Hawk Thats really a weird one could it be the cable the issue here ?? also i would try to use TS to undervolt instead of xtu download a ready ts conf for you cpu from the fb group announcements and see if the issues persists also if you had bsods get bluescreen viewer and see what caused them they are still stored in your system for you to open and check

having the exact same issue as described by OP, only happened once, couldn't even get into the boot menu, ctrl alt and del 4 times to get it to boot up. No BSOD or anything.
I got it back up from sleep/hibernate when screen didnt turn on but the keyboard did.
Next 3 ties the error for no bootable device came, again couldn't get into BIOS/UEFI or the boot menu,
4th time after ctrl alt del, it worked fine
i recently replaced the ssd but having done so 3 times before, i am pretty sure there was nothing i did wrong this time.
