Book 13 Perplexing BSODs

Hey all I have a friend with a Razer Book 13 (RZ09-0357xxxx) with unbelievable crashes. It started with severe GPU artifacting and display issues, and was sent back to Razer. They appeared to address the GPU issues (which were probably heat related). The device still gets crazy hot (100*C under mild load) but interestingly, that isn't what causes the crashes. On a brand new fresh Windows install, with all firmware updated, with zero new drivers added, this thing is crashing completely randomly. The only commonality is the keyboard is being used. But the style of failure ranges from KMODE, kernel panic, and other completely rare and unusual failure points. Eventvwr tells a different story every single time but there does seem to be generic IRQ errors throughout. WTF is going on here? ICM bridge overheat? Something else? It's completely random and not attached to any clear cause or temperature. I do get the odd crash following artifacting. My hunch is it's something between the GPU and the keyboard drivers, but nothing obvious shows up in any diagnostic.
