i've gotten some unfortunate bluescreens with my current laptop, but they're super rare, to the point where i don't really remember what caused the crashes in the first place.
my last laptop though... wow. i think one time i couldn't get past the bootloader once because i messed something up with deleting the linux partition of my hard drive (because i wasn't going to use it, anymore). idr how i fixed that (i restored the partition somehow) but... yeah, it wasn't a fun time. u_u
