i work for a computer wholesaler in ca as a tech , and 90% of the time i got this
error "IRQL_NOT_LESS_OR_EQUAL" i ve tracked it to be memory related , either people
messing with the computer mixing ecc memory with non ecc ,or incompatible memory
modules,corrupted memory,
if your computer does this since you builded it or since u got it, chances are that
u got incompatible memory or a mix of memory modules (that most of the time u cannot
check visually becouse they dont have a sticker lol , and u need to use an utility
to check it usually "memtest" .try it ,normally a good brand memory module is less
prone to be incompatible,
like samsung and kingston for example ,
