While watching youtube I got a blue screen with the "IRQL_NOT_LESS_OR_EQUAL" error message. This is not the first blue screen to occur, but it is the first time with this error (I do not remember the other codes). The blue screens are not tied to any particular action, but seem to usually occur when I am either watching youtube or sitting on the desktop right after bootup (but to be fair that's about 90% of my usage). The blue screens began soon after I updated my motherboard to an MSI z97 Gaming 5 and updated my OS to windows 10 from 7 at the same time, so I am not sure which is the cause. These crashes happen once or twice a week and the computer works fine after its reboot. If any other information is needed please let me know. Thanks!
