Do you want to fix driver error IRQL_LESS_OR_NOT_EQUAL in Windows 10? When Windows 10 runs properly, then it runs quite well. When it doesn’t run properly, you can then view the terrific blue screen of death (BSOD). The BSOD or blue screen of death can’t offer much help in fixing the bugs that caused it. However, by default Windows will restart your PC seconds after displaying you the BSOD. You are lucky if you can catch the actual error that caused it.
