How To Fix The IRQL_Not_Less_Or_Equal Error

Reader Question:
“Hi Wally, My computer started crashing with the error ” IRQL_NOT_LESS_OR_EQUAL “. I dunno what it means. I tried scanning the computer with an anti-virus but it didn’t help either. This is really annoying, please help me. Any help is appreciated.” - Ryan B., Canada

Before addressing any computer issue, I always recommend scanning and repairing any underlying problems affecting your PC health and performance:

Step 1 : Download PC Repair & Optimizer Tool (WinThruster for Win 10, 8, 7, Vista, XP and 2000 – Microsoft Gold Certified).
Step 2 : Click “Start Scan” to find Windows registry issues that could be causing PC problems.
Step 3 : Click “Repair All” to fix all issues.

Setting up weekly (or daily) automatic scans will help prevent system problems and keep your PC running fast and trouble-free.
