Windows 7: BSOD iaStorA.sys driver, DRIVER_IRQL_NOT_LESS_OR_EQUAL

11 Jan 2015   #1

Windows 7 Professional 64 bit


I've been getting intermittent BSODs for the last month. No particular pattern. Just sometimes locks up, can't start task manager, can't switch between screens, mouse doesn't work kind of thing. Shutting the laptop cover often eventually lets it shut down. Not always.

I've retrieved the last minidump which is attached. I think I need to reinstall iastor.sys driver but not sure, and not sure how.

Happy for any help you can give. Meemac

BSOD Occurs Randomly iaStorA.sys
Based on the BSOD I know that the iaStorA.sys file is the culprit and I've updated to the latest Intel Rapid Storage drivers. Unfortunately that hasn't helped. I also cant even do disk checks or a system restore becuz the BSOD always interrupts them. The BSOD also seems to occur randomly. Sometimes...
