Hello--

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
