IRQL_NOT_LESS_OR_EQUAL at the top and then it restarts instead of shutting down. If I disable the modem, the shutdown was fine.
I have downloaded a modem driver from Dell, and when I try to install it, it says it can't find the modem. System was recognizing it as an In-Build CX11256 by Conexant.
I physically removed and replaced modem which didn't help. I uninstalled modem device to see if I could reinstall it, and now it's trying to install it as a video controller which fails because it's using a modem driver.
I appreciate any help you can offer. Thanks in advance.
