I have a custom laptop with an MGM45WU motherboard. A couple of weeks ago, the Intel 5100 WiFi adapter died. I replaced it with another 5100 adapter. After installing the adapter, I began having issues with booting up and shutting down the laptop. When I boot the laptop, I receive a "ME is Initializing" message after the BIOS flash and then it hangs. When I shut down the laptop, it does not completely shut down. Windows shuts down and the monitor goes black, but the computer is still running. This also happens when I close the laptop lid. It no longer goes to sleep mode. The only way to completely shut down the laptop is to unplug it and remove the battery. This issue occurs 50% of the time when I boot up or shut down. A few days ago, I reinstalled Windows hoping that would fix the issue, but it did not. Is there a fix? Any advice would be greatly appreciated.

In this case we suggest you to contact the seller or integrator of this system since the Intel Wireless Adapters are meant to be professionally installed by Original Equipment Manufacturer (OEM) technicians on certified systems only.
I checked some information about this motherboard and even though it seems to be a legacy product now, you may try updating the BIOS:
