I wonder if you put in one of those new 6Gb SATA drives and need to speed limit it. But that's a wild guess often than the new drive is DEAD.
Help, my PC with Windows 10 won't shut down properly
Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
