Just hit a restart after 24-days-and-something uptime of my Windows 7 x64 based laptop and at boot time saw "Installing device driver software" systray message, then got "You must restart your computer blablabla".
Nothing was saved in event logs but after checking one by one hardware components in "Device Manager" found that my second hard disk is with a different name, not the expected trademark and model:
Does anybody know what's causing that?
