Windows 7 Home Premium. After installing HP printer, on restart mouse and keyboard are not recognized. Mouse and Keyboard work great in BIOS and up to the point where Windows starts. Then unresponsive. Tried every option I know and found on google. Ran Windows restore disk, everything checks out fine. Doesn't matter if it's a normal startup or safe mode. Windows will not see either M or KB. Called Dell...they say the only option is a clean reinstall. i find it hard to believe for a Mouse and KB not working. Boots fine in to Windows...normal or safe mode, but no M or KB.
Trying very hard not to flatten their computer. Any thoughts?
