If this is the first time you've seen this error screen, restart your
computer. IF this screen appears again,
follow these steps:

Check to make sure any new hardware or software is properly installed
If this is a new installation, ank your hardware or software manufacturer
for any windows updates you might need.
If problems continue, disable or remove any newly installed hardware or
software.

safe mode to remove or disable
components, restart your computer, press f8 to select advanced startup
option, and then select safe mode
