If this is the first time you've seenthis stop error screen,
restart your computer. If thisscreen appears agai, follow
these steps:

Check to make sure any new hardware or software is properlt installed.
If this is a new installation, ask your hardware or software manufacturer
for any windows updates you might need.

If problems continue, disable or remove any newly installed hardware
or software . Disable BIOS memory options such as caching or shadowing.
If you need to use safe Mode to remove or disable components, restart
your computer. Press F8 to select advanced startup options, and then
select safe Mode.
