here's the info ( sorry)
A problem has been detected and windows has been shut down to prevent damage to your computer.

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

If this is a new installation , ask your hardware or software manufacture 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 & press f 8 to select advanced startup options and than select safe mode
