Hi TechACE,
It would be annoying when the computer crashes after installing Windows with Service Pack 2. I suggest you to install all the drivers starting with the Chipset before rebooting or installing updates. You can download the drivers from the following link:

Please enter the Service Tag in the “Yes” section and click “Submit”. Download and install the drivers and let me know if you need further assistance.
