About once every hour my Dell Precision M6300 stops and has the infamous blue background with white text, then restarting.

At some point from the display/graphics driver the advice came to download the new driver. Did that. Now the lap top only stops about once a day and tells me something about a parity error in the memory, And now the driver stops once an hour and restarts. Well that takes less time but is a nuissance. Windows 7 SolidWorks 13.

Do I need a new laptop or what is my problem?
