When you say crashing, do you mean freezing (locking up) or bluescreening?

 

Do you know what manufacturer the graphics card is from?

 

Does this only happen after you exit a game?

 

Sounds like an issue with windows (I'm assuming you're using Windows) or your graphics driver version. 

• Are you using an old or beta graphics driver?  If you don't know how to check do Win+R -> type 'dxdiag' (without quotes) and reply to this thread with a screenshot of the display tab.
• If you've overclocked any of the components in your system, undo that and observe if the crashing behaviour continues.
• Have you tried reinstalling Windows?  This is a last resort but if you have a recovery partition you may be able to restore your system to before this issue started occurring.  Be sure to back up all your files before you do.  Your computer sounds like it came from an SI so there could be some underlying issues with the OS (for an example of what I'm on about, watch the video Final Verdict - $1500 Gaming PC Secret Shopper pt4 and pay attention to anything pertaining to the Dell system).

That's all I can come up with at the moment but if I think of something else I'll add a follow up if your issue isn't already fixed.

take out one stick of ram and test with just one stick in both of the ram sockets .. I presume 2 x8gb ? ar run your system with the sides off so there is no heat build up ...try running unigine benchmark for 4 hours on max settings

and furmark later
