black screen after 5-10 mins of gameplay (fix)

I have discovered what the problem is for this. (no guarantees)

My screen did go black after around 5-10 mins of game play, but now it doesn't.

The problem to this was the graphics card. I swapped my graphics card around with an
older one that I have, and now I can play fine.

If your card is still under warranty, then you can send it back if you think there is a problem, and get a
new one. only send it back to the manufacture if your sure it is faulty.Try testing with an older card you have,
or any other card you have.

Before you do that try updating your drivers, depending on your graphics card.

Here is a link to the NVIDA website where you can get the latest drivers:

Here is the AMD website:

If you have no idea what graphics card you have you can use this program:

Hope this helps.
