Hi guys

I have an Alienware X51 R2. The computer works well. Suddenly I began to notice that the monitor shows "entering to power-saving mode" without reason* I called DELL and they change me all components except the processor and graphics card. That made it work a couple of months until I got the same error. This time DELL changed the graphics card only by a GTX 670, it worked well again a couple of months.
Now the computer experiencing the same error and some more like: black screen, windows crashes when it shows the desktop.

What i have done:

Update Drivers - Use previous versions
Update Bios.
3 Different OS
Check the temp of the graphic card 1º - 3º below the max.

Any suggestion?
