Hello,
 
I've upgraded from a GTX 670 to a GTX 950(Evga) graphics card inside an Alienware x51 r2.
 
The card was running fine for a few days,and all of a sudden my computer shut down while playing a video game.
 
Now the PC will not start with the GTX 950 card inserted into the MOBO.However,it will start with the GTX 670.
 
SPECS :
 
i7 – 4770 CPU @ 3.40Ghz
16GB memory
GTX670 2GB
330W PSU
 A10 Bios
 
Any ideas or help?
 
Thanks in advance!
 

I would either exchange the card with the place of purchase (Newegg for example) or contact EVGA by phone.  EVGA will replace the card for a new one within 30 days of original purchase and should pay shipping (if you ask for a prepaid label).  After 30 days they will usually replace it with a re certified product.  If you RMA with the place of purchase or EVGA doesn't really matter (both should be fairly easy).
