Want to check if my graphics card died

A few days ago, I was playing Guild Wars 2 and all of a sudden, my laptop screen froze. I tried to Ctrl Alt Del, spam my keys and whatsoever but nothing happens. Waited for about 10mins and decided to force shut down it. I have played this game for more than 2 years but this is the first time I encountered this problem. When I switched on the computer, my nvidia graphics card showed error 43 in device manager and I realise that my laptop seem to run slower. Reinstalled drivers but nothing happened. So I decided to toy around with the graphics card. I plugged it out and replaced the thermal paste and plugged it back in and it worked. However, after playing Guild Wars 2 for another 1 hour or so, the same thing happened. I tried doing the same thing as before but to no avail. Since the computer ran slower as compared to usual, I decided that I might as well do a system restore. Everything went well but the moment I opened Guild Wars 2, even before i could log in, the computer froze. Tried the same thing but to no avail and so i decided to do another system restore but error 43 still persists and noticable drop in laptop performance. While I suspect that the nvidia graphics card may be dead, is there a possibility that some other parts are responsible for this issue and what are the they as my guts are telling me that a dead graphics card should probably not be cause performance issues (pardon me if this is wrong as I am a computer noob :)).

Specs are as follow:

Alienware m17x R3

Intel Core i7-2860QM CPU @ 2.50GHz

8.00 GB RAM

Windows 7 Home Premium SP1 64bit
