How can i try to fix my Graphic Card?

[jlp123]

Hello. 1st i should say that my Graphic Card is a GTX 460.

So, long story short, i was playing CS:GO normally when suddenly the colors started to get weird and that was followed by a blue screen.
I tried several things to fix it but nothing worked sadly. In the end, everytime i turned my PC on i had a black screen with the monitor's led blinking after the Windows logo. Sometimes i was able to login, but everytime i opened the NVIDIA Control Panel i ended up with the black screen again. (btw my Graphic Card "GTX 460" showed up on the "Device Manager").

Then i installed an old graphic card i had here (a 7300 =/) and my PC started working fine.

But now, before i go buy a new Graphic Card and throw this one in the garbage, is there a way i can try to fix it? Maybe opening it up and cleaning it? I tried the eraser thing but it didnt work. Any videos that could help would be appreciated.

Thanks for the attention!

since it is basically worthless now, (like $30 if you are lucky), I wouldnt bother with it. I would just pick up a gtx 750 ti on ebay for about $70 used, which will be a good upgrade, and you wont have to upgrade your psu. Hope this helps!
