My New Graphics Card Problems

[PCN00B123]

I was just wondering if anyone could help me with my graphics card. It having some problems with nothing else but minecraft. Now I've noticed there's defiantly Coil Whine on minecraft because the frame rate is huge, but it's not that I'm worried about. The thing I'm worried about is when I'm playing it's started to crash as I load minecraft up, and sometimes becomes a little laggy. To me it's worse than my old one. Every other game is fine though. I have everything max with 100fps on BF4 and COD advanced warfare so It's fine with other games. I have a feeling it's the psu maybe but I'm not quite sure?
My specs are Intel core i5 4440
FSP 500w 80+ Gold
+12v1@14.0A
+12v2@16.0A
+12v3@18.0A
+5vsb@2.5A
-12v@0.3A PSU
GTX 970 GPU
Thanks

id say its a powersupply problem as those 12+v rails aren't very strong also have you locked it to V-Sync to relieve stress on your GPU?

Make sure you have latest drivers from the nvidia website.

If the issues only happen in minecraft then check the version of java you have installed is correct, either 32 or 64 bit depending on OS and not both.

Allocate more memory to minecraft.

Delete META-INF in your .minecraft folder.

In windows set pagefile to "managed by the system".


Create a custom profile for minecraft under the nvidia panel and set everything to "use application settings"
