Hi everyone, this is my first post on here, so sorry if this seems kind of amateur. But I had just recently built my first computer and it runs prett good for the most part. The only issue I have is with GTA V where it will run a solid 60fps for a while, but then it'll drop to about 30-40 at random times, usually more so when I'm driving around. Someone had mentioned that the VRM in the motherboard is overheating and is causing the CPU to thermal throttle. I've looked at other boards just to see where they usually lay, but on mine, it seems nowhere to be seen. Am I missing something or is it built different or what? I'll put a link to a picture of it. Please help, thanks.
