Mild burning smell from pc

[Hemerhidger]

So for 2 days I've smelled mild burning coming from my pc. Last upgrade for my computer was about 2-3 months ago. The smell also seems to be random, sometimes it's stronger than some other time. I think my gpu and cpu are a little bit hotter (idle and when gaming) than before. http://imgur.com/3hBjnDX Here's what HWmonitor says. Although my computer has still worked fine I'm worried. Any help would be appreciated

Oh and also the gpu is XFX and PSU is XFX PRO550W

I doubt it is the CPU (although your high temps are getting close to max). With the fans circulating air, it is always hard to tell where smells are coming from. But the usual suspect for burn smell is the PSU. The next most common is the graphic card. The card's 77C is up there, but still well in the safe zone. If something is cooking on the card, it is not the GPU.
