So I finished putting together my build today and everything seemed to be working fine after installing the OS, save for the front two USB 3 ports not working. I had to plug in my keyboard and mouse directly to the mobo using USB 2 ports on the back. Everything seemed to be running smoothly but then I started to smell a sort of stench of burning plastic or rubber after 20 minutes or so. I've come to the conclusion that it's either the PSU wearing in or the CPU/thermal paste overheating due to the heatsink being able to slide ever so slightly as I was afraid of tightening too much. Any ideas as to what may be causing these issues? Any input is greatly appreciated.

Case: Corsair Vengeance C70
Mobo: Asus M5A99FX Pro R2.0
Cpu: AMD FX 8350
Heatsink: Cooler Master Hyper 212 EVO
GPU: EVGA Geforce GTX 760
Memory: Corsair Vengeance LP 8GB (2x 4)
PSU: Corsair CX600M
HDD: Seagate 1TB 7200RPM
Wireless PCI-E: ASUS PCE-N53 Dual-band N600

check for bent pin in the usb ports on the front and check the usb cable and port on the mb. with a pc there should never be any burning smell. sounds like the usb for the front of the case was plugged in wrong and melted.
