RX 480 will sometimes sit at 100% activity when idle. Anyone else have this issue?

My GPU will stay at full load randomly (about 1 out of every 5 boots) after I exit video game, need to shut down then turn on again to get it back down to 0% restarting does not help. My CPU usage hovers anywhere between 0-3% during this time as well as the GPU memory clock mostly stays at a low 300MHz vs 2000MHz while under actual load, so I don't think a bitcoin miner or any virus is the culprit, also nothing unusual under task manager. Running the latest AMD driver 16.8.2, I've had this issue with previous drivers as well. Haven't found any info elsewhere. Any help will be appreciated.

Here's my rig:

Asus Z97-A mobo
4790K
850 PRO SSD
RX 480
G. Skill 2400 MHz RAM
EVGA G2 Supernova Gold 750W PSU
 
Solution
After a clean driver install as suggested, try disconnecting from your router to rule out a bitcoin miner. If the GPU usage still goes up to 100% when idle, then you can rule that out (I think).
