My FX-8320 was doing just fine this morning and in the seven months before that. Temperatures would max at 45-50, idle at 25. Today I got a new GPU, switched from a Zotac nvidia GTX 650Ti to a Sapphire Dual-X AMD Radeon R9 270X. In the installation of drivers and such (which was probably rather strenuous) again, it was fine.
Now that the drivers and utility programs have been installed, the CPU is now idling at 30 (when absolutely nothing is happening) and reached 70 just while I was typing this. On three instances when the CPU is doing some heavy work now (playing Dota 2, trying to install CS:GO etc) the screen will freeze, and will emit a buzzing noise (likely a loop of the sound it was producing in the last 10ms or so). I have since hoovered out the computer and cleared the dust filters and although it hasn't done that again, and the temperatures have dropped by around five or so, they are still alarming.
One thing that I've noticed is that the minimum clock has changed from around 350 to 1350, which appears to be a feature of the Catalyst control centre (it won't let me put the minimum clock below 40% of the maximum). Does anyone think that this could be a factor, and if so how do I over-ride it? And is there anything else that could be a factor and how would I fix it?
Edit: Specs might be helpful
