Games Freezing With Buzz Loop + AMD Display Driver Failed Error

  iRealizedKing 22:06 03 Apr 2015

I build a computer system not too long ago and upgraded it's CPU and GPU yesterday. Here are the specifications:

Motherboard: Asrock FM2A55M-HD+ Processor: AMD Athlon X4 860K (Upgraded from A6-6400K) RAM: 8GB (2 x 4GB) Vengeance Gaming 1600MHz Card Graphics Card: XFX Radeon R9 270 Double D Edition (Upgraded from Integrated AMD Radeon 8470D Hard Drive: 320GB Seagate 7200RPM Case: Zalman T3 with 2 Chassis 3-PIN Fans PSU: Aerocool AP-450PRO 450W 80+ Bronze

I am having an issue where when I start to run graphic-intensive games like Just Cause 2 and Sleeping Dogs: Definitive Edition at Medium or High settings, about 10-15 minutes into gameplay, the entire operating system will freeze, and the game will produce a buzzing sound. The computer will remain unresponsive until I press the reset button on the computer case or turn it off and back on manually. I have read many threads, where they all seem to suggest that the issue is with the graphics card overheating, so I decide to monitor the temperatures using both SpeedFan and Hardware Monitor, when the computer would freeze, the temperatures of both GPU & CPU would report being at around 60C. I ramp up the GPU & CPU Fans to 100% only to be reported the same temperatures. The case usually feels quite hot, and for some reason I am unable to control my 3-PIN Chassis Fans from SpeedFan, so I hooked up the Fans to Molex connectors to have the run at constant full speed but temperatures aren't Changing. This isnt happening with low-res games like Minecrcaft, although, those games and simple OS applications have an issue of their own where the screen monitor will just randomly black out, then a popup will appear saying the AMD Display drivers have stopped working and recovered succesfully. I have tried wiping out all the drivers then installing the latest drivers from AMD's sight, also making sure I have disabled onboard graphics in the UEFI, still to no avail. These issues are slowly becoming more and more frequent and I dont know why. I had high hopes with overclocking these devices, but being unable to get past the first cutscene in sleeping dogs in Low settings with a mid-high range graphics card like the R9 270 (No X) is dissapointing. Any ideas what might be going wrong?

Just a thought: A 450 Watt PSU is a bit close to the lower part of the spectrum.

Do you reckon its an issue with the PSU? Not enough power being drawn or anything? PS. Im running Dual Monitors
