Computer crashes to black and BSOD's

I recently installed a new copy of windows 10 on my PC because i bought a new HD, and then tried to install the drivers for my RX-460 card.So i installed the latest 17.7.2 Crimson driver and after installing it i enabled Virtual super resolution as well. So after a couple hours of just browsing the internet and installing other applications i encountered a hang, for about 5 seconds my pc was stuck and then it went to black but didn't shut down completely as my PC was still on, but my monitor was in no signal mode.After restarting my PC again, i went back to doing my normal work, and it happened again, but this time i got a BSOD with the error code: dxgkrnl.sys , so after searching the web on this bsod i thought i might just disable the Virtual super resolution because i had never turned that option on before on previous drivers. And for a while nothing happened and everything was working fine, till this morning, i was again browsing the internet and i got the same thing: hang+black screen. I restarted my PC and checked Blue screen view and it gave me another bsod error:atikmdag.sys

I have no idea what to do now, i am currently downloading the previous version of my driver and seeing if that helps, but if you guys have any other ideas as to what this could be that would be great.

The dumps on both bsods from bluescreenview:

Let's try looking at these 2 sets of reports (wait until it has problems before running test 2 (then recover and generate the report) - but you can start the temp monitor beforehand):

Report Set #1)  Please run this report collecting tool (even though you may not be experiencing BSOD's) so that we can provide a complete analysis: (from the pinned topic at the top of the forum)   http://www.bleepingcomputer.com/forums/t/576314/blue-screen-of-death-bsod-posting-instructions-windows-10-81-8-7-vista/
FYI - I don't often use the Perfmon report, so if it doesn't work please just let me know.

If you have problems with it running it, there's an alternate tool here (direct download link):  https://github.com/blueelvis/BSOD-Inspector/releases/download/1.0.5/BSODInspector-1.0.5.exe

NOTE:
Please zip up the (.ZIP) files - do not use .RAR or other compression utilities. 
.ZIP is the type file that can be uploaded to the forums.

Report Set #2)  Please do the following:
- open Event Viewer (run eventvwr.msc from the "Run" dialog)
- expand the Custom Views category (left click on the > next to the words "Custom Views")
- right click on the "Administrative Events" heading
- select "Save all Events in Custom View as..."
- save the file as Admin.evtx
- zip up the file (right click on it, select "Send to", select "Compressed (zipped) folder")
- upload it with your next post (if it's too big, then upload it to a free file-hosting service and post a link here).

FYI - If we're looking for Event ID 41 errors (unexplained shutdowns), there's more info on that here:  http://support.microsoft.com/kb/2028504

While waiting for a reply, please monitor your temps with this free utility: 

SpeedFan v. 4.5.1 and later (free from here:  http://www.almico.com/sfdownload.php ) can log temperatures in a CSV file:
You may not need to log temps - if uncertain, please ask.

To make it work (log the temps to a file) you have to do BOTH of the below:

1. Enable logging in general: Configure...Log...check "Enabled" then click on OK to save.

2. Enable logging for specific checks: Configure...Temperatures..left click on each sensor, then click on "Logged" at the bottom of the Window (for our purposes we want them all) then once you've selected "Logged" for all sensors, then click on OK to save.

The log will be located at C:\Program Files (x86)\SpeedFan

Naming: log files are named SFLogYYYYMMDD.csv, where YYYY is the year (four digits), MM is the month (2 digits, zero padded) and DD is the day (2 digits, zero padded). If a file already exists by that name, the file that already exists is renamed according to the following naming scheme: SFLogYYYYMMDD-CCCC.csv, where CCCC is a increasing number. The new file is then created with the standard file name scheme.

Notes: whenever you change the options related with logging, SpeedFan starts a new log file.

NOTE:You may want to turn logging off when we're done - as I don't know it's impact on performance or on the system.
