As stated above. I have no issues with gaming.
Intel I7 4790
AMD R9 380
8 gig DDR3 1600 ram
I have run multiple stress tests on the Graphics card and I have had no luck replicating the issue.
Microsoft Edge, as well as Google Chrome both crash, I am unsure as to the particulars of the site content that causes the crash, however running integrated graphics, or without drivers installed eliminates the crashes.
Have you tried disabling "Hardware Acceleration" in display settings?
