BSOD while gaming with Chrome open, 0x0000007f & 0x0000001a

Hi, recently I've been having rather frequent (at least twice a week) blue screens. I wouldn't be able to tell you when they started, however, since previously they weren't such a big deal. The only consistent factor that seems to exist when the blue screen happens is that I'm either playing Dota 2 or Osu!, and have Google Chrome open on the side (two monitors) with at least 4 tabs.

After a quick google search and checking my logs with BlueScreenView, the number of dumps I have doesn't seem to reflect the number of blue screens I've gotten. Since 8/14 (the last log in there), at least 4 blue screens have occurred: Twice while playing Dota 2, Once while playing Osu!, and once while I was about to shut down my computer.

As a side note, I used to have a habit of leaving my computer on 'sleep' mode for prolonged periods of time for sake of convenience, but have since been shutting the computer down properly. I believe this may have been the underlying issue to many of my problems; but hopefully you guys will be able to help me out!
