memory - Frequent BSODs on Windows 7 Professional after replacing Graphics Card (worked fine for ~2 weeks prior)

My computer died around 3 weeks ago due to the Graphics Card failing (Asus Direct CU II 7950, an old 1TB Samsung HDD also failed to power up after this) and just 2 weeks ago we replaced it with a new R9 390. It was working fine for about a week, but recently we've received 4 BSODs in the past 3 days. The first 2 were 0x0000000A and 0x0000001E and after the BSOD, one of the RAM modules stopped being detected (resocketing fixed it).

I was going to run a memtest this evening, however during operation I got 2 more BSODs (relatively quick succession), one being 0x0000003B and then 0x1000007E (BlueScreenView is pointing to hal.dll and Wdf01000.sys for this error). I am not really sure what is wrong with my computer right now, and I need help solving this.

If this is RAM, I intend to run Memtest later to verify, however if it is a driver issue I don't really know how to pinpoint what driver is causing the problem. Hope someone can help shed some light on this. For my system specs:

• Mobo: Asus Sabertooth 990FXA


• Processor: AMD FX-8320E


• RAM: 2x G.Skill 8GB DDR3 1333Mhz


• HDD: 2TB Seagate, 1TB Seagate (with windows), 160GB WD


• GPU: AMD R9 390


• PSU: Coolermaster Silent Pro 700W

The only recent driver change I've done is uninstall the display driver completely (AMD clean uninstaller tool) and reinstall Crimson 16.3.2. I have had no other system changes during this time.

The previous 3 BSODs were kernel dumps so I cannot really upload them here but I will upload the latest (0x1000007E) BSOD dump here once someone tells me how (as I don't see an attachment option here). I really hope someone can help me with this really big problem.

Thank you very much!

Update: Used DDU to reinstall display drivers, still ended up getting 2 more BSODs:

• KMODE_EXCEPTION_NOT_HANDLED (0x0000001E) pointing to CompositeBus.sys and ntoskrnl.exe


• NTFS_FILE_SYSTEM (0x00000024) pointing to Ntfs.sys, ntoskrnl.exe and usbccgp.sys

Running a memtest now, hopefully this is really just a RAM issue.

Update 2: Ran memtest and it didn't detect any errors, ran a chkdsk as well and sfc and no errors from them either. Does anyone else have any suggestions perhaps?

Update 3: It is worth noting that the BSODs only happen when I start a game (Dota 2, Fallout 4, Batman Arkham Knight, etc). During normal use (e.g. videos, music, work or browsing) I experience no bsods, but the moment I start up a game it will bsod within a few minutes
