What's causing this BSOD (0x50, 0x1a, 0x7f)?

Oh, I've noticed another difference between then and now. My laptop usually updates and creates another drive in the "My Computer" section (I think it was a BIOS Update), but it didn't after the factory reformat...

If you want to see the latest dmps, I'll post them here also

This line is still showing up. You said you are still running Windows Defender right?

Haven't seen a BSOD after downloading and installing the standalone file for the graphics driver (Intel HD Graphics 2000) to update it manually.
(Been using may laptop for a total of 6 hours)...hope I fixed it..

After I manually updated my display driver, an outdated update (oxymoron lol) popped out on Windows Update. I installed it, but, unsurprisingly, the "update" failed. When I pressed the shut down button, a BSOD came up. So maybe the issue really is about my drivers. I turned my laptop back on and used the standalone latest installer to fix the errors. Never got a BSOD ever since. If I don't get a BSOD from today until tomorrow, I'll mark this as "solved." Thanks for all the help!!!

I'm about to mark this as solved. Thanks for the help again! I hope those RAM problems won't bug me in the long run...I'm probably going to get a new laptop after I graduate high school anyway. It's safe to assume this rig is pretty beat up. TY!

May day may day! A bunch of BSODs just showed up. I don't have time for this right now (I'm sure you don't either). I'll post the stuff tomorrow...

It's been a long time since I've replied (I apologize), and it seems like I've solved the problem after a number of experimentation. I downloaded this program where I can instantly scan all of my drivers and update them automatically. I haven't gotten an error since then, and my computer has been running at a typical performance (no crashing/not responding programs). The only thing at the back of my mind is the memtest that I did showing errors. Should I just ignore that?

(I haven't tested my sticks individually)
