DDR3 RAM Errors

[qacuho]

Hello everyone,

I hope you're all well. I was hoping you could help me out with something. I have been having some problems with Windows 10 locking up, requiring a reboot (screen will just freeze up, no BSOD), at seemingly random times, though some have cropped up more than once (and therefore, seem less random): 

• ALT+Tabbing away from a fullscreen game of Minecraft: Java Edition
• On the Windows 10 shutdown screen or just before it gets there (after clicking shut down)

Anyways, I started to suspect memory might be the issue. I ran the Windows Memory diagnostic tool first, and it detected issues, but didn't have much to say about it. So I ran MemTest86 and it also identified several issues. The report is attached. My specs are as follows:

• CPU: i5-3570k (no overclock)
• Motherboard: Asus P8Z77-V (Rev 1.x)
• RAM: Mushkin Blackline 991995 (996995) (2x4gb running usually at 1333MHz, but the test seemed to run at 1600MHz)
• PSU: CoolerMaster 750W (relatively new)
• GPU: AMD Sapphire Radeon Pulse 5600xt
• SSD: 120gb SATA3 ADATA
• HDD: 2tb Seagate
   

I am thinking the RAM is probably bad, given the test results, but I would like to determine if I need top replace more things. Depending on what people say, I might just bite the bullet and simply purchase a new motherboard, CPU, RAM and get a nice upgrade out of all this. I realize most of my system is quite old, but it seems to work quite well for me when it does work (it will go anywhere from 5 minutes to many hours without freezing up, even in games demanding 80+% GPU and much of the CPU). It's worth noting as well that my main PCI lane seems to also be broken (an unfortunate accident which involved kneeing the case, which put pressure on the DVI port of my GPU, crashing the computer instantly), so it's running on the secondary one, which seems to work much better. As you can see, this system has been through a lot! I am just getting back into gaming on a casual basis, especially with being indoors so much right now! I just want it to work reliably. I did have a hard drive fail on me a few years back, which caused a very similar freezing issue in Windows 7, but seemed to go away when I replaced it. At the same time, I also replaced my crappy 430W PSU (my old graphics card was slightly less power hungry than my new one), but it's possible it may have affected more things if that's in fact what brought down my HDD at the time. Lesson learned: don't use a crappy power supply that comes with the case! But all I can do now is learn from it and move on.

Please find the attached report. I realize I may have not provided you enough information, my apologies for that. Please let me know what I should provide or what tests I should run further and I will be happy to, I'm a bit new at troubleshooting.

Any help would be much appreciated.
