Whea_Uncorrectable_Error, freezing, dark screen
Forums ate my first, lengthy post, so that's cool. Gives me a chance to pare it down, I guess.
This problem's been going on for about three weeks now. Laptop is Acer Nitro AN515-54, Windows 10 (build 19045.2728), about two years old. When the laptop is shifted, bumped, sometimes when the screen is angled differently, it does one of three things: it freezes completely, the screen goes backlit black (but my repair guy tried an external monitor when this happened and said the whole system was frozen, because nothing happened), or it does this BSOD.
It first happened while I was watching a video in VLC, which scared me because I cannot afford a new motherboard, which is what I'd need if it was the CPU or GPU. Then it seemed like it was mostly happening when I had a game open, which still looked like a graphics issue. I took it to the repair guy, he opened it up, found that the thermal paste on the CPU and GPU had been burnt, and the fan had a huge wad of animal hair in it. He fixed those things, and I took it home, but it was still doing the thing. Through testing via usage, and running tests at home, I thought I had it narrowed down to my secondary hard drive, an HDD (the primary drive that the OS is on is an SSD). But I just ordered a new one, waited five and a half hours for it to clone over, installed it, booted, and it almost immediately bluescreened on me.
Things I've run to test:
- MemTest86 (fine)
- Windows Memory Diagnostic (fine)
- Crystal Disk Info (fine)
- Intel Processor Diagnostic Tool (fine)
- chkdsk on the second drive (twice; it found and fixed some things both times)
- sfc /scannow (on the second drive, it found some things but couldn't fix them)
- Acer Care Center tests for memory, battery, hard drives (fine)
When this first started, the string in the upper left of the bluescreen (which my repair guy said isn't usually where that info is?) was different, and I posted on r/techsupport about it and the one person who replied said it pointed to something wrong with the CPU. I have no idea how accurate that is, or what this newer one means. The laptop was running at an average of 190-200F during games, for months, so obviously it's very possible that some other component got cooked, but I don't know what. I tried BlueScreenView, and because the bluescreen I'm getting just sits on 0% until I hold the power button down, it's useless, because no dump files are ever generated.
I'm seriously at my wit's end with this. I'm disabled, I can't work, and my computer is my life, I spend most of my time awake playing video games, writing, and chatting with friends. My laptop is usable, as long as I move very carefully with it, and considering I have two dogs who like to come in and wrestle on top of my legs in my bed, that's not always possible. If anyone can help or provide insight, I'd be incredibly grateful.
