I have a 6 year old desktop and had been watching Netflix when it froze. Let it sit for a couple minutes and then the dreaded BSOD came up. The error/violation (can't remember language) that it gave was DPC_Watchdog_Violation. After restarting it ran ullllltrrraaaa slow. Like every mouse click would take a minute or two to register. Throughout this next bit, it would regularly BSOD and give the same screen and I would have to restart. Even when I booted in safe mode I noticed this slow problem. Google/forum browsing suggested a problems with drivers, so I went through Device Manager and manually checked for updates for graphics, network, and some others. No updates were found necessary. Mentioned commonly were issues with a SATA-AHCI controller driver? I didn't have this driver at all and I tried following instructions to turn on AHCI in the BIOS, but there was literally no mention of AHCI anywhere in my BIOS under any menu option. Back to the graphics driver, I decided to go to AMD directly and download their tool to update drivers (AMD Catalyst Center) and that stated that I needed to update graphics driver. I let it do this, it was taking over an hour and I fell asleep. When I woke up, BSOD! I can't remember if it gave the same watchdog error or not, I was drowsy.
After restarting now however, it failed to boot at all. During repetitive restarts I saw any one of 4 different screens that are attached in the IMAGES zip folder (IMG1,IMG2,IMG3,IMG4). Following advice on forums, I tried tinkering a bit with BIOS, I did the "Load Setup Defaults" to reset it and also updated the BIOS from ASUS. Nothing really changed, still couldn't boot. Finally I managed to create a Windows 10 Boot disk on a USB stick and plugged it and and I am now back in my computer, and that's where I'm at now. I do NOT notice the speed problem I had before now that I booted from USB. I did a disk check for errors on the C: drive to see if the hard drive was failing, but there were no errors. MalwareBytes just found 5 "non-malware" threats that I removed. So currently I need to know what caused the BSOD in the first place and what caused the full crash and failure to boot. Also, because I booted from a USB does that mean I need to continue booting from USB until problem is fixed? Or did that boot repair it?
I should mention that previous to all of this I had replaced the CPU cooler and fan, but it was working fine for a week, much cooler temperatures, and had also used a torrent software for a .mp4 file, which I have uninstalled out of spite now because of these problems.
Additionally, when I did the SysNative scan, it eternally paused at one point (with App9 and App10 windows open) and just kept spitting out "Waiting for Tasks to complete" The instructions said to close it if this happened and that's what I did. (IMG5 in the IMAGES folder shows what I mean). I also included a Speccy snapshot if curious (IMG6)
Sorry for no tl;dr version. I'll be around to respond and update any suggestions that people have. Hopefully on this computer and not through my laptop.
EDIT: Also I should mention that in the guts of Speccy I can see that for the C: drive, SMART is reading GOOD on all fronts... which would suggest I didn't experience a hard drive failure?
