BSOD's when CPU is under full load. Error code varies.

[ezbie]

I have had several of these and tried analysing the minidumps myself but I simply don't understand the information in the dumps.


I already let Memtest86 ran for 4 hour, 6 iterations, no errors detected.
Also did CHKDSK on my C drive, nothing found. My install is on a SSD disk that's almost new, no smart errors detected.
CPU was previously slightly overclocked. I disabled all overclock and although BSOD's aren't happening as often now, the PC still crashes when underload, it justs takes longer or needs to be under heavier load now.



Additional info: I ran sfc /scannow and it found several files were corrupted and was able to fix all but 1, named "hp8500at.dll". I got that file from a working PC, used windows search to find it under the C:\Windows directory. The file is present in more than one location, I took ownership and replaced it in one of the locations, after that it doesn't show up in Windows Search anymore . I ran SFC /SCANNOW again and now it says "0000033f Hashes for file member \SystemRoot\WinSxS\amd64_prnhp005.inf_31bf3856ad364e35_6.1.7600.16385_none_30e9a6119eda44e5\Amd64\hp8500at.dll do not match actual file [l:36{18}]"Amd64\hp8500at.dll"

The problem now is that I can't find the path for the "Actual file". Anyways, I gave on fixing this file for a while. It's an HP printer driver and I don't have any printer, so I think it's unlikely it's the cause of the issue.


Here's a link of my minidumps: Minidump.zip - Google Drive

Have you tried plugging your RAM into other slots, booting your computer with only one RAM stick, and swapping your RAM for another?

 

[ezbie]

no, I didn't try any of that, although prior to installing windows 7 I had my single ram stick in another slot. I was having BSODs too with windows 10, only did they happen randomly, regardless of cpu load.

Now, to my bitter surprise, after shutting down the PC normally yesterday, the PC turns on now but shows no video, regardless of the video output I use. I tried changing the position of the Ram stick and, nothing...
Most strange of all: I remove the ram stick, the PC seems to ignore it. All components start, the CPU fan spins...


seems like I have a defective motherboard.

Hi, I'm here in need of some help again.
I replaced the motherboard and the CPU, as the old motherboard simply fried itself, seems it was at least partly because of it that I was getting BSOD's.


Now, however, I've just got another BSOD. It's pretty lame actually, it shows "mouhid.sys" as the issue. That's windows default mouse driver. My mouse isn't anything exceptional, should I format this computer for good, so I can possibly get rid of all these errors?
