I have currently a low spec home server with core i3-550 and 10gb ram. I am hosting two virtual machines and http file server on it.
Lately, when i tried moving files bigger than 2gb, the computer gets extremely slow, exporer crashes and then a it bluescreens. The bsod stop code (reason) is different everytime.
I have an sata ssd and two hdds in the server. The ssd is 1 month old (has 95% in crystaldiskinfo) and the hdds are not really new, but have still perfect condition of the sectors.
I have never had this problem, it started three days ago, when i was copying a virtual machine from one folder to another on the same ssd.

Here are the full specs:
CPU: Intel core i3-550
GPU: Nvidia Geforce 210
RAM: 10gb, 4/4 slots used, same manufacturer
HDDs: SSD-Kingston A400 250gb, HDD1-Seagate Barracuda 1tb, HDD2-Samsung 2.5 form factor 250gb [all are in good condition]
OS: Windows Server 2012 R2

The average hardware usage when idle [vms and hfs running]:
CPU: 8%
RAM: 7.5/10GB
SSD: 1%
HDD1: 1%
HDD2: 1%

The average hardware usage when copying files 2gb and bigger:
CPU: 40% max.
RAM: 8.0/10GB
SSD: 40%
HDD1: 1%
HDD2: 1%

I have tried ram check and ssd check, both were without problem
The OS completely freezes after 20 seconds after i start moving the files, then explorer crashes and then it bluescreens and my vnc session disconnects
I did a recording multiple times using my phone on a physical monitor connected to the server using vga and saw what i said every time

Screenshots from vnc:
The file copying started [vms and hfs are not running]: https://ctrlv.cz/KbwT
About 1 minute after copying started: https://ctrlv.cz/VqZk
VNC disconnects: https://ctrlv.cz/mSEl
The server automatically restarts after 1 minute: https://ctrlv.cz/EGgO


I appriciate every help :)

How full is the SSD and the 2 HDDs?

PSU: make, model, wattage, age, condition (original to build, new, refurbished, used)?

Look in Reliability History and Event Viewer.

Either one or both may be capturing of error code, warning, or even an informational event that occurs just before or at the time of freezes and crashes.

SSD Usage: 120GB free of 250GB, You can see it on the screenshots :)
HDD1 Usage: 550GB free of 1000GB
HDD2 Usage: 220GB free of 230GB

I bought the PSU off Facebook marketplace and i don't know how long have been the previous person using it, but i have it for 3 months.
PSU: 600Watts
I'm sure psu has nothing to do with it, because as I said, I've had it for 3 months and the problem started 4 days ago. I have been copying files quite often since i have the server. I am quite sure that the problem is the ssd, because it is on 100% usage a second before the bsod appears.


I will check the event viewer later, as i am not copying anything right now [I was copying some files 3 hours ago, though the ssd usage was on 100%, the bsod did not appear]

In 1 and 2 I am seeing a bit of a pattern in the errors particularly in the Source column.

Source being something other than Service Control Manager and the red errors being a bit mixed with mostly "Application Error"

Not certain about which ones preceded or corresponded with the slowness, crashes/BSOD's.

However, my immediate thought is corrupted or buggy Windows files. Could have happened during the VM copying process.

= = = =

Try running "sfc /scannow" and "dism" via the Command Prompt.
