Systems hangs for a while on files handling

Again you have to go through basic troubleshooting steps. That means to run a check disk, replace SATA cable if not a laptop, run a S.M.A.R.T. test, reset the bios and replace the CMOS battery if the machine is over three years old. Also have seen controller chips go bad even on not even a year old machine.

Never just think that it is Windows, because everyone automatically assumes and blames software before checking out hardware for problems.

It would be like taking your car into a mechanic and telling them that the car does not start and they ask you if the dash lights come on when you turn the key, or the vehicle tries to turn over, along with when and where did you last put in gas and/or change the oil.

Simple questions give simple answers and it is your machine, which means that you are going to have to go through the basic troubleshooting steps first, before looking at something else. That includes resetting the Page File, turn off Hibernate if it was not already turned off.

I appreciate you try to help mate but I must be honest, there is no logic behind your answers once I provided multiple clues that show there is no problem with the hardware. Same goes for the other user that answered.
And all due respect, advising someone else to replace storage drives without a single prove that they can be faulty, is negligent to say the least.

Anyway, after some more testing I got to the point where I am 99.9% sure the problem is related to the OS and the SMB shares, but that's something I'll keep debugging somewhere else.

You came here for help and knowing that hardware is the the first level when looking at problems and that the OS and shares are way down the road, is how troubleshooting works. I have been doing this stuff for over 35 years.

Do you think that if your car does not start, that the mechanic is automatically replace your engine, without properly diagnosing at the first level of check to make sure there is fuel, oil, battery is not dead, before looking at something deeper like the computer. That is why when a person comes on here and is adamant that every answer is wrong, you are going to get asked many times if you did the very first steps you were asked to do.
