[SOLVED] PC freezes from heavy network load

[20GK]

Hello everyone. This is such an unpleasant problem.
When a large amount of data is loaded on the network, the system begins to freeze, wheeze and crackle sound. At that time, the processor, RAM, GPU are idle at a minimum except for the network.
What could it be?

On one forum I saw how a guy decided to replace the PSU.
Demonstration video below.

Is "SSD 120GB M2 NVME (included Windows 10 21H1)" your boot drive?

How full is the drive?

Try using Resource Monitor and Task Manager to observe what your system is doing.

Use both tools but only one at a time.

Watch first without doing anything.

Continue to watch while doing light work or browsing.

Then, leaving window open, download a large amount of data on the network as you usually do.

See what changes.

Note: it appears that you are doing some of above per the second link. However the display moves too fast for me to see anything.

And remember to look in Reliability History and Event Viewer for error codes, warnings, and even informational events that occur when the freezing, wheezing, and crackling occurs.
