Hello!
Yesterday I spent the evening updating drivers and such.
1) As for the graphic driver, I had to uninstall the most recent update and revert to the one I had, it made me get random spikes about 5,000 μs even when the computer was idle (around one every five minutes). With the current one, I'll get a random huge spike from time to time, but it's isolated and apparently not followed by more big spikes.
2) I updated the Ethernet driver and all the other devices that appeared below the Intel(R) Ethernet Connection (2) I219-V are nowhere to be seen as in the picture I posted in my previus post. Picture below.
Regarding the Intel update, it seems to have lowered the latency a little bit, however, Ndis.sys and Tcpip.sys sometimes still go up to 200 μs in Latencymon's "Highest reported DPC routine execution time" from time to time, yet I was told that is normal because I have an active connection.
3) Audio drivers were up to date, I don't notice any noticeable change with previous or new drivers.
4) I don't think I have a Wifi driver, so, that must be out of the question.
I add a latencymon screen cap, as well as the reads on the stats section.
Latmon stats:

MEASURED INTERRUPT TO DPC LATENCIES
_________________________________________________________________________________________________________
The interrupt to DPC latency reflects the measured interval in which a DPC could execute in response to a hardware request from the moment the interrupt service routine started execution.
Highest measured interrupt to DPC latency (µs): 276.766805
Average measured interrupt to DPC latency (µs): 2.460206

Highest reported total ISR routine time (%): 0.109743
Driver with highest ISR total time: dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation
Total time spent in ISRs (%) 0.12650
ISR count (execution time <250 µs): 205587
ISR count (execution time 250-500 µs): 0

REPORTED DPCs
_________________________________________________________________________________________________________
DPC routines are part of the interrupt servicing dispatch mechanism and disable the possibility for a process to utilize the CPU while it is interrupted until the DPC has finished execution.

REPORTED HARD PAGEFAULTS
_________________________________________________________________________________________________________
Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.
Process with highest pagefault count: none
Total number of hard pagefaults 0
Hard pagefault count of hardest hit process: 0
Highest hard pagefault resolution time (µs): 0.0
Total time spent in hard pagefaults (%): 0.0
Number of processes hit: 0

My friend keeps insisting that I should either ditch the Nvidia card for an AMD one or that I learn to live with this, because it's normal. Do you think I am just overthinking way too much?
Thanks for your support so far!
