It looks like the "wlan" as mentioned in Latency Mon is the culprit. However, it may not actually be the LAN, but the traffic on the LAN.

Look at what is still active, as one of those could be what is causing it. What is in startup is the first place to look.

Do you know how to track what is causing this ?

At startup there isn't much

What motherboard do you have? If you have a Gigabyte Motherboard and have the EasyTune installed, that can cause the problem, although that has nothing to do with LAN/Internet.

An installed program that has an automatic updater is a possibility. I installed Google Chrome and was having problems with my recording studio. I ran the DPC Latency Checker and had high spikes. I uninstalled Google Chrome but still had the problem. I found when I installed Chrome it automatically installed a hidden Google updater program. I had to ultimately manually edit the registry to get rid of it.

If you have Dual LAN's on the motherboard (what is the actual motherboard?) try switching to the other Ethernet port.

I would also run a spyware program. Run a complete scan with Malwarebytes.

My motherboard is a Pegatron

I don't think google is causing this because i used it for a long time and this only happened since the last time i installed windows.

A scan is a good idea.

Do you know if I save my personal data and completely destroy the hard drive data, is there a chance that problems like this still happen?

The Pegatron motherboard suggests this is a HP PC or at least the motherboard from a HP??

One other thing I notice. You have Win 7 64 bit, but only 4GB of RAM. The main reason to use a 64 bit OS is that it will address more than 4GB of RAM. A 64 bit OS requires more basic memory than a 32 bit and thus less memory left for programs. This is probably not your problem, but something to consider.

Another thing, it shows the NVIDIA as the "Audio" and not your PC's sound card.

If you save your personal data, and there was some type of infection or malware, and it was not removed there is a chance it can re-infect when the data is restored. If you decide to do a new "clean" reinstall, run the DPC Latency mon before any applications are installed (just the basic Windows and internet) and see how that works. If its OK, start installing applications and check after each application install. I know this is time consuming but looks like what is needed to resolve this.

I won't be able to respond until tomorrow. I'm off to a music playing job this evening (I'm a musician)

Possible you will install the same stuff and it will be there, never know without trying. Better to first find why and do as you wish later. But that's me.

This is the brand of my computer https://www.wortmann.de/

The computer came with only 4 Gb of RAM and Win 7 64 bit, dunno why (when i can i'll want to get more RAM)

For Audio, i always did the same thing when it came to install drivers and such idk if i was doing something wrong

Tomorrow i might get a external drive so i can save what i need and destroy the rest, i've had some problems with the hard drive so i feel that cleaning it up might help. Still it would be helpful to find the reason why i have these DPC spikes. It might help me later or someone else, who knows

-Scan running-

Yeah if i don't find it before i delete everything after that when i install windows i'll have to check my DPC constantly to see if i install something that is making these spikes

Edit: I wished that windows 10 would come out tomorrow as i plan to get it, at least like that i would take out possibly 2 problems at once

Quick question ^^''

I wanted to see what i needed if i was going to destroy the hard drive data, and i decided to use DBAN "Darik's Boot And Nuke" but i would like to delete the partitions too (partition table i think). What i mean is after using DBAN i would have the entire hard drive as unallocated space, do you know if it does that ?
