About 5 days ago whenever I was playing a game I would get these random lag spikes and its been going non stop. I asked if anyone else on my internet was having these issues but no one else had them. I did a speed test on my computer and compared it to another computer. I was getting around 40mbps and the other computer was getting 250mbps. I thought the problem was maybe a bad port on my router so I switched where each ethernet cable was plugged in yet my pc was still not at the same speeds as the other. So naturally I thought it was my ethernet cable. I bought a new cable plugged it in, ran the speed test, and nothing changed. I looked into it and found a command line that fixed my slow speeds. I thought that would fix the problem but when I was playing a game I still got the lag spikes. That's where I stopped and came here for help. My best guess is that my ethernet port on my computer is broken but I really don't want to buy a whole new motherboard. Hopefully there's something I'm missing that will fix the issue.

PC SPECS
CPU: i7 9700
GPU: GTX 1060 6gb
RAM: 16gb ram viper patriot
MOTHERBOARD: MSI Z-370 A PRO
STORAGE: 1tb wd blue hard drive, 2tb seagate hard drive, 120gb ssd sandisk, 240gb ssd sandisk
PSU: EVGA 500 BQ


TLDR: Switched cables, switched ports, fixed internet speeds, yet I still have lag spikes.
 
update the lan driver

which command line did you enter to get better speed?

is the firewall on private and not public?

update the motherboard´s BIOS

run userbenchmark.com and post the http link of your result, e.g. https://www.userbenchmark.com/UserRun/28977730

Reset the BIOS by jumper clrCMOS or JBAT or similar (eventually you will have to set the bios priority correctly after that)

check windows integrity
open the command prompt as administrator and type DISM /Online /Cleanup-Image /RestoreHealth

clean boot

check the memory by running memtest.org usb autoinstaller (bootable USB flash drive)

check the hard drive for errors with its manufacturer´s tool

eventually use ddu uninstaller and reinstall the latest graphics driver
