Random spikes in disk usage while gaming or using chrome

-Sorry for my bad english- I got a cheap laptop that I recently factory reset (is that how you say it?). As the title says, every 5 mins or less, above all while gaming i get dramatic frames drops due to these spikes in disk usage. First thing I did was disabling windows updates and that helped a bit. I also ran a test with windlg,either quick and long tests were negative. I read tons of threads on disk usage but most of them are about constant 100% usage while very few are isolated spikes, furthermore no resolutive solution was ever present in them. Uh the disk drive is an hdd 1Tb. I don't think is a ram related problem since 8 gigs seems enough to me for most games (like League of legends). Also no process in the taskbar seems the culprit during these spikes. Processor and ram usage are less then 60% all the time. So...what can i do?

PS: its my first thread, you guys can see the specs on my profile? also windows version is 1903 (build SO 180362.959)

For Google Chrome, you could Disable the preload pages and disable any extensions that are not needed. For gaming, check if your drive has any power saving characteristics, you would have to switch that off when you are gaming.
