I don't remember when this problem started maybe 1 year or more ago. To be more specific when I open my computer it seems fine for 5 seconds, then it starts getting worse by stuttering for no reason ( even on desktop screen with no major programs running ex. google chrome, games etc. ) or even freezing the whole screen/computer making those weird bzzzttt.. noises and restarting or even diyng for like 5 - 30 restarts. It sometimes doesn't even boot up and I'll have to try again in like 3 hours or so. I tried having a clean windows installation and formatting my computer but nothing worked. I tried updating all my programs and drivers but didn't work either... I also tried putting thermal paste to my cpu... Don't know whats wrong but maybe you guys can help me since it's pretty a annoying problem that I have on my computer for over a year!
note/edit: ( it also decreases overall perfomance somehow ) Some information about the topic (img)
