So the other day my computer started getting seriously laggy, like in everything. There is a big delay when typing and when letters appear, I can't load videos of any kind loading websites takes way to long compared to how it should It's just terrible.. My computer auto defrags every wednesday, I have run malwarebytes 2 times now I run ccleaner, I gave my computer a nice thorough cleaning, I have done everything short of check for serious hardware issues, right now my CPU usage is anywhere from 50% to 100% while doing very little but the fluctuation seems to have to effect on the lag, I chalked it up to heat because my apartment is like a sauna right now, just looking for ideas on what it might be, maybe just set a fan up next to the computer? I have no clue, thanks in advance.
