For the past 3 months, I have been trying to solve this problem. My computer randomly spikes every 10 minutes or so and it uses up most of RAM or CPU causing me to fps in all of my games. I tried system restore and all but it wouldn't go away. I think it might be a program that i have downloaded but i have uninstalled all unneeded programs yesterday and it is still spiking. It might be possible my computer is infected with a virus.
