Hey! I have quite a serious problem that I hope someone can help me with. I'm not really sure when it's started, but it's been like this for atleast 6 months.

Sometimes, my computer starts to lag extremely much, to the point where it's impossible to do certain things. The spikes only last for about 10 seconds to a minute. But they're really really annoying.
Any idea what could be causing this? All my drivers are up to date.

This picture shows that Firefox most likely is the culprit, but it doesn't matter which browser I use, I still get lag. Even with cookies cleared, cache cleared, fresh install etc.
I've also made sure that I have no viruses or malware on my computer.
