This morning my computer was running perfectly. This afternoon i went over a friends house and we built a computer for him. I took my computer over to use as a model. We worked in his garage for a few hours and got it all put together. Then i get home to find out that my computer is laggy now for everything I do from games to opening folders to even just browsing the internet. I have also noticed that on the task manager it shows that any process im running be it skype or a game takes up about 50% of my cpu when it used to take like 5% at most. The internet does this too, a single open tab on chrome takes up about 30%. I really have no idea what caused this. I don't think the specs are necessary, but if needed ill give them.
