For some reason my computer starts to lag behind in everything i do after its been working for about 30mins to and hr, I've tried everything; scanning for viruses (with norton) cleaning it, moving it to a different place for better ventilation, and still the problem persists, any suggestions? This has been going on for a couple weeks now
