I have a Lenovo yoga 2 that I have had since I came to college roughly 2 and a half years ago. It has slowly lost processing speed and the wifi drops more often than the beat in an edm song. I want to take my laptop and smash it against the wall because simple browsing and watching YouTube videos is like asking a man with no legs to walk. No I do not visit sketchy sites that have put malware in my computer. Yes I do have mcafee security software downloaded which I have the premium version of. The only other major programs I have downloaded is Microsoft office, skype, and steam which I uninstalled all games I previously had downloaded. Wifi connectivity is my major issue and whatever y'all can do to help me would go a long way thanks.
