Okay So I just got a new Lenovo y40-80 today and a few hours after I'd have been using it and playing tf2 tf2 froze so I turned it off and back on again and I started up tf2, the game started but when I was finding a match It froze again and I restarted my computer again I clicked task manager and with no programs open other than the ones running in the background I was at 99% or 100% hard drive usage. I have a 1tb 5400 rpm hard drive so I don't know what the hell could be wrong. Please help I need to know what's up.
