My almost one year old laptop, Lenovo G50, I5, 1TB HD, 4GIG RAM, running windows 8.1, has recently become much slower than usual???? I mainly use it for light gaming and music and my wife downloads movies on her phone which she then transfers to the laptop to watch. I ran a virus scan with Avira and it found 200+? I also ran Malwarebytes and it also found quite a number of malware? I then ran Registry Mechanic and it also found and fixed a gazillion errors......??? I then proceeded to do a hardware scan with the built in checker, and got a SMART warning the first time i ran it, but the scan indicated all hardware functioning properly??? When i ran it again two weeks later, no warnings and all HW reported in order??? Thing is after all this laptop is a bit better but still very slow?? Especially on startup??? Any ideas what else it might be or what i can do to check????
