I've been using a newer MS Office Suite often lately, as well as Acrobat Reader, my computer bogs down and stalls for way too long often. If it falls asleep, forget about it, can be 30 minutes with cpu light lit up. Could more memory solve this? Here is what I found on my computer Here are specs I found from manufacturerLenovo C460 All-in-One | Entry-Level All-in-One PCs | Lenovo UK Think I can another 4gb and would that solve the stalls? DDR3 1600mhz ?
