We've been using an Emachines W4685 with Windows XP, please don't stop reading
, for years but we're desperately needing to upgrade as it freezes frequently, it's painfully slow, sound no longer works, Chrome won't even allow me to go to a site from the search bar on yahoo or Chrome w/o typing the address in the address bar etc.etc.etc.. We don't need a keyboard, mouse or monitor, just a tower. Do I need a quad core? Should I choose an Intel over an AMD? If Intel, would an i3 suffice or would an i5 better 'future-proof' us? I bought a 1TB External HD because it was black friday cheap. Should I just get a 1TB Comp and return the EHD?
We will be using it for some online College classes using PowerPoint etc., email, watching youtube, internet browsing, burn some CD's, NO gaming and if I could get an HDMI port in the price range would connect it to our smart TV. I've been leaning more towards refurbished comps from BestBuy because of newer systems at a cheaper price and the ability to get extended warranties for very little money. I would rather have a Windows 7 OS Comp because I've heard it's more like XP, no one likes 8 and we could upgrade to 10 if/after we get accustomed to the 7. The ones I've looked at are

I apologize for all the questions and the super long post but as you can see we're basically computer illiterate concerning systems and knew if anyone could help me that this community could. Maybe one day I'll know half of what most of you here have forgotten about computers and can just build my own. Doubt it, but one can always hope. Thanks for any and all help!
