A:AnswerI would think this PC can run Skyrim. I'm using both Sims 3 and 4. Many people have problems running 3 as it is very graphics memory intense. I run 3 with all packs in use, mods, and a lot of custom content. It works fast! I was especially impressed with download speeds.
A:AnswerWhat does it show you're not connected to? It sounds like a connectivity issue (for example with your WiFi router or internet service). Unfortunately this is not enough information for us to adequately troubleshoot. If it is in fact the computer and not your connection or ISP, please contact HP Tech Support directly for help at https://www.support.hp.com/us-en
