Hello. This is my first post ever so i'll try to keep this pretty basic.I just received a 4 year old laptop. Its not great but it was originally Windows 7 and i have now upgraded it to 8.1. it has 2.23 gigahertz dual core processor and 4 gigs or ram. Its decently fast. I have already wiped all malicious programs from the laptop I.E. virus ect. But no games will launch. I have multiple copies of games that i know work fine but still everything fails to launch or produce a form of error code. Some games simply do not respond when i right click the application and attempt to open. And other games will just pop up an unrelatable error code. I have spent 48 hours trying to fix this myself. I even went to the length of going into command prompy and running the sfc /send Command line. Not that i know what that is or does but it wasnt detrimental but also didnt work. Please respond.
