I am on an older computer, older CPU, older processor, etc., but it's run perfectly for about 10 years now. Suddenly, it shut itself down and started up again. Now, my computer is incapable of starting basic programs (all of which on Steam) that ran perfectly before. The computer will display the hourglass and the app shadow, like it's soon going to open, for about 1/5 of a second, then it reverts back to nothing. I waited 40 minutes -- not seconds, forty full MINUTES -- for Fallout Shelter (one of the most basic Steam games in existence) to load before I gave up. My sister's friend decided to hit a bunch of buttons, and I'm pretty sure that it screwed SOME stuff up, but it seems unlike such a trusty computer to suddenly give up on me. I have, like, 40 anti-virus, anti-malware, etc. apps on this computer, so I doubt anything will get through all of the sieves undetected. Also, the computer-saur that I'm using is an HP Pavilion Elite HPE-400f PC with a single-core, 3.0 GHz processor, and a relatively new graphics card. So, give it to me straight, doc; is she gonna make it? What can I do?
