Hi, I have an HP Pavilion laptop with Windows 8. A couple days ago, I experienced very strange things happening to my laptop, and I fear I will have to buy a new one if I don't figure out how to fix it. I got this laptop used from Best Buy about 7 months ago. When I got it, it was full of viruses, and probably the slowest laptop I've ever had to deal with. But after cleaning it up, it works just fine. Now just a couple night ago, before I went to sleep, it had to update before shutting down. So it did just that. The next morning, my desktop and other icons would disappear and reappear, and would exit out of any screen I was in. This would happen every few seconds, making the laptop pretty much unusable. But with the help of the trusty internet, I was able to put my laptop into safe mode, and put the laptop back to a restore point from a month ago. After that, pretty much everything went back to normal. But now, every time I log on, along with every hour or so, I get a message that says I need to activate Windows in my PC settings. So I try to do it, but it just takes me back to the start menu every time. Also, all of my apps have small exes in the bottom right corner, I'm not sure if that would help my case. So basically, it won't let me activate Windows. If that isn't enough, I've seen the desktop flash a couple of times like it used to, but not NEARLY as often. Along with that, there's now small white text at the bottom right corner of my desktop that reads "Windows 8.1 - Build 9600." Also, when I try to do an automatic Windows update, an error occurs. That's a bit of a problem too. Along with this all being very strange, I fear that my laptop is about to die on me. Do you guys think a factory restore can solve the problem? Any thoughts at all would be very appreciated. Thank you!
