Have a Dell Inspiron Desktop that came with Windows 7, but I upgraded to 10 when it was offered. I'm not sure how old it us, but I'll guess 6-7 years. I usually leave the computer on and let it go to sleep, unless I'll be away from it for a while then I turn it off. Yesterday I woke up to a black screen. Initially thought it was the monitor as the computer seemed to be making noise like it was working, maybe downloading updates or something. Waited a couple of hours but still black. I shut off the power, unplugged and re plugged everything, restarted, got the "dell" logo on the monitor, then it went black again, but it alternated between dark black and a lighter black and I heard the same noises from the cpu itself like it was doing something. Now wondering if updates were the culprit, I thought I'd give it another day to see if things worked out on its own after it finished up. Today, the screen was blue, and had a message that said something to the effect that it looks like windows didn't load correctly, and offered the troubleshoot menu, which I went to. I just need some advice on the best order to proceed. I don't want to lose any files. I already went to the "advanced options" and tried the "startup repair", but that didn't work. Is it better to use system restore in the advanced options, or "reset this PC" (keeping my files) or something else entirely?
Only other info I can tell you that may be of importance is that recently I'd been getting some popups (some noisy fake thing telling me I have a virus and I need to call a phone number to fix it - I just close out via the task manager to get rid of it). I use SuperAntispyware on a pretty regular basis. I also have Avira, but recently noticed that I couldn't get it to open anymore, so I uninstalled and reinstalled that and it was fine. Ran a full scan after. There was one thing that was quarantined and one "hidden object", but I cannot remember the specifics now. .
Any advice appreciated.
