So, I'm going to do the best I can to explain this, but it's a little tough to make sense of.
Twoish weeks ago, I was having issues at boot. My laptop would not boot from sleep or from restart randomly until it stopped booting altogether. It started going through startup to the windows logo, the spinning thing, and then all lights would stop except the backlight was on a little on a black screen. Nothing would make the machine do anything. So, the only way to get away was to hold power for 5+ seconds, then I would restart it, same thing. So, I hammered F8 to try to boot in safemode, but I don't think I was ever able to get that to work. It would go to the options screen, but safemode would not boot. It wouldn't go to a previous savepoint either. Startup repair from that screen was of no help. Ultimately, I made the absurdly stupid decision of doing a system refresh without fully realizing what that meant.
Cue having to rebuild half my computer and say goodbye to half my files.
Anyway, after the refresh, pretty much immediately, more weird things began happening. Most times upon waking from sleep or restarting, two-finger-scroll on my touchpad will not work immediately and then additionally, usually within a few minutes of waking/restarting, the command prompt box pops up, sometimes it goes away quickly but sometimes it blinks for a while. Eventually, it writes some prompt itself and disappears way more quickly than I can read it. Then, I pretty much run normally until I sleep/restart. So far, running AVG, MalwareBytes, and CCleaner have yielded what they did and the problem persists.
Today, the system installed updates and freaked out and the black screen boot happened again. It would not allow me to boot into safe mode. This persisted for about 13 hard resets until, for no reason that I can tell, the system decided to start up, finish installing the updates, and allow me to log on and write this. Once started, the command prompt box thing happened, but I had no reason to scroll immediately so I don't know about that issue.
My touchpad drivers are up to date as of the refresh.
Any assistance deciphering these oddities is highly appreciated. Thank you.
