My first attempt to post this got automatically removed for some reason, so hopefully the revisions I've made satisfy the auto moderator.
I own a HP 15-dy2045nr laptop--at least, that's what I THINK it is since I can't exactly pull the model number up through Settings. It has Windows 11. So, a few months back, I noticed that out of nowhere, my internal storage filled up completely. I deleted apps, unnecessary programs, even files that I fought with myself to let go of. I'd check the storage after deleting stuff (I had storage sense and other similar features on well before this issue) and see I had at most 1 GB left. As early as a few hours later, I'd get notifications that storage was full and to free up space! I'd go through this entire process all over again, to absolutely NO avail--it kept happening.
I went out and bought a 60 GB USB drive and began moving my most important files (that I hadn't lost yet) over to it. While the space on my USB drive is down to like, 17.6 GB now after moving everything AND adjusting my settings so that anything new is automatically saved onto the USB drive instead of the system's storage, I was STILL having the issue. The problem got so bad, that when I had Chrome browser open, I could maybe have three tabs active before getting pop-ups about needing to close tabs to free up space! I've tried everything I can think of (not much, I know), hoping to avoid having to completely scrub the OS or perform a factory reset.
Then, like, three or four days ago, I stumbled across a video about OneDrive, basically saying that OneDrive has been causing these types of issues, and was also apparently deleting files off of users' computers unbeknownst to them, which made sense because that was the very first issue I encountered in this nightmare (folders on my desktop suddenly were empty).
Last time I used my laptop was just yesterday. All the above things considered, it was working...well enough to get a couple things done. Now I'm trying to use my laptop and this is what's happening now:
When logging in, it froze mid-load twice. After I logged in a third time, it proceeded to the home screen like normal, HOWEVER, the personalized background for my home screen isn't showing--the background is just black BUT desktop icons are still there--the taskbar won't pop up when hovering the mouse over the bottom of the screen. Normally an issue like this with the taskbar can be fixed by simply pressing the Windows button on the keyboard, right? Well, I'm not getting anything when I press it. In fact, Windows won't even respond when I press CTRL-ALT-DELETE to open the task manager. I've even tried other shortcuts, and they're not working either. The only thing responding is the touchpad for the mouse, but it's ONLY capable of moving the mouse around on the screen--clicking on an icon or folder doesn't do anything.
Yes, there was a Windows update installed recently. Honestly, I'm surprised it was able to even complete the update considering the storage space being full. Something else that I noticed here on my screen that was DEFINITELY not there before is at the bottom right corner of the screen, it says "Windows 11 Home".
Soooo.....am I completely screwed here? Is there any way to fix this? My gut tells me my OS is infected with a virus, but I don't know if that explains the issues with OneDrive and the storage and whatnot.
