URGENT! Help Needed!

The thing is, I bought my PC with no Windows install disc.
This is why I haven't just wiped my PC.
I was logged out of google though, which is a little worrying, and looking at it more, I notice some places around the PC say the contents of the folders/items have been modified at the time.
I know PCs do that when something happens, but Malwarebytes has said "nope" to me for the 10 times I've been anxiously searching through my PC. I do have the most secure settings on Tor, and as I said, it is up to date.
If I remember correctly, this has happened previously while on Tor, and with other programs as well, so this eases my anxiety a little.
But why would explorer.exe crash?
From what I read, it's basically the whole UI, like the color of the edges on programs and the taskbar.
