Problem with the keyboard (didn't know where else to ask)

Hello! Im not sure where to ask, but there's something off with my keyboard (usb), which started about 30 minutes ago. I Tried restarting my pc and unplugging the keyboard twice, but it never worked. Every time I press a key, it'll be numbers or symbols. The back space puts in "-9" when I press it once, but if I press and hold, it keeps spamming the dash. The shift button does the @ symbol and the space bar does symbols before immediately entering. I'm now stuck on the password page, and can't do anything. When I press shift and another letter, it does random symbols and immediately enters. Before i restarted my pc, I couldnt enter anything into google. When i would type, it did the same as i descrived, but when i entered it, it deleted. I could only copy and paste things into the search bar. I've tried what I know, and I'm not sure what else to do. Help would be appreciated!!!
