I was working on an assignment and I accidentally kicked the back of my desk which touched the plug behind it. The outlet where my computer is plugged in is very sensitive; if I move the plug around even a tad bit the computer tends to shut off or reset if it regains power. So my desk pretty much bumped it although it didn't really "unplug" per say. The computer didn't shut down, it just went to a black screen like I'd usually see when booting the computer where it says "press f9 to enter BIOS" (or whatever function key it is). It just sat at that screen and didn't load my login. So I just held down my power button and rebooted the computer and it is working fine. I just want to make sure I didn't potentially damage any hardware or anything. I know unplugging the PC straight up isn't good for it, but I found it strange that it sat at the black screen. Is it an issue?
