Mmm.. my laptop screwed up somehow

[Sindread]

So I come home from school, mom tells me she shut down the laptop, so I force shut it down to end it quickly (because shutting down on Windows is like waiting for a stone wall to talk to you). Later I notice my mouse wasn't recognized.. I plugged it in (it's wired, the red light underneath it is lit when I plug it in in any of the USB ports) all the USB ports, but none of them worked. But my mouse showed no signs of death or.. malfunction.

I try searching on the Internet and I found out a way to see if my laptop wasn't recognizing my mouse, I opened up "Device Manager" and it told me my PS/2 Compatible Genius Mouse was being recognized, but it just didn't worked no matter what I did, I rebooted my laptop, plugged it out and plugged it in, all sorts of stuff. A few minutes later, I open a game which has sounds and music on it, I can't hear it at all. I see an (X) on my sound notification thingy and I think "guess it was muted" so I put my finger on the mute button on my laptop, it didn't change.. it kept the (X) there. I hover the sound notification thingy and it says "No Audio Output device is installed" and I'm like "but it's a laptop, it comes with the Audio Output device installed", I try to fix it with the common "update the driver and it'll fix!" technique, nope it did not work. I troubleshooted and it just told me to ask an expert or search the Internet, like it usually does.

What the hell is happening here?

Your drivers are messed up. You'll have to right-click each one, go to properties, and update/reinstall each one. If there isn't an option to do so, you'll have to uninstall them, then click the 2scan for new hardware button. If it doesn't automatically install, you'll have to do it manually by either googling the drivers, or looking on your laptop manufacturer's website, if they are nice enough to put them on there for you.

Never, under any circumstance, should you force-shut down a computer, unless the system halts. When it's running perfectly fine, especially when the hard disk is running and especially if it is writing data to it, always always let it shut down properly. If you force-shut down whilst data is being written to the disk, you can corrupt it and you'll have to reformat it, or if it's a Seagate, chances are you'll physically damage it as well.

As a computer expert (who has fixed every single problem thrown at him up until now) I say:
"I AIN'T TOUCHING THAT!"
Reinstall your drivers. Like... All of them! How did you even manage to do this?
