My laptop screwed up big time.

Hello,

So I come home from somewhere, one of my friends tells me he 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 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 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.

How did this happen? I just don't get it.

Here's what the Device Manager looked like, apart from all the /!\ marks, everything else was fine, I checked all other devices and they were ok.
