For a few reasons:
1) Freezing a lot. Now this is happening in Firefox, so I'm not sure if it's the program or what. It seems to follow pretty much the same pattern. Will happen within the first half hour of me turning my computer on. Usually, when I go to a new webpage, the tab will say "connecting"', then it will go into not responding mode. This will last for 5-10 minutes. At first I can go to other programs, but then the whole thing seems to freeze up. Then it will go back to normal, then freeze again for another couple of minutes. Then back to normal till I turn the computer on again.
2) Audio has been weird lately. Random crackles. And some weird digital crackling kind of thing sometimes.
3) Video card is maybe fucking up, because some of my text looks like this now:
Also seems like it's maybe been running a little hotter than usual/using the fan more? Whenever I do anything intensive, like gaming, I use a cooling pad. So dunno.
