Okay, so my PC's had a few problems this morning. First, I heard an odd noise when I started it up (didn't sound like a hard drive or power supply at all, it sounded more like one of the fans; I'm still not sure it's a fan, I can't be sure what it is yet. I just think I can safely rule out the power supply, and most fortunately, the hard drive as well) then later on it froze on me entirely. Had to give it a hard reset.
Gonna have to see if these issues persist and look into it to find out what it might be and if it's anything serious. I can't do that right now nor do I have the time to write-up replies to earlier posts. I'm gonna have to go about my day normally and look into it after getting some studying done. But if I'm completely absent for a while later and for at least a few days to come afterwards, then chances are, it's because my of PC's issue(s). Just figured I'd give a warning.
