Anyway, for about a month now, my computer's been freezing up every now and then for anywhere between five seconds to a minute. Programs won't respond, I can still move my mouse, but I can't click on anything. I've tried Googling, but it looks like there's a dozen different things that can cause it, and it's all pretty random.
I opened up the Task Manager and noticed that the CPU drops to 0 during these freezes. I'm not quite sure it's a heating issue, as my system's usually around 49 degrees Celsius. I've defragged my hard drive, and it seemed to let up for a bit, before going back to how it was. Updated a ton of programs (Java, Flash, various other programs), and it, again, seemed to get better before suddenly going back to doing it just as often. Ran a virus scan, came up negative.
I bought some compressed air and sprayed into my vent, and a huge cloud of dust came out. It still kept doing it, so I'm pretty sure that's not the problem.
Anyone here know what the problem could be? I can post a DXDiag if it'll help, just say the word.
