I feel real dumb even posting this, like my grandma asking for tech support help, but I haven't been able to fix this myself, so fuck it.
I'm on a fresh Win7 install, just finished getting everything back the way I like it and installing and my apps and settings and shit a few weeks ago. My PC is left on 24/7. Lately when I come back to it after waking up, it's frozen up. Mouse will move, but you can't click on anything or alt-tab or anything. Ctrl-alt-del + task manger usually unfreezes it, but this can take anywhere from 30 seconds to a minute or two. I checked for malware and rootkits and such, came up empty. Anyone got any ideas? I would really prefer not to reformat again, I just don't have the time right now to get everything back up and running right.
