Ok yesterday morning around 5:00 am my CPU fan started running really fast and was pretty loud. I got up, turned on the monitor and neither the taskbar nor RocketDock was responding, but my mouse was working. So I restarted and it took a good 3-4 minutes after my background appeared for the taskbar and all the processes to even start loading. I tried to connect to the internet and it got stuck on Opening port. then I opened Firefox and it never came up. I opened the Task Manager and it said they were all not responding. I went to processes and tried to closed down Firefox and rasphone, but they wouldn't close. I've never had that happen before. Usually when I go to Processes and close something it closes instantly, but they never shut down. RocketDock still worked and I clicked on CS3 a couple of times and it never opened, and I don't think it's process appeared. My computer wasn't running slow or anything like that. I restarted in safe mode, ran avg and went to school (my fan ran loud the whole time) . Came back, restarted, again it took 3-4 minutes after my background to appear for any processes to load. But everything ran fine after that. Avg found nothing from the scan. So my computer ran fine until 1:13 am this morning, when I was again woken up by by a loud CPU Fan. This time I checked my mouse and the light was off, so I clicked it and it and my keyboard and my monitor turned on, and I think my CPU Fan went back to normal, but the mouse and keyboard were frozen. So that's where I am. I didn't install anything before it started happening. Is my comp going into some weird sleep/hibernate mode?
oh and my fan is usually loud like that until Windows boots, then it quiets down. and I checked my cpu temp on all occasions and the temp was pretty normal each time.
tl;dr : nighttime loud cpu fan, proccesses wont close or start/computer lock up
