I have recently started having an issue with my Vista desktop. I've had it for almost 4(?) years and have had very few issues until now. Within the past couple days, my computer has decided to start freezing shortly after boot. I log in, everything seems fine. I let it set for a few minutes to make sure all the services have started. Then, I try to do something and it freezes. Something as simple as trying to get Google Chrome to open, or even Task Manager via the right-click menu on the Start bar. It doesn't completely freeze, though. I am still able to move my mouse around. It stays frozen for 5-15 minutes then unfreezes on its own and goes through all the things I told it to do. However, once I try to do something else, it'll freeze again. I have not installed anything recently, nor updated any of my drivers recently. I thought it my processor was overheating due to dust, so I blew it out. Didn't help. When it freezes, the processor light on the tower is solid. I am a Network Technician Assistant at a school district, so I know my computers fairly well. I've never had this problem, though. I was able to get Task Manager to open and it only shows my CPU usage to be 1-7%. I am completely out of ideas. Care to help a fellow out? If you need some more info, just ask.
EDIT: I forgot to mention that I have booted in Safe Mode and it worked perfectly fine. I ran a full virus scan which found nothing. I also ran a Boot-time Scan which also found nothing.
EDIT2: I was able to get Task Manager to stay open during one of the freezes. It's actively monitoring the CPU and Memory usage. CPU Usage is 1-3% and Physical Memory is 34%.
