Hi, lately I found my computer to be freezing and stop working. Although the mouse still moves during these time intervals I can't connect to the internet and things won't open or take awhile. It has times of running just fine as well. But these occurrences are happening way too often now, when they used to never. I have a very capable computer and I have no idea what the problem could be. I tried defragging my harddrive, system cleanup, uninstalling programs. I have about 75 GB free of 250GB on my hard drive. Any resolutions you could come up with for me? I'm out of ideas and would really like them to stop. I feel it could be a simple driver issue but I'm not a computer doctor. Thanks for your time!
