I installed the 10.3.8 update about a week ago and since then I've experienced almost 10 different instances of freezing, four in the past 24 hours. It seems to somehow be associated with being on the Internet, but randomly my computer will just completely freeze up. The mouse will still respond, but when I try to move it it'll stutter. Other than that, the entire interface is locked up and won't respond to any keyboard commands, including Force Quit. The only way I can regain use of my computer is to hold down the power button and restart. Does anyone else have this problem or know a remedy to it? I've considered completely cleaning out and reinstalling everything on my computer, including the OS (the good 'ol clean install trick that used to always work on my Dell), or is there another way to go about fixing this problem? Thanks for anyone's help.
