My system freezes several times a day, and it did the same back in Vista before I upgraded. I've finally found that most freezes occur within a few seconds after I plug in or unplug my headphones--but not every time I plug in or remove my headphones. Most of the support forums I've visited have said that that's ridiculous, but I'm hoping someone here knows how to help. I'm terrible with computers, so if you need additional information to troubleshoot this ask for it and I'll post it. Thanks in advance.
