My computer starts up normal and it works perfectly for around 15 minutes. After that when I try to open a folder of a program it doesn't work. I click the folder and the mouse changes to the mouse and hourglass picture but nothing happens after that. Sometimes I get that error sound but no message pops up. Then the title on the title bar of my applications goes blank and I no longer can click the menu that says file, edit, view, etc. It highlights it but it won't let me click it. I also cannot right click anymore and when I try to reset my computer, it highlights it but I can't click that either. I also can't open the task manager when it happens nor can I type in my address bar or open a new tab for my browser.. I tried running a virus scan but it catch anything so I have no idea what I can do. I've tried system restore but that didn't fix it. I was considering reformatting my comuter but I still have lots of things that I need but can no longer get a hold of so reformatting is not an option. I"M DESPERATE FOR A SOLUTION> If anyone can help me what the problem is and how to fix it I would really appreciate it. Thanks!
