I'm having this problem with Firefox, I can't load up pages, watch videos, save images or anything else properly. It always hangs for some seconds, sometimes getting the "not responding" added to the window name. I already tried everything I found on the support pages: cleared cookies, tried safe mode, tried with a new profile, disabled plugins, reinstalled Firefox, disabled hardware acceleration, resetted settings, cleared sessionrestore, scanned for viruses, checked the firewall, cleared download list, checked the hard disk for errors (got none), and other stuff I forgot. Results? None. It's all the same. If I try using Internet Explorer, on the other hand, I get no hangs at all, so I don't think it's a hardware problem. What else is left for me to try? Please, these hangs are getting on my nerves. (and sorry for the troubleshooting information being in Portuguese, I don't know how to change it to english without translating it myself)
