All the things I've noticed not working were: Windows Side Bar (freezes up on boot) Windows Task Manager (shows up in the applications bar on the lower right, cannot access it) Pidgin (also shows up, but only as an empty space) When I boot my computer, sometimes my fingerprint software/password interface lock up- this being roughly 70% of the time. Google Chrome is the only browser I have that's working. I attempted to download hijackthis only to discover apparently anything to do with downloads also causes a freeze/crash on the program. The other thing I've noticed is over prolonged use my laptop is hotter than it has ever been. I am using a Dell Studio 1535 series, if that helps. What steps should I undertake from here?
