Create a new windows account and log into that.
If the problem follows it's something on the PC.
-> Before that you need to be sure there is no malware. I use Grif's advice on that.

And next time, don't uninstall but reset the browser. Here's how for firefox.

If you do find pests, increase your protection. Here I added WOT (web of trust) and Adblock+ to firefox.
Hello everyone, I'm having a real tough time trying to figure out what is going wrong with my computer:
In as short as a few minutes to as long as a few hours, my computer will completely freeze (keyboard takes no input, mouse is stuck in last position). The only way to resume usage is to reboot after holding down the power button.
The only common thread through all the freezes *seems* to be the active use of a web browser (Chrome/Firefox/Explorer). The freezes only seem to occur when the active window is one of the web browsers (and possibly only when the browser is in 'full screen mode', still testing that) what that points to, I have no idea...
I did a uninstall and then re-install of all browsers with the most current versions, but after a few hours of Chrome / Explorer, I got another freeze.
Any ideas as to what is going on is greatly appreciated, thank you for reading.
