Help

So whenever I go on chrome my computer gives me the blue screen and restarts. I uninstalled chrome, using ie, i tried downloading chromeplus. Click on a link, all these redirections so i had to copy and past the url. It downloaded and when it went to install, big surprise, blue screen again. I know people are gonna say "reinstall os". Avg recently has somehow had the fuckin firewall off, but it still catches shit when I get redirected because of this virus shit. What should I do? Dont wanna reinstall os because then i gotta torrent and all that shit for windows 7.
