Starting last night, my laptop has been freezing within 10 secconds of getting on the internet and sometimes just randomly. It will start acting slow, windows explorer not responding, then everything freezes, even the mouse. I have run avg free and nothing came up, so now I am downloading a program to get rid of a notorious hijack and a reg cleaner.
If this doesn't work, then I may have to re-install windows (grrr) so any help would be appreciated. And I dont have an Nvidia card, so it isn't that bug.

Btw, typing from an ancient computer that shuts down randomly because the idiot who assembled it (custom) didn't connect the fan and overclocked it mad high, burning up the processor and crap when I tried to play crisis... but that is another story.
