Can't Access Firefox IE (regular Mode) / Can In IE 64bit Only

I didn't turn my laptop off, which is normal when I'm downloading stuff, I didnt do any updating lately. When I woke up this morning, my computer can't access the internet. I can't log onto Skype, can't access web using IE, Firefox( my regular one used the most), a chines one I sometime use for chinese websites. I have another 2 computers in the house and they both are fine, can access all programs as usual. After using restore point, I reset all firewall( remove all firewall), removed all blocking programs, redownloaded IE and Firefox on another computer and re-install on the one with problem, nothing.I thought it was network issue. even though it shows 65% connectivity, I tried to reset the router, the whole works, nothing. other 2 computers still fine. I put in my d-link use wireless thing, have connection, websites still cannot be accessed.

I finally tried IE 64 bit, which worked. So I thought, ok, maybe a clitch. i tried other programs again, nothing. For some strange reason, only ie 64 can access the net on this computer now, which I HATE.There is no firewalls on router or otherwise. ISP is not limiting, as other computers are fine.
