My Windows 7 PC these days acting very weird:
Examples: It can not open Bing.com, alexa.com, msdn.Microsoft.com (blank page or page can not be found); It can open zdnet.com but lost all CSS layouts and pictures; It can open stackoverflow and Google no problem;
I tried all three browsers (Internet Explorer8, Chrome, Firefox 3.6) same thing.
I didn't change anything on this PC in days. This PC does have Anti-Virus installed and updated. I'm also pretty sure it's not a network problem, because my other laptops are just fine at the same time.
The only thing I can think of is it might be some auto-update stuff underneath happened without my knowledge, but I have no idea where to troubleshoot?
Please shed some lights for me?
