Windows 7: Some webpages simply never work on my desktop unless I use proxy. Why?

Some webpages simply never work on my desktop unless I use proxy. Why?

I've been having this issue for as long as I can remember. Certain sites simply never load on my desktop. My Firefox and my IE would indicate that the page is down by returning the following error:

Unable to connect

Firefox can't establish a connection to the server at

The site could be temporarily unavailable or too busy. Try again in a few
If you are unable to load any pages, check your computer's network
If your computer or network is protected by a firewall or proxy, make sure
that Firefox is permitted to access the Web.

I've got a handful of sites that give this error. I've tried formatting and it doesn't help. Theses same sites work FINE from work, from collage, and from my cellphone (Android 2.3) but NOT my damn desktop.

At first I thought maybe Comcast was blocking them but then I realized that I CAN view them on my Android phone, using Dolphin Browser, or any Android browser for that matter when connected to my Wi-fi which obviously, is the Comcast/Xfinity.

I Google'ed public proxy's and found one called hidemyass which is a web based proxy. I can toss the websites in question into the hidemyass and they work. I've been using the proxy's as a work around but frankly they are SLOW and very inconvenient in general.

I'm lost... Thoughts?

Operating system is Windows 7 Ultimate SP1, 64-bit with all the latest updates.

You say you tried formatting. Specifically what did you mean by that? It's possible you have listings in your Hosts file preventing access to those sites. Or have a security program blocking access. Try booting to safe mode with networking, and see if you can access those sites then. Only as an experiment, as your AV software won't be active. If you can access in safe mode, next step would be to try a clean boot to see if a program is interfering.

Formatting? What type?

Have you tried clearing the cookies and the cache in each browser?

Connection problem. Webpages don't load, downloads still work.

Bluetooth has Simply Disappeared
OK, this problem has me perplexed. Bluetooth seems to have completely vanished from my computer. I've reinstalled the driver to no effect. The only thing I can think of is that I usually kept the adapter disabled, and that I deleted the HP program which toggled that adapter on and off. Other than...
