super slow performance for all browsers

Posted on 2011-09-03
Last Modified: 2012-05-12
Approx. 24 hrs. ago my three browsers became extremely slow on both my office and home networks - no other machine on either network behaves similarly. Recent developement - on many sites the page only partially loads and refresh fails to progress past the initial partial load. At home, where none is required, proxy settings set to No Proxy for all browsers, including IE. Another oddity - many links now require double-click to activate. I have disabled all add-ons. Trend Micro and Malwarebytes scans come back clean. Machine is ASUS G74SX, i7, 8GB RAM, Windows 7 Ultimate, SP1.

Here's another symptom - when I returned to my office network today, the problem went away. However when I got home, desperately slow browser performance. I rebooted in safe mode with networking and browser performance was once again fine. I rebooted normally and disabled services I thought might cause the problem, but no luck. ZeevM33 suggested running the atribune ATF Cleaner but the utility is for XP and Windows 2000 only - I'm running 7 Ultimate SP1. That said, is it possible a temp file relating to networking is the cause of my problem?

Ah windows 7...
1. Open Control Panel>Internet Options>Advanced Tab>Click the Reset button.

if this was an addon / Proxy / or a specific setting , this should fix it...

2. In command prompt type the following : ipconfig /flushdns

3. check if you have any Static DNS configured on your card.
4.Check hosts file.
