I'm not sure how to describe this problem. It is like I don't have internet but at the same time I do. The problem happened randomly, I left my computer to watch a movie and came back to my machine and the issue occured. I normally use firefox as my web browser and when I loaded it up I got the screen that it couldn't connect. The one you see when you have no connection to the internet. I assumed my modem hung up and promptly rebooted it. I tend to leave my machine running for weeks without powering down. This did not fix the issue. I checked my laptop and it had no problems connecting with the ethernet or the wifi so I know its not the modem. Randomly i loaded up IE (accidentally) while looking through the trouble shooter and it worked! Here is where it gets "odd". No other program I have can connect to the internet. I can't update my spybot or antivirus programs. When they try to connect to their repsective servers it gives me the same error that you would get if you had no connection. I am currently on said machine using the only program that connects to the internet, IE. I just recently installed Windows 7 Home Premium. I had XP Pro. I did not upgrade. I formatted and did a clean install yesterday. I had no issues at all until this evening. The OS runs like a dream and overall I'm pretty impressed with the "fixes". I really don't know what could cause this problem. Any ideas? Here is my system info: Processor: Intel Core2 CPU 6400 @ 2.13GHz with 2GB Ram OS: Windows 7 64-bit Dell Dimension E520 Let me know if you need more info I'll be more than happy to provide.
