Windows 7 - Pages won't load without several refreshes

Hi Everybody,
I'm having a strange problem that I have never seen or heard of. Every time I try to do anything in windows 7 that requires an internet connection, it gives me a "Page cannot be displayed" or "Page not found" message. The only way I can get some pages to load is to refresh them several times, after wich they will finally load. It is not just a problem in IE8, as Chrome, and firefox do the same thing. Windows will not update anymore as it cannot get a connection, and I cannot purchase items from steam or itunes because they give me a "cannot find a secure connection" error. I recently reformatted and the problem still persists. Other PCs on my network do not have the same problem. I recently moved all of my components to a new chasis, and am wondering if the ethernet port or controller could have been damaged. If anybody could shed some light on this problem it would be greatly appreciated, as my PC has become almost unusable.

Hi Noah,

Have you tried running Network Diagnostics when this issue occurs and can you upload the report it saves?

Thanks for the reply,
I have tried it several times but it reports everything as normal. When the problem first arose however, IE8 would run a repair wizard to try to fix the problem, but it kept crashing and shutting down my browser. I had to restart several times before IE stopped running the wizard.

click start, in the start search box, type cmd and press Ctrl+Shift+Enter. in the command prompt, type the following commands:
ipconfig /flushdns
ipconfig /release
ipconfig /renew
Note: press enter after each command.
delete all cookies and temp files and see if its making any difference.

If the above doesn't help: Give Wireshark (Wireshark: Go deep.) a try. Just start it, start sniffing & try do open your webpage, then post the results here.

Hey

Try this: In IE goto tools>internet options>connections>lan> UNcheck auto detect.
Reboot computer and cable modem, and router. If that doesn't work we need to start examining your device manager, and event viewer

2 things to note:

At first glance, that to me indicates some sort of massive OS structure failure and / or massive viral / malware infection. however,
...indicates a troublesome driver for your NIC and / or a major IRQ conflict on your system or bad hardware.

Get your HW checked (a *nix live CD / DVD is a good way to check it) - if all works well, then it is either your OS installation, or else something somewhere infecting you.

If you need to reinstall *again* make sure you use a completely different to rule out (and help prevent future) infection.

After using the "ipconfig /flushdns" command, browser pages seem to be loading fine. The main problem now is updating windows. I had to activate windows over the phone because the activation wizard could not get a connection, but windows update still can't connect.

To fix windows update, what's the error that you get while updating?
If you are facing severe trouble with windows, you can do a repair install to fix many issues.
