Certain trusted websites don't work on Windows 7

A particular trusted website which normally works for me on Windows XP & Mac doesn't work on my new Dell Inspiron laptop running Windows 7. I tried both IE 8 as well as Firefox 3.5.6/3.5.7.
When i log into this page, it first shows up as empty & then loads up when i manually refresh the page.
Strangely, it works on another HP laptop running Windows 7. I compared both these laptops & everything seems similar, not sure what else to look for.
Please help.

I the below options & still didn't help:
Since this was a optimized Dell laptop i bought at best buy, i did a factory restore.
Turned off Firewall. Not sure what you mean by A/V?
Added this site to the trusted site list.
All entries in the host file are commented out.
Tried on Firefox as well as Chrome.

Yes, i did run it once. I even uninstalled Norton Internet Security as somebody had suggested this in some forums.

i do not know if it is a win 7 problem or an isp problem. i get the same thing when i try to go to pages that i had no trouble with in vista. i'll get a blank page and have to hit refresh, or i will get a timeout and have to hit try again. at this point i finally get my page. i have tweaked the timeout for firefox and ie and still have this happen. some have suggested that it is the ivp6 interfering with ivp4.

I do not understand why it was suggested Norton would cause this.

It will give a reccomendations if the site is safe or not based on its reputation, but still should not block anything. Only a warning in the browser.

Unless the site in question is a known threat, and deemed dangerous, it will:
But as any other security suite that has similar capabilities, it will always give a reason as to why it stopped the page from loading and wait for user input to continue on or accept the recommended action.

If Norton is not alerting you to a threat or saying anything, theres quite likely another issue. As it doesnt see a problem worth mentioning.
