I get "IE Cannot display webpage" trying to sign into my bank with IE8 and 9

Question

On my 64 bit Win 7 Ultimate, 2 year old PC, 3 days ago, I started getting a "Internet Explorer cannot display the webpage" message using IE 8.  I have cleared all the history and reset several times. I have reset all the network.  I have restarted
IE and the PC. I upgraded to IE 9 but the problem is the same.  From this PC i can connect with FireFox.  I can connect from my Vista Pro PC running IE 9 and from another Win 7 Ultimate, X64, PC with IE 8.
The process is to open WWW.BECU.org and provide the user id and password.  When I login, IE takes longer than usual to confirm thru
https://becu.org.../login.aspx and fails with the ...cannot display webpage.  After I clear and reset, the logon will take me to a page because the cookie is gone so I have to answer a security
quistion.  When I respond the question I get the same ... cannot display the webpage message.  If I run diagnostics no problems are found.
With IE 8 I ran bothe 64 bit and 32 bit versions with the same results.  I spent almost an hour with the bank (BECU) teck person and concluded that I have to use FireFox.
Obviously I reset something and we can't find it!  Can you help, please...

Hi,
Again the general troubleshooting strategy is to compare the settings on the two machines
Tools>Internet Options>Privacy tab. You should be using the 'default' Medium setting. Click the 'Sites' button ... you should allow cookies on the becu sites.
after checking the above settings, try opening the site in InPrivate Mode (tools>InPrivate browsing). If that works then one of your IE Addons is probably the cause (the google toolbar's Form Filler feature or another form filler Addon.)
IE has built in autocomplete for filling forms on web pages but usually banks don't allow autocomplete on login forms... Do you have to type in your credentials each time, on both machines or is your Account details already filled in when you access their
login page..... re-enter your correct details if they are already populated when you access the login page.
If that does not work then the only difference appears to be the missing MS12-006 update... You view your Windows Update history from Start>Control Panel>Programs and Features>Installed Updates. If you have'nt installed the update it should be still
listed in the Windows Update dialog (perhaps unless you use that machine to access your company's VPN, or the machine in question has at one stage been connected to a company network)
Thats about it... I cannot think of any other reasons....
You may consider abandoning using that machine for your Bank account access and secure the machine that does work by ensuring that only you have access to the machine and it is using the Ethernet connection (not wireless). Use separate windows user accounts
for yourself and your wife/partner. I keep my passwords in a small book that is locked away in a drawer and I change them every so often. Don't share access with your kids.... they are probably more computer savey than you. (sorry... its sad but you never
know).
