I'm Having A Problem Logging On To A Website. Any Suggestions?

I bought a new computer a couple of weeks ago (it's an HP that was on sale, so don't laugh) and for some reason when I go to my bank's website I can get to the homepage and put in my username, but it won't go to the next page where I put in my password. All it gives me is a blank page. I have no idea what the problem is, so I thought I'd ask the experts if you have any suggestions.

I'm leaving for dinner in a couple of minutes so if I don't reply right away, I'll try to get back to you as soon as possible. Thanks for your help!
