Is it my computer or the site?

I wanted to view a profile of a member to endorse him but when I click on the member all I get is a blank screen, totally white. This happens with other things like when someone has tagged me on a thread they posted as well. They are members who have not blocked me. My profile won't even come up! Any suggestions?

Update, I switched browsers from Firefox to Chrome and it came up. Don't know what the deal is but was annoying.
