Why do I keep getting a blank screen going to a cnet page? Unless keep clearing cache. Everywhere else works.?

Just a blank screen, unless I clear cache, cookies, etc. Then I can read and even log in and comment. The comment appears, but then blank, and I have to clear everything again. Never had anything like this. Don't tell me to send them a message: how can I read a reply in my account. Anyone know what gives?
