@Summoner, your issue sounds different... Might be the same issue depending on the level of data corruption (if that is indeed what is happening). Our peak server times are around 2pm PST. If you try outside of peak times, either late night or early morning PST, and it works better, let me know in case it's load. If it's your browser... I'm not sure what to do there. Try some of the suggestions from the thread linked above.
-Disable all your browser addons to see if one of them is the culprit.
-Try a different browser to see if something is wrong with that specific browser.
-Check your network card drivers to see if you are using a Realtek card and if so, try some different drivers.
-Try another computer on the same network to see if it's a hardware issue in your computer.
-Try your computer on another network to see if it's a problem with you network setup.
Those should help you isolate the problem.
