No, it's not your pc. If you encounter a white screen, refreshing usually does the trick. It's a sporadic error so is tricky to pin down, may take a day or so. Just to let you know!
Hasn't happened to me today, yet. I've only been on for a little bit though. When it happens, I just click the back button and try the link again; works fine for me.
