You don't mention what you've tried to do to fix the problem. For instance, have you downloaded the latest Nvidia driver for your GPU?
It doesn't sound like a hardware problem Have you tried running the game without mods? The very first thing you should suspect in a situation like this is that you have a mod that is causing problems.
If errors are occurring during play that prevent things like the info boxes from working correctly, then the game should be generating error reports. Look in your files (if you aren't using Steam, I'm not sure where your game files are) for error logs. If you find error reports, open them and look at them or copy/paste the info into this thread.
Also, World of Warships almost certainly has support available on their website if we fail to fix your problem here, or you may want to go ahead and contact them.
