My daughter is having a crashing problem with her game so I'm trying to help her out. She is so frustrated bless her heart.. She just did a game update, *sounds familiar huh?* and now she gets like an hour of game play and it crashes.

Any others players, any advice gladly appreciated!

There was a recent patch that has proved problematic for some players, but that was mainly about staying connected to the server.
It was the one that featured the opening of additional ports for use by the game, tell your daughter to check out the technical support forums theres always tonnes of people having issues, and unlike EA the techs actually help people, plus there are tonnes of nerds that will help you out too.

If its internet connection/game connection issues shes having, (Disconnecting and lag) then you need to try making sure that wow is only using a certain port, since the other ones it tries to use don't work very well, at least that's what me and my husband found. It's called changing the port forwarding on the router so that a certain port is used first when opening wow, you need 3724 and 6112, and 6881-6999 to be open and accessible to run wow stable.

However if its crashing to desktop/blue screening (as opposed to Disconnecting to the character or login screens) I wouldn't think it wouldn't be a patch issue.
Make sure she removes any and all addons she has, they don't work after a patch and need to updated, removed or replaced by something created for that patch.
Try turning all graphical settings down, some patches include changes to textures and effects that some lesser graphics cards fail to be able to handle, causes freezes and crashes.

Thanks Pk! I will pass this along to her! She has been miserable about this and since I don't play I've been little to no help with it. I gave her all the Sims game problems kind of things to check out. I think she did state that she just did a patch and thats when she started having the problems.

She said her game 'freezes' after about an hour of game play. I will let you know if any of this helped. Really do appreciate this advice!
