Laptop shutting off while playing WoW

[Wunderweezle]

My laptop runs games just fine. However, when I go to play WoW, I can load it up, and it will play just fine for a random amount of time, almost like RNG from any game you can think of. It's only ran for 5 minutes, 30 minutes, 40ish minutes, and 15 minutes before just shutting down. It's a full on shutdown and it just turns off. There's no 'The Windows system sensed a problem and is shutting down.' And when I turn my laptop back on, it doesn't give me the 'Windows has just recovered from an unexpected shutdown.' I've tried messing with in-game settings so my CPU and GPU don't have to work as hard (keep in mind I play Diablo 3 on relatively high settings, even in dense environments. AKA, more hardware demanding than WoW, and thus hotter), I've updated my drivers to the latest update there is, I've even just updated Java just because I couldn't think of anything else lol. Even my WiFi card I chose to update. I've done anything and everything I can possibly think of, and I can't think of why it shuts down unexpectedly while playing WoW. Is there a possibility of downloading something incorrectly during the downloading/installing process? It seems very unlikely since I've downloaded it quite a few times before from the same source (battle.net, Blizzard's well-known home website) and it worked perfectly fine, on this same laptop. I am completely out of ideas, and I would appreciate any and all help and/or suggestions. Even just talking about it to see if there's anything I can do. Again, anything will be appreciated. Thanks for reading this long post, and hopefully posting a response.

Well, I don't use my NVIDIA Graphics Card, because ASUS messed up something when I had to send it back in to fix my WiFi card. I got it back, and my laptop couldn't pick up my NVIDIA GPU, and I didn't have money to send it back and get that repaired, so I just stuck with my Intel HD Graphics 3000. I just updated the drivers for it last night before I posted directly from the Intel website. Intel has this in-site program that reads the components of your PC and says whether there are new drivers available for the spec or not. And I just finished my WoW install yesterday, and it's a big download, so I haven't had time to try a fresh install yet lol. But I don't understand why it would download differently this time when it was fine for the rest.
