Dell XPS 15 Crashes while playing video games

[Nalais]

I'm currently running into an issue where whenever I play a video game with having the AC cord plugged in, the games will run at roughly 90 fps for a few minutes then the screen freezes and I'm unable to do anything / sometimes a strange buzzing noise comes through my speakers. Not all the time but its like a soft hum. I have performed Hardware tests on the GPU / CPU / Motherboard, check the ram, made sure my power adapter was good, all that fun stuff and I'm still unable to figure out what the heck is going on. Whats really confusing to me is today it will be doing this, tomorrow it could be working just find while being plugged in. I'm running a

Intel I5-2450m
8 gigs of ram
Nvidia 525m / Intel HD 3000
Windows 10

I was playing Dead Island and World of warcraft yesterday at 50ish fps and today its just completely acting up. Any ideas would be greatly appreciated

Tried other GPU drivers? What are temps like? Any minidump files or just hardlocks and you hold down power button?

Temps are in the norms, nothing that causes concern, the screen just freezes completely, my touch display works just find for some options, but my keyboard also goes out. I tested it twice after posting and the noise seems to be originating from what sounds like a loop error via sound when the game is playing. Because the louder the speakers, the louder the game. When I'm not plugged in the games run relatively okay. Just seems to only happen with the computer plugged in.

Upon further analysis I have noticed my cord is a little janky as well as my plug in for the cord, both are old and the input is lose, being a dual gpu system and the latter being relatively crummy, I suspect that having a game such as dead island running causes the intel hd 3000 to overwork and become unable to support the computer anymore and that my power cord might not be supplying sufficient enough power to allow the 525m to work properly, probably sounds weird but its really the only thing I can think of. (not overly great with computers so I'm assuming thats how its working)

I don't think the GPU power is "combined" that way when gaming. I have an Alienware M11X R2 sitting around that uses the Nvidia Optimus technology. Basically, it will use the integrated Intel graphics web browsing, ect. but switches to Geforce when gaming is loaded. I remember the Lucid Hydra tech from awhile back that could combine the two, but I'm not sure if it even exists anymore. However, since it only happens when your laptop is plugged in, and you mentioned the cord is a little loose, it could be some kind of bad connection, and not getting enough juice, or because it's drawing more when gaming/plugged in, if the connection isn't solid or intermittent, it could cause a crash from the power drop. Just my thoughts at the moment.

Just waiting for the new cord to come in, I've been testing it out more, sometimes it'll run the games just fine for a while, other times it'll lock up and blue screen me. No idea whats going on with it. Laptops.. Gotta love them.
