Performance issues on Asus ROG G750J Series laptop

[Carro]

Hi everyone, I just got a new gaming PC and I've been quite disappointed in it's performance. First things first though, here are my specs;

OS: Windows 8.1 64bit
Graphics card: NVidia GeForce GTX 770M
Processor: Intel Core i7 4700HQ CPU @ 2,40GHz (8 CPUs)
RAM: 16GB
DirectX 11

I'll post the entire Dxdiag log if anone needs it. Now I haven't really been able to play anything without lag so far, here are the games I've tested; Guild Wars 2, lagged even when lowering all the graphics settings. Neverwinter, same as GW2. Now those two are at least somewhat understandable but I've also gotten severe lag issues in League of Legends, and I don't think that game is very demanding. It's worth noting however that this lag doesn't ALWAYS happen. Sometimes at least League of Legends works like a dream but then after a reboot it'll be the same laggy mess. I do like this PC but I also want what I payed for so any help at all is greatly appreciated.

PS. I've seen similar threads on this forum before but none of them had any real answers.

What storage unit do you have it stored on? Because I know a couple of the new G750Js have multiple storage options.

As far as I can tell it has two main storage units, one called OS (C: ) and the other DATA (D: ). Most of my games are installed on the DATA one though. OS is 95GB the other one is 121GB. I'm not sure how to check exactly what models and such those storage units are though so if you need to know that I'll need some tips.
