GPU & CPU freezing up/utilization dropping in games

I have an ASUS laptop (not a gaming laptop, but reasonably powerful-ish) that I've been playing games on for some time. These games include War Thunder, Fortnite and BF4. I recently bought Insurgency, which it can run fine, however after about 5 hours of play I noticed the game beginning to freeze up and stutter a lot. (Maybe every minute or so the game would freeze or the fps would drop to something awful like 5fps, for just a few seconds, then it would be fine again.) Thinking it was the game, I switched to Fortnite only to find the same thing was happening, even though it had never happened before. It now happens for most games I play, and at one point it got so bad that it would happen just about all the time so my game was in a constant state of stuttering and freezing. I've looked at task manager and whenever it stutters or freezes, both the CPU and GPU utilization momentarily drop by about half.
I booted up War Thunder instead after this problem only to find that it was running on minimum graphics settings. It was perfectly smooth, but I couldn't raise the texture quality higher than 'low' as the game said there was 'insufficient video memory'. I was previously running with high textures so I know there's plenty of video memory there.
The only thing I can seem to think of is that for some reason my dedicated VRAM or GPU memory isn't working, or is broken, although I'm not sure why this would affect the CPU.

My specs, if this helps:
OS - Windows 10
CPU - Intel I7-5500U (Dual core, 3.0GHz)
GPU - Nvidia Geforce 920M, 2GB (I think) dedicated memory
RAM - 8GB
1TB HDD, pretty slow, but it's not caused any problems before
Apart from that I don't know anymore details, it was a laptop that I bought, it's not like I built it.

you can do the following :
* fresh install of windows
* reinstall the latest drivers for your laptop starting with your chipset drivers. then your grpahics. then the rest. BIOS may be necessary.
* upgrade to at least a 2x8Gb 2400Mhz RAM
* optimize your OS virtual memory
* lower resolution and antialias graphics settings in highend games since you only have 2Gb of vram. also tweak other graphics settings. or just use the Geforce experience. slide towards performance instead of quality.
* clean your laptop fans/heatsinks of dust

I seemed to fix it by simply unplugging the second monitor that I was using for browsing/YouTube and playing some less demanding games. No idea why that worked and I hadn't though to try it but it's done the job

[strike]you can connect your 2nd monitors display cable to your motherboard instead. to lessen the load to your GPU. and just play games on your primary.
[/strike]
nvm youre using a laptop after all. i guess your system cannot handle dual extended. just use your extended monitor as your primary only.
