Excessive Lag Spikes In PC Games?

Alright, so first my specs:

Processor: Intel(R) Core(TM) i3-2370M
CPU @ 2.40GHz 2.40GHz

Installed memory (RAM): 4GB (3.87GB usable)

System type: 64-bit Operating System,
x64-based processor

This is indeed a Windows 8 laptop. More specifically, it's a Dell Inspiron 3520.
I know it's not a fantastic PC, but it serves me well for my games, homework, etc etc… Until recently that is.

When I first got the laptop, all my games ran smoothly for the most part unless the area was overcrowded or heavy in graphics. However I always chose the lowest graphic settings for all my games so it would be much easier for me.

One of the first MMOs I downloaded was Neverwinter and it worked fine, but as time passed my computer began to lag… Heavily. At first I thought it was my internet connection because it's not fantastic, but that's a different type of lag than lag spikes. I now get spikes every few seconds from when I start my game to when I close it. Of course the smaller the area I'm in, the smoother it runs, but I used to not have problems like this whatsoever.

I checked for viruses and cleared my RAM up a bit to see if it helped, but to no avail. I noticed that when I play games my laptop overheats rapidly, and I'll usually only have the game and maybe the launcher open. Here are the programs/games I use:

World of Warcraft

Answer: Your CPU and/or GPU is/are overheating and throttling down (worsening performance, hence the lags spikes).

Laptops really aren't mean for gaming unfortunately. The heat produced is a lot and there's barely any room to go. Trust me I have this problem but I've tweaked it enough to where it doesn't throttle.

Solution: There's little you can do but you can look up ways online of how to keep your laptop cool (cooling pad, replace thermal paste, change power plan, clean out fan/heat sink, removing your battery, etc.)

Hopefully they will help keep the temperatures down a little bit more. Although laptop components are meant to withstand the intense heat, it still isn't excellent for the longevity of the computer.

Download RealTemp or such free non-virus CPU/GPU temperature checking programs.

My laptop peaks at 85 degrees celcius which is about 195 degress fahrenheit lol, but that is normal for my laptop's heavy processor.

Best of luck,
