Recent computer lag spikes

Since about last week or so, I found that when I'm trying to run specific things (like playing osu or watching videos on tudou, but if I leave the computer on long enough it'll eventually spread to near every other application), the computer will eventually suddenly goes in a lag spike, slows down to a crawl, and recovers only a few minutes later. Nothing takes up an unusual amount of CPU usage in my task manager either, and as soon as I close down whatever application's causing the lag spike, it'll just start displaying something else (like firefox or even explorer.exe) as gobbling up the CPU usage instead. I tried system restoring to a week ago, uninstalling applications I installed last week, and checked my hard drive for viruses, and I got nothing.

Does anyone know what's going on here?

Could be anything. Are you using latest video card drivers? Or did you update them recently?

Haven't touched my drivers for a while, so it's probably not that.

EDIT: Nvm, I figured it out. The thing's overheating. Guess I should turn it off a bit more often.

You might consider buying an exhaust fan that fits in a PCI slot like these.

There are external cooling options available for laptops.

I was using a laptop quite heavily until recently. Heat was a huge problem sometimes. Here's what magic tricks I used to cool it down, in order from the obvious and easy things to desperate need:

1: Cleaning the filter/grill that the air is exhausted through. It gets blocked with dust easily.
2: Using a small book (Even better would be actual design goods like cooling pads) to elevate the laptop and improve airflow under it.
3: Undervolting
4: Removing whatever heat conducting material is between the CPU/GPU and the heatsink, and replacing it with some quality thermal paste.
