Games that I could run well yesterday are not running well today.

I was playing EUIV yesterday, and I had a massive lag spike in the middle of the game that made it unplayable, it has happened with every game I try, even games with pixelated art styles. My specs are:
CPU:Intel i5-3450 @ 3.10GHz
GPU:NIVDIA GeForce Gt 620
RAM:8.00 GB
OS:Windows 7

Make sure your GPU is updated to the latest patch.

Check your gpu temp while playing.
