The games I played were
Hawken (I think that was the game's name, the one with mechs)
CoD 4: Modern Warfare
Minecraft
PlanetSide 2
Now they all have the same kind of lag (after ever second or two there's a second of slowdown then back to normal then slowdown etc etc etc)
Also my laptop (windows 8.1. Still this gaming one) started making random noises once in a while for no reason (that usb sound one… Or the one where there's a confirmation popup if you were installing something) but there were no messages at all…
Then when I would be typing it would just disselect the typing thing and I have to click on it again.
I only had this laptop for a few days.
The only things I remember downloading today where the GeForce Experience, Skype… And then CCleaner(but I downloaded CCleaner after I found the problem because I wanted to fix it with CCleaner… Didn't work though)
Added (1). What I'm getting are lag spikes of death. Like in minecraft where you lag every 2 seconds… Except I get that in all the games on my computer. I tried fixing whatever I installed that made it lag (I'm guessing the NVidia GeForce Experience drivers) by restoring the system but the only problem I got was all my desktop icons deleted, windows apps all have to be re-downloaded and all of a sudden it says my windows thingymajig is expired on the Store App.
