I'm not thinking it's my video card, I'm factory resetting my computer and dusting it out, that should help better.
You never know, you guys should dust your computers out, meaning taking the body off and blowing the dust off the fans. The fans is what effects your computer, if your computer isn't getting a lot of air, it's going to lag or be slow. I had Gmod which was really slow but after dusting it it was way faster, try it.
