It worked smooth whilst gaming, but suddenly, i get this.. pixelglitch/Polygon.. reminds of when i did 3D modeling and a polygon would be screwy.. what do? Got the newest drivers, on everything really.
Ah, it's a laptop, I was thinking it's a desktop video card. Run a benchmark like 3DMark, see if it does the same thing or locks up the PC. Card should be working fine no matter what you use it for, HP should replace it if it keeps happening. This could just cause a full system crash at some point if left alone.
