Strange graphical problems when playing games on HP Pavilion dv4-1220us.

I recently purchased an HP Pavilion DV4-1220us, and right off the bat, I noticed strange problems when playing games. After a while, things get distorted and pixelated. So, I downloaded HWMonitor, and I noticed that the higher the temps get, the worse the graphical problems become.

I found this website, and went to undervolt my CPU. Long story short, the stock voltages were 1.125 V, which seemed weird to me. I was able to undervolt it by quite a lot and still not have it BSOD. Under a full load from ORTHOS, I saw a reduction from 90C down to 80C, but when I play games, I don't get that much of a decrease. Before, when gaming it would hover around 80C, and now it hovers around 75C. That's still a pretty decent decrease, but the graphical glitches continue to happen, albeit a bit less noticeably.

I opened up CPU-Z, and I noticed that whether it's undervolted or not, the voltage keeps switching back and forth between what it's set at, and 1.20 V. I've heard from a few other users that they've seen this as well.

Could this voltage fluctuation have anything to do with the graphical glitches?

Has anyone else with my GPU experienced the same problems?

 

Simple way to tell. Turn off under voltage and play the game. If you still have it then its the graphics card. If not its your under volt. I personaly do not like under volting.

 

I've had the problems since before the undervolt, and I was asking if the voltage fluctuation was behind the problem, not the undervolting.
Speaking of, is the voltage fluctuation fixable?
Also, if it's just the GPU, has anyone else had the same problem? Should I call HP and see if it's a fixable issue?
