Hello I have my first custom built gaming computer that I am having problems with. First of all I am pretty sure it is my GPU that is the problem. When i play certain games (The Witcher 2, Terraria, Bioshock, Skyrim, etc) and during videos from netflix and youtube i get little black dots across the screen or the whole screen goes into a fuzzy jumble of colors (sorry that's not a great description) or sometimes the screen just goes black but the game or video is still running and i can hear the sound as well. Right now all I do is Alt + Tab out and then it usually resumes to normal for a little bit. I would like to know for sure it is my graphics card because i dont want to spend money on a new one just to find out it was something else.
Here is my computer specs
CPU: AMD FX-4100 Quad Core 3.60 ghz
RAM: 8 GB
GPU: Gigabyte Radeon HD 6870
PSU: 500 W
Motherboard: MSI MS- 7693
Sometimes I even get the black dots on my desktop and browser. I have tried installing the most updated drivers and it has still persisted. I have been dealing with it for over a year because i thought i could fix it. What I would like to know is if this is definitely my GPU or if it could be something else. Also if I need to get a new GPU what would be a good recommendation for this system (preferably Nvidia).
If you need more information just ask.
Any kind of help would be very appreciated thank you.
