I was hoping someone might be able to help me diagnose my issue. (PC specs below)
I purchased an AMD 6770 card in July and did some very light PC gaming.
In August I would play iRacing for 20-30 minutes and then the screen would eventually turn black for 10-20 seconds and then come back, until it eventually crashed completely. So I stopped playing iRacing.
In September I started playing CS:GO and after 5-10 minutes I would have FPS issues, the screen would flicker black, sometimes it would turn gray with black lines going down the screen and eventually completely crash. I finally found out that AMD Catalyst Drivers had the card overlocked by default under "Overdrive Settings" I found that turning off the overclock and setting the fan to 70% fixed my CS:GO issues.
Tuesday I started playing Planetside 2, and now I'm having the same exact issues as I had with CSGO. After playing I even have to restart the machine because I tried browsing Chrome and it just showed up with black/white boxes all over the screen.
In October I upgraded my processor/mobo/ram to an MSI board, i5 CPU, and 8gb RAM. I have a fan blowing directly on the graphics card and as I stated earlier have the FAN set to constant 70%. When monitoring the temperature it never runs hotter than 40 degrees C.
