Lately my desktop will spontaneously display vertical stripes that take place of the entire screen and the sound continues working for a few seconds and then it cuts out. The only way to restore the computer back to normal is to hold the power button to turn the computer off. Upon turning the computer back on, there are sometimes still visual artifacts on the black boot screen such as red and yellow lines that then disappear when the windows login screen appears.
Here is an example of what the screen looks like when this happens:

I have noticed that this more commonly occurs while gaming, but it has also happened while simply typing on a word document with nothing else open on a cold boot. For this reason I have tried to do a fresh install of graphics card drivers, I tried using different versions that were once previously stable on my machine. I reseated the graphics card and tried putting it into different slots. I even clocked down the frequencies on my graphics card by 300 mhz each using AMD catalyst control center and yet it still happened. The temperatures are all at normal ranges, and I've even see this crash occur while the card was at about 40 degrees Celsius. At this point I'm thinking maybe the graphics card is just dying? Or could this issue be caused by a different part of my computer?
The GPU is an AMD radeon hd 7970
UPDATE: I tried disabling HPET in my bios because it was on by default and I saw someone else with the same issue mention that. When I disabled HPET my windows login screen was covered in visual artifacts and the crash occurred as soon as I typed in my password and pressed enter
