I am trying to solve a problem with my monitor going black while I’m playing games. I had been playing on this rig for about 9 months when this started. I originally began having problems back last summer when my games would occasionally go to black screen for a few seconds before resuming. I updated my drivers and it didn’t seem to fix the problem, but it was only happening once every 3 hours or so and then only rarely. Then after a few months I started having full crashes with the screen going black – on occasion it would totally crash the computer, but most of the time the computer was still running, just with a black monitor. I did some online research and the problem seemed to likely be the graphics card. I tried it in another computer and had similar results. Elated, I bought myself a new card (same model) for Christmas and figured I could go back to gaming.
Only, now I’m having similar problems. The screen goes black and the computer is unresponsive (sometimes I can still hear the music from the game, sometimes not), I have to restart to get it to work. Thinking it might be the same problem I returned the new card and got a replacement – only to have nothing fixed. Now I have an added problem of the first PCIex x16 slot seeming not to work at all now (when I have the graphic card there, the monitor will not respond at all even during start up). I moved the card to the second slot and the monitor responds but I still have the crashing problem in game. This is making me believe it is the motherboard, but I can’t find anyone online who has ever seemed to have these symptoms and have the problem be due to the motherboard.
I have never had a crash not playing a game.
Things I have tried:
- Checking the temps – the game often crashes early in, so temps rarely get a chance to get high. On last crash GPU was 40C and CPU was 32C. Idle runs around 23-28C for CPU and 25-30C for GPU.
- Different monitor cords. I have 2 and both work with my laptop and the monitor.
- Cleaning the fans.
- Made sure all drivers are up to date.



Any help/thoughts on other tests to figure out what exactly is wrong at this point would be much appreciated.
 
When you got black screen, but can hear sound, usually that problem related to display only, like GPU, PSU, monitor, GPU driver and temp. Because you did try other troubleshooting ideas, like different cables, check the temp, update the drivers. So may try:
1) I am not sure when you switch the GPU, do you use the DDU to uninstall the driver in safe mode then reinstall the driver again? If you don't, and try it. DDU http://www.guru3d.com/files-details/display-driver-uninstaller-download.html
2) Go into the BIOS check the 3.3V, 5V, and 12V, then make sure the PSU is good enough. PSU Voltage Tolerances http://pcsupport.about.com/od/insidethepc/a/power-supply-voltage-tolerance.htm
3) You said the pcie slot had problem before, how about take out the gtx970, just use the onboard iGPU, I know the intel iGPU is not good for games, but you may try it in low setting. If the PC runs fine, and because you update the driver ( if you mean the chipset driver), then maybe the pcie slot has problem. For the Z97, the BIOS maybe not the problem, if the MB is old model, sometime you need update the BIOS.
4) When the RAM is going to die, it may cause the PC to freeze too, may try test the RAM by MemTest86 http://www.memtest86.com/download.htm

And after you try those, one more to do: update the BIOS, if you still have the same problem, I think it is the MB problem, because the 1st pcie has problem, even the 2nd one has problem too, the PSU, GPU, monitor/cable is good, the driver, BIOS is up to date, so contact MSI to RMA the MB.
