My screen will just go black and a 50/50 chances that my game will still work or I have to shut the game down. Also any videos playing turns green.
- First of all, try THIS. (Taking a screenshot of crash entry in Event Log and posting it here would help since it will tell us which module is actually crashing.)
- Update your MB drivers - your PCIe controller drivers might be outdated.
- Southbridge might be overheating.. Not excluding the chance of Northbridge misbehaving (read: overheating) as well. Southbridge is located close to PCIe ports on the motherboard so if it's overheated - it could affect GFX card in PCIe slot. Northbridge handles communications coming from PCIe port, so if it's overheated - PCIe port might be failing. To collect data about these bridges go to the next bullet.
- Download and install PCWizard and post screenshots of Temp and Voltage and Global Performance Benchmark results.
- Do you have an integrated GPU? If you do - could you please make sure you have it disabled via Device Manager?
- Another possible cause of the problem - PSU. It might be either faulting or not having enough Watts to supply your GFX. Provide specs for your PSU and see if you could get a spare one (with higher maximum output power) to test.
