AA-ron

Update: I found another video card (AMD Radeon HD 7700) in my hardware pile and swapped it for my current one. All the games started working again so I suspect that was the cause of my issues. Going to do some more testing, but I still think it's odd that it was forcing the system to reboot. It does require quite a lot less power to run so not totally ruling out PSU.

Thanks for the details, it seems to be happening with more and more things now so I would guess you are probably right with it dying from age.

Good to know about the warranty, thanks. I don't have another rig to test the GPU , but I would have assumed that running Heaven Benchmark would have caused a failure if it was GPU.

Will check the RAM. regarding the power I think based on performance requirement games can require more power from the PSU to run the hardware requirements (Just a wild guess though).

Now it restarts immediately

Description of the Issue: About a month ago I started to have some issues running certain games. When I started them up the screen would go blank (Monitors reported nothing was connected) and then eventually the computer would just restart. It originally started with everything locking up and I would have to perform a manual restart. Example (Overwatch works fine and the new Warcraft 3 crashes immediately. Computer Specs (Built 5 years ago): CPU: Intel Core I7-5820K 3.30GHZ Memory: Kingston HyperX Predator T2 16GB Motherboard: ASUS X99-A ATX LGA2011-3 Video Card: ASUS Radeon R9 390 Case: Antec Twelve Hundred 1200 V3 PSU: Corsair AX760 760W ATX 12V V2.31 Troubleshooting Done: Eliminated software problem by reinstalling both working and nonworking games and the issue persisted. Went as far as wiping the drives and reinstalling windows, but same issue. Thought about overheating so I used compressed air and cleaning off everything. I do have NZXT Sentry 3 5.4-Inch Touch Screen Fan Controller and it keeps temps between 30-60 degrees and I've never received alarms. GPU tested using Heaven Benchmark. Ran it for about 30min, temperatures stayed normal, didn't notice any display issues (stuttering or such). Last test I did was using FurMark and it crashed and rebooted about 30 sec after starting it. Final Thoughts: Just wondering If anyone can provide some advice or thoughts for next steps. I think it might be the PSU, but I wanted a second opinion before buying hardware. Any help would be greatly appreciated.
