My computer started crashing a few months ago, but it's only occurring during gaming, usually after about 5 minutes of gaming. When it crashes, I cannot immediately press the power button again to turn it on. Instead, I have to disconnect the power cable from the power supply, wait about 15 seconds, and then I can start it again. I needed a video card upgrade anyways, so last night, I went out and bought a NVIDIA GeForce GTX 750 Ti. After installing it, I believed my problem to be fixed as I played "Life is Strange" for about 3 hours with no issues. Today I'm at work, and my wife tells me that after an hour of gaming, the computer crashed again.
My build looks like this: Motherboard: M4A79XTD Evo Processor: AMD Phenom II X4 GPU:NVIDIA GeForce GTX 750 Ti I'm dual booting Windows 7 and Linux.
Given the way that I have to disconnect power to the power supply before I can start it again, I'm assuming that the power supply is failing. Would that be a safe assumption?
