Hello, I've had my ax1200i for 3 years now, it's been working great until a few days ago. After I use my computer for a bit my PC shuts off then my PSU shows a red light. I hold the power button on my computer to completelty shut it off, I then try to turn it back on, but it only turns on for a second then my PSU immediately goes to a red light. Once again I turn it off completely, I let my PC sit off for a few minutes, then when I power it back on my PSU works normally showing a greenlight, but after a while of using it my PSU goes back to red. I'm not really good with computers, so if I had to take it apart completely to troubleshoot I would be lost.
