Hey so I always run my pc off my smart tv via hdmi cable. Last night I went to use it and my tv doesn’t recognize that my tv isn’t connected anymore. I noticed once I turn the computer on, it runs for 10 seconds then shuts off and restarts. My mouse normally is lit up all the time and now it’s not. My keyboard doesn’t work or have any lights on. I did notice that there is a red light on somewhere inside my tower. My cooling fans are all blue and now I see that red light coming through. Literally know nothing about them. Please help. Thanks for reading.
