When I turn on the power supply to my computer, my mouse's light light up signalling that power is running to my computer, when I push the power button to my computer, the fan inside spins, everything is working, then suddenly the computer switches off and the fan stops spinning and everything doesn't work, my mouse's light is still lit up so it means my computer is off and power is still being supplied to the computer. I tried to turn it on multiple times but it is still the same. Before this problem happened, I left my computer on for 15 hours for the FIRST time in my life, then I thought that I left it on for too long so I cut off the power supply, not use the power button to turn my computer off, I know it is bad but I was lazy and I did this like over 600 times already, just chopping the power supply instead of using the power button. So 1 hour later I switched off the computer, I turned it on, then that is where the problem starts. Please help me.
