Hello, yesterday before I left for my brother's House my computer was working just fine, I may have turned it on that session by hitting the reset button, don't know if that would cause any problems or not.. But 2 hours later I came back home to turn my computer on, and my computers fan lights would just blink and turn back off. The very back fan in my PC would turn on for like a second and turn off. Nothing is turning on the lights do but for only like a second. On my motherboard the green light is on and so is my Ethernet Light. I have changed the power cord, and even changed electrical plugs and still nothing. I am using the Apevia Iceberg 680W power supply, at this point I think it's the power supply. Please help if you have any solutions or second opinons.
