Re: Computer died and it was my fault
It sounds like a power supply but it seems odd that it would die like that when you turned it off after running for 3 weeks. Running that long wouldn't have had anything to do with it going bad.
Does your motherboard have a power light on it? If it does, you can check that to see if the motherboard is getting power or not. If the light is out then the motherboard isn't getting power and I would say it's definitely a power supply. Just to check some things, you didn't accidentally flip a switch on a power strip or on the back of the power supply did you? Just a thought of something to check, stuff like that happens sometimes.
But I'm betting it's the power supply, I would go ahead and buy one and try it.
