Power supply and shorting out.
I recently built my first computer. I didn't know however of the different motherboard/power supply compatibility issues. Meaning, 20 vs 24 pin power on the motherboard. A friend of mine that has been building computers for a little while said that I would be very lucky if I hadn't fried my motherboard.
I plugged a 20 pin PSU into my motherboard, which is a 24 pin. Since I didnt know what could happen, I turned it on, and the fans worked and the light on the motherboard lit up, but no image appeared on my monitor. Later I found out that the monitor may have been faulty, and that I did some other things wrong.
My question to anyone is: Do you think it fried my motherboard, doing what I did? Even if it did, it will only be 75$ to replace it.
