Oh man, I just did something really stupid. I was replacing a power supply and connected everything (CDROM, hard drive, floppy, ect...) but didn't plug the power cable into the ATX connector. I plugged in the computer and turned the switch on for the power supply at it popped. Now the power supply won't work, and I tried a different power supply in the case, and the motherboard won't even lite up. Did I just like toast everything?
