i know this is off topic, but lets face it most programmers are very computer intelligent

when i went to my secondary computer it was off. Strange I never turned it off. I tried to turn it on. Nothing. I made sure everything was connected correctly. Yep. Nothing. I though ok bad power supply. So i ran to the store bought an antec 300w power supply put it in and it ran for about 20 secs then it started to smoke from a chip not cpu on the motherboard. Disconnected power asap from power supply. I took out all the pci, agp cards and the hd and the everything execpt the motherboard, cpu and one bank of memory. Turned it on and it started smoking a little bit more same place on motherboard. So i dissconnected it completely and came here.

Has anyone had a similar experience? Is it a defective power supply frying my mb? Is my hd fryed it was connected during the first smoking? Any thoughts

again sorry this is off subject, but i need help
