a couple days ago i was working on my step mothers computer installing more RAM (256MB) I turned the computer back on and seconds later i smelt burning metal. I quickly unplugged the computer and opened it up and removed the RAM I had just installed into the PC. I smelt the RAM stick and it didnt smell like it was burning. It so happened to be that the burning smell was coming from the power supply. I then was worried that maybe the motherboard or something else got fried because the power supply powers other parts in the computer. (hard drive, CD-Drive, etc.) I took the power supply out of MY computer (which is the same brand power supply that is in my step mothers computer.) I plugged it in and it wasnt powering anything up.. only a green light came on one of the CD Drives and the fan was spinning very slowly. I have no clue what to do now. I am lost. does anybody have any ideas on what i should do? or if there is a way i can tell if the motherboard was damaged by looking at it?
