Hi All I put an add on the list but I wanted to see if anyone had any ideas on what to do first. The case I put my old motherboard and other parts in may have a nasty short in it. I believe it blew my Tyan S2390 motherboard (sniff, sniff). Thought it was the power supply but a "new" power supply didn't do a thing. It could be the power switch but I doubt it. I pulled the motherboard out and tried to power it up outside the case but it didn't work (I used the power switch from the bad case) I want to test the parts Processor, Memory, and other stuff to see if they work (I really hope they do). Does anyone have a motherboard for an Athlon Thunderbird 750Mhz I can use for testing and possible purchase or trade? Yes I'm getting a different case! Thanks Sam.
