I did something stupid and need your help! My P4 computer won't turn on. Here's what happened. I had taken out the cd burner to use in another computer and was putting it back in this one. When everything was hooked up, I plugged in the power cord and reached around the back to turn on the power switch. I hit the 230/115 switch by accident and moved that over to 230. I thought I had moved it back but I didn't check. I pushed the rocker switch on the PSU to the on position and went downstairs. I never powered up the computer. I went downstairs and shortly after heard a noise and went upstairs to see what happened. The power supply was smoking so I unplugged the power cord from the computer. I fried the PSU (I didn't know why until later)but thought the computer should be ok since I never turned it on. I got a new PSU and tested it so I know it's good but the computer does nothing when I push the on button in front. Did I fry the motherboard too? What are the chances other components are damaged? Thanks for your help!
