As you can see with the signature below I've got a good Computer
, now for the fun of it I decided to get a old Q-Tec 450w supply out of the Computer bits box I've got (bits from way back to 286/386 computers) and stuck it in this computer. Well all fired up ok and went into Windows (had to use converts etc for board and took one graphic card out), anyway I went onto BF2 and was gaming for about 15mins when the Computer locked up, so I rebooted and tried again.This time the Computer it was working for 12mins, when I could smell burning and before I could lean over and turn off the Computer, their was a quiet popping noise and the Computer shut off. I took the cover off and all looked ok, but to make sure it hadn't damaged the Computer I replaced the original power supply and fired up and all is working great again.
Right down to the Q-Tec (450w), I remove the cover and at least 5 components had melted (LOL) and the connector for the motherboard had gone black and melted at the -5volt pinouts.
It's completely dead, point of this story is get the correct power supply to run the Computer or it'll melt
