My PC disk-drive wasnt working, but I needed to acess a disk. So, I got a disk-drive borrowed from a friend, I opened my PC, removed my drive and inserted his one.
When I turn on my PC.. POOOOWW! A high noise and smoke all over the place. I said "What the fuck?", I turned off the computer immediatelly, and checked all the wires. Everything correct. I turned it on again, but now it wasn`t working.
The Motherboard just blew up or something. And the disk-drive also stopped working too. I never knew what the hell happened that day, but at least that made me buy a decent motherboard (the fried one was a crap PC CHIPS all onboard), and my rather good for the time TNT 2 videocard.
