lol.. don't worry, my friend did far worst to his computer
He burned his Powersupply because he forgot to turn offed the surged, then he went onto burned another one because the PS fan was broken and overheated.
He killed numerous cdrom drives before, mostly because they're crap and snap. And then he went on to burned his Ram by accidentally set the Ram Voltage from 3.3 to 5v
He burned his old BE6 II mobo this one time from from screwed up jumper settings he was messing around w/ and didn't know what the fvck he was doin.
And the finally, he burned his then BRAND NEW Celeron 566 by not using the internal Voltage control in the mobo soft bios, instead went stright to the Slotket jumper, but well, he screwed up one jumper, so instead of giving the CPU the 1.65v that he intended it to, he sends 3.5V to his cpu. His chip died rite away, all the thermopaste had been burned off clean, and you can smell it in the room, the core itself, instead of dark blue/purple looking, it was completely black. As with the surrounding area.
Needless to say we all laughted our asses off about that one.
