So i pluged in one of the dell optiplex sx 270 and it started up just fine ran went into the bios and bam sisel sound and smoke comes poring out the back of it i unplug it and open it to find smoke lingering around in it but no burn marks no were took every thing out looked at the psu no burn marks but there but i haven't checked inside of it i looked at there thermal compound is pink could it be fake or cheap compound because the dell ran fine with smoke coming out btw there was no dust inside the dell i cleaned thats out with a air compressor.
