Turns out the problem originated from an incorrect cable attached to the psu mine is a corsair which i purchased used and came in an evga box...problem has since been rectified

ok so i have a fully functioning rig i7 8700k MSI Z390 A PRO WD 250 M.2 sata ssd only 1 sata port is being used from the 6 that come with the board melting occurred twice and from a different port each time as 16GB Corsair Memory Corsair Rm750x MSI GTX 970 The rig works without issue but i decided to schuck a WD 2 TB external drive which I'ved owned for about 5 years. to use it in my rig for storage hooked it up and attempt to power it on and the data cable melted at the mobo end ...smoke and stink coming out the front of my case twice since i tried a 2nd cable after the first one was melted.Same result again. powers up for a split second and shuts off and then the smoke. the satacables used were the ones provided by MSI that came with the board. power sata cables were provided with the psu i hook the wd interface back to the drive and of course it works just fine...fml anyone have an idea what could be causing the data cable to melt?

Thank you for the info

Well to give a short history of what happened...this tower belongs to my nephew...he built a few years back and it was idling close to 100° after he heard a popping sound from the tower. He didnt bother to fix but opted to build a new rig. Mind you he was using the old tower for about a month before he had the new rig ready to go so i assume the overheating happened several timesHe is offering the tower to me for 250 as is since he can't guarantee it wont crap out within a few days or mi utez for that matter. My thought was to build a newrig using only the cpu and replace everything else

Im curious to know if a cpu can be reused if after overheating. Im speaking about the i7 8700k. Is it worth it to attempt a new build with a replacement board and cooler and whatever else is needed
