I have an p7h55-m Asus mothabord it’s and lga1156 socket cpu and it currently had a core i5 650, so later on I decided to buy the core i7 870 on amazon used, I’ve always bought used cpus and it always worked, but this one completely ruined my motherboard and it’s a huge nightmare for me. When I installed the core i7 onto my motherboard and checked everything to make sure it’s fine when I turned it on all the fans were spinning really fast, then oh I forgot to plug in the 4pin cpu power, so I turned it off and plugged it in, right after I turned it on, few seconds after one my mofsets whatever you call it, near my EATX plug went smoking so I shut it off. And tried the original cpu and thought it would work but now my Mobo is completely dead. I’ve been searching online and looking at peoples article to see what could’ve caused this, but I just couldn’t find one. All i can ask is that, is the core i7 too strong for my motherboard that it just smoked out of no where???
