Computer was running great, bought a video card from Amazon warehouse which had all sorts of issues. I returned it and bought a brand new card but bsod problem persists. I've tried everything and now reinstalled Windows 8 which hasn't helped. Could that faulty card have damaged my system to where it will cause BSODs? Hope my motherboard isn't damaged now

System is a 3930k Evga dark 16gb crucial ram 256gb Samsung 840 pro 780 gtx 1000w cooler master psu.
Any advice is really appreciated. Thanks
