BSoD

I dont know if this is the appropriate spot for this but BSoD error generally means something connected to the MOBO issue. this isnt really a(n) issue its more of an annucense. what it is is a qucick BSoD error that happens right at boot then my computer restarts itself then it works fine. i checked to see if anything is broken or fried or if something is getting hot and everything checks out. my 3dmark score didnt drop my games run fine and stress tests say im good to go. now this only happens when i turn off my PC then flip the swich on the back of my PSU, when i turn the PSU on the my computer i get a BSod flash for a second then a reboot then it works fine. but if i turn off my PC and not the PSU and i go to start it i dont get that issue. so this leads me to believe this is a PSU issue. my PSU model# is this " BFGR1000WEX " just google it and you will see its not a cheap nore a bad PSU. this all started happening when i was working on my wireing on my Cooler master HAF 932 and plugged all the case fans into molex connectors and plugged it into my PSU. could this be the issue of the BSoD and if not what might be causing this.
