I put together an apu build using the amd 7850k, MSI A78m-E45 mobo, rosewill galaxy 2, a coolmax cl700b I had lying around along with some leftover ram, and a seagate hd. I put everything together making sure it was in the correct spot the correct way. I hit the power button and all the fans turned on but nothing appeared on the monitor. I tried plugging in a mouse and keyboard and they didn't power on. I took everything apart as carefully as I could. I then tried breadboarding. I first tried it without the ram to see if the case speaker would beep but didn't. I then tried another psu. Agin no beep what so ever. What could be the problem? What do I have to replace?

I've been told by a few people that since my mobo is older than my processor I need an older processor to start it with and download the drivers that way. But is there a way I can download the drivers from one computer and and then attatch the hard drive to the 7850k one?

I know I'm a little late on this I have been gone a lot. I bought an older cpu and tried that but still nothing. I ordered a new MSi A88XM gaming mobo and am going to see if that works. If it doesn't then I guess I might have 2 dead CPU's? I know for sure my DIMM is working correctly and fine. My PSU is in full working condition. My assumption is It has to be a dead mobo. When the new mobo comes in Ill post and tell if it worked or not.
