Summary: I purchased this along with a Biostar A770E3 motherboard and all new components for a new PC build. This CPU is listed as a compatible device with my motherboard. When I put it together, the system would power on with fans and lights running but no video. I thought it was the video card at first but after trying it in a working PC it was not the video card. It was this CPU.
