I have been working on a PC build for a while now and have been having a lot of trouble with it.I am using an Asus Sabertooth 990fx R2.0 motherboard and an AMD fx-6300 cpu. The first time I booted it up the cpu component light was red indicating there was a problem with the cpu so I sent it back to AMD for a replacement. Now even with the replacement cpu I am having the same problem. I find it hard to believe I have gotten two bad cpu's in a row. I tried calling Asus about it and was told it might be an issue of updating the software on the motherboard as it might be using something older than what the cpu is using. Also I am unable to get the PC to shut-down with just the case power button. Could this be an issue with the motherboard, cpu, or something else entirely?
