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?

my build is:
Rosewill Thor V2 Tower
Asus Sabertooth 990fx R2.0
Amd fx-6300 cpu
XFX XTR 650w power supply
G.Skill Ripjaws X series 8gb (2x4 gb)
LG black blu-ray drive
Seagate Constellation 1tb 7200 rpm 128 mb hard-drive
Samsung 840 pro series 128gb solid-state drive
Asus GTX 660 2gb 192-bit graphics card

I don't understand how I'm supposed to update the BIOS if I can't get anything to come up on-screen.

Nope it does not POST. I started going through the checklist and was wondering, for #2 do I only need the 4/8 pin CPU power connector plugged in or do I also need the 24 pin connector plugged in? What is the difference? If you haven't already been able to tell this is my first PC build haha.
