Hi everyone,
I’ve read numerous threads related to this problem, and I’ve tried many solutions, but I’m at a loss, so here goes. My current specs are:

AMD Phenom X4 970
ASUS M5 A88-V Evo motherboard

This system has been running smooth now for about four years and has never had a problem. I wanted to upgrade my CPU, so I picked up an AMD FX-8350. When I seated the new CPU the system failed to POST. The computer will turn on, the fans will spin, but there is no display output or POST. I put the old chip in and it booted up fine. Here’s what I’ve done so far to try solving this problem:

Updated my BIOS to the latest version. The CPU is supported by the mobo according to the ASUS website: http://www.asus.com/us/supportonly/M5A88-V%20EVO/HelpDesk_CPU/

Reset the CMOS by both removing the battery and shorting the jumper.

Taken out every component except one stick of RAM and tried booting the machine with the new CPU.

Swapped the processors back and forth about a dozen times, so I think it’s safe to rule out that the CPU or some other component wasn’t seated or plugged in.

I know that DOA CPUs are very rare, but I can’t help but lean in that direction right now.
Thanks in advance for any help or advice.

Unfortunately not an option at the moment. I did manage to solve the problem, though. I went ahead and flashed to the BIOS version that first added support for this CPU. Seems counter intuitive, but it worked. Thanks for the replies.
Check the FX-8350 pads closely for any damage, or anything that could make the pads from making proper contact with the socket pins. The pads should be clean.

If possible try the FX-8350 in another computer.

If the FX-8350 still doesn't seem to work, then it may be faulty (rare for CPU's, but it happens).

In this case, the pins are on the CPU, but they're all clean and unbent.
