No POSTing after adjustments - dead CPU?

System Specs:

CPU: i5-750
Video: GTS 250 1gb
RAM: 2x 2gb OCZ3G1600LV4GK
PSU: OCZ 600W Stealth
HD: Samsung 1.5TB

I've been having some issues with my memory not being correctly recognized in W7 64-bit (OS reads 3gb when 4gb present) so I updated the BIOS in an attempt to fix it. I had my CPU OC'd to 3.2ghz and the BIOS update reset that to default so I fixed it. Upon reboot, the system wouldn't POST and the CPU red light on the mobo came on. System stayed on, all fans running. I cleared CMOS and it booted to Windows.

I then shut down and reseated my ram into slots 2/4 instead of 1/3 to try to get the RAM issue fixed. System again doesn't POST, but this time there are no warning lights. I put the RAM back and still can't get the system to POST. I took my CPU out and saw some slight markings on the bottom (pics spoilered due to size). Is it possible that my CPU is burned out? I should also mention that this system had been running stably since Nov 09. Any help would be appreciated.

  1. The pins look misaligned at the very least. And why did you put the image in the spoiler tags? Anyways, a burned CPU would at least have discoloration darker than what I see above.
