System won't boot after CPU upgrade. Should an i5-3550 work in a DQ67EP board or did I get a DOA CPU?

I upgraded the CPU in my system and after the upgrade, the system powers on, all internal lights and fans come on, but I get no video and no beeps. I re-seated the RAM, tried booting with no RAM, removed the PCI NIC, and even swapped the PSU with another known good unit, all no joy. Finally I put the original CPU back in and it boots fine.

It's a mini-ITX system that I built a few years ago as a storage server. The main components are:

- Intel DQ67EP board (LGA1155 socket)
- i3-2100 CPU (Sandy Bridge)
- Single G.SKILL DDR3 1333 8GB memory stick
- 550w PSU
- PCI NIC
- Using the onboard video
- 2 internal SSD's, several external USB and eSATA powered arrays

So aside from the external storage, it's a pretty basic system.

I run a VM on it and it runs fine, but I occasionally do some batch video encoding on it that can take 12 hours or more to complete and I wanted to speed it up so I decided to upgrade the CPU. Obviously LGA1155 components are out of production but I found an i5-3550 at a reasonable price so I bought it. It's an Ivy Bridge and my current i3 is a Sandy Bridge but based on the research I did, I thought the i5 should work.

Any thoughts? Should the new i5 work in this system? Did I just happen to get a DOA CPU?

Should have googled.

Ivy Bridge will run on Intel 6-series chipset motherboards, provided:
•They use the following chipsets: Z68, P67, H67, or H61 (Q67 and Q65 are not supported)

You have Q67.

Damn. Alright, thanks for the replies. I thought I searched enough but obviously I missed that.
