CPU upgrade

Hi guys,
I currently have bought new cpu but for some reason system does not want to start. What could be wrong? I have changed information in bios and also upgraded it to latest version. When stick old cpu back and change details in bios for old cpu, everything allright.
I calculate power usage, seems allright.

My old system:
Gigabyte GA-890GPA-UD3H ver1.0
AMD Phenom II x2 550
2x2gb Corsair 1333Mhz + 2x1Gb Corsair 1600Mhz
Ati Radeon HD5750
PSU 650W

New system is the same apart of cpu which is AMD Phenom II x4 965

Some people here have said that a clean install or at least re-install of windows 7 is needed with a CPU change and for sure when you throw in a new mobo which I understand isn't the case here. What do others think, regarding this?

I swapped from an Asus P5Q Pro, Q6600, and 8GB DDR to an i7 870, Asus P7P55D-E, and 8GB DDR3 2 weeks ago and Windows booted right up, found the new hardware, rebooted a few times and I was good to go.
My Windows 7 Ultimate 64bit install is 15 months old now and runs great.

My brother did the same thing 2 weeks ago as well.
AMD quad core to an AMD 6 core and motherboard swap as well and his booted up just fine too.
