Your old cpu was a 95 watt cpu and your new one is a 125 watt cpu. Your motherboard may not support the higher voltage. Alot of oem's at that time were using up older motherboards from the original phenom cpus and 95w phenom ii's would work on them but not the 125w cpu's.
So sorry you are out of luck. Good news is that 1090t is still very easy to unload on ebay.
