Yeah they are both LGA 1150 and so is my motherboard

Both cpus are compatible but you will need to complete a bios update with the I3 to allow it to work with the I5.

 

It's lga 1155.

They'd be LGA 1155 but no biggie. You need a BIOS update to run the ivy bridge CPU. So reinstall your old one and go to your motherboard manufacturer website.

Look up your board and get the latest BIOS available. After you flash it you should be good to go to install the new CPU.

OK thanks for the help.

Hey Bulldog651,

 

As the guys pointed out, you most probably need an update on the BIOS. Check the motherboard's manufacturer's website for the latest version and instructions on how to do it. If you need help, call the manufacturer's support, go to a repair shop or simply post here and some of us will give you guidance on how to proceed. If that doesn't help, do test the CPU on a compatible motherboard to make sure it is not defective.

Check the CPU socket for bent pins. Also pop the battery out and let it sit for a few minutes to clear the CMOS. Might help.

As @ApolloX75 suggested, make sure the socket is fine and not damaged or defective. 

Resetting the CMOS is also a good idea. If you have a spare motherboard that you can test the CPUs on, do try that.
