New cpu, pc wont boot up

[sleepy _head]

Hello, i'm new here.
I've bought an old cpu i5-2500 from ebay to replace an i3-2120.
I have tried to start up my pc with the i5, but all i get are regular continuous beeps and it wont boot up.
 My mb is really old (Acer Ipisb-vr rev.1.01 h61, lga 1155) from an acer aspire m1930, i've tried everything with the i5 but idk if this cpu is fault or it's not compatible with my mb.
I need help thanks!

usually it beeps a certain number of times, stops, and then begins again

Have you tried updating bios? Try it with a fresh install on a clean drive.

as qupter said,you should reinstall your old cpu and update to the latest bios you can get update us if its work.

also i know that on some old pre built machines continuous beeping means no ram detected,check to see if there is some dirt/thermal paste on the gold contact on the cpu,also try resetting the cpu.

keep us updated,and good luck.
