I have recently been having radiator problems! I bought a radiator from a salvage yard and replaced my old one which had a crack in it. Once I changed the radiator and flushed it, It wasnt a week before I had a crack in the same exact spot. In the top right corner of radiator. What causes this to happen, and shoduld I keep fixing the radiator or replace something else with it?

Flush the cooling system and block, change the thermostat, inspect the waterpump for leaks and replace if needed. Replace the rediator with a new one or get it rebuilt at a radiator shop.

It is hard to say what caused the radiator to crack again. It is used for one thing, you could have a bad thermostat, if using Dex-Cool, you may have a restriction in the cooling passages.
