[SOLVED] Why is my graphics card not working

[Deno_]

Hello, I recently bought a new gigabyte geforce gt 1030 low profile graphics card to replace my AMD Radeon R7. The poblem is whenever I install it my computer won't turn on, but once I take it out my computer works perfectly again.

List full pc specs.
Are you sure the 1030 works? (especially if you bought it used)

Sounds like a faulty GPU. What are your full specs and or make and model of prebuilt?
