My friends computer recently broke. He called msi, his gpu manufacturer, to ask if he could send his gpu back. They told him to test the gpu in another computer. The weekafter he called msi, he came over to my house and I installed his possibly broken gpu in to my PC. My pc would not post. I currently do not have a speaker so im not certain about it posting. We took the gpu out and I reinstalled my gpu. My PC would still not post. I am wondering if anyone has a clue as to what would be the problem in my PC because i want to replace the parts as soon as possible.
