Hello, i have a Palit Geforce GT 620 2GB Version and i wanted to put in a old Q9500 system. But for some reason, the system wouldn't post, just a black screen. I was concerned that the system may not be fine and i was sure that the gpu is in good condition, but ironically the system post with a GTX 750Ti and when trying the GT 620 in my i3 7100 system it didn't work. Is there any way i could resurect or get that gpu working without giving it to repairs?
