Hi , I recently got a new gpu (4070 ti ) and a new power supply (750 w) I went and installed the power supply and gpu to my pc but after trying to start the pc it goes directly to the bios and I don’t really know what to do , is there something i should do before adding the new gpu? I made sure all cables are well connected. Pc specs :

Windows 10 Intel Core i7-10700(cpu) 36 gb Ram 4070 ti (gpu) 750 w for the power supply

Edit: I tried to add the old gpu and power supply again and see if the problem goes away, but now for some reason I have this issue ( it goes directly to the bios no matter what ) it doesn’t matter what gpu or power supply I have installed. I really don’t know what to do now
