I recently replaced almost every part of my old computer such as the motherboard, processor, graphics card and ram. My pc was running perfectly with all of the new compents and my old gpu (gtx 980ti) but when I replaced it with my new graphics card (gtx 1080ti) it worked perfectly until I ran Battlefield One and then it crashed about 30 seconds into a game after that it would refuse to start up. Nothing will power on and when I push the power button the lights will turn on for a millisecond and the psu will make a noise but that’s it. I’ve tried different surgeproctectors and outlets and nothing. I unplugged the gpu and it finally powered on but didn’t run. I also replaced it with my old graphics card and it’ll power on but won’t start up. I’ve tried to get into the Bios but I haven’t been able to. I’ve went through the entire computer checking each inch for anything out of place and everything is how it should be. If anyone has any idea what the problem could be or how to fix it I’d be grateful.
UPDATE 1: New Psu didn’t do anything, it started up when I unplug the gpu but still wouldn’t actually run.

Update 2: I was able to start up my pc and run it fully without a graphics card. I am going to attempt to see if it will work with my old gpu.

Update 3: I was able to start it up and it ran perfectly with the old gpu but when I used the new gpu it wouldn’t start up at all like before

Update 4: the Asus strix is 1080ti right 8-pin cpu cable slot works alright but the left one is the reason the computer wouldn’t start up.

Have you tried different PCIe cables at the left slot? If yes, and it did not work, the only logical solution is that 1080ti got fried (specifically the left slot got fried).
