Hello,
I've upgraded my GTX 1050Ti to Asus RX Vega 56 Strix OC. However when i boot the computer there is no signal on monitor and both my keyboard and mouse doesn't seem to power up. After some googling i found out its likely to be BIOS settings or PSU. However i just bought a brand new power supplier (EVGA750 BQ) to support the GPU so im thinking-hoping its not PSU related. Also since there is no display-keyboard when installing the vega 56 i dont know how to tweak BIOS settings. When i install the old GPU(1050ti) everythink works again. My GPU is connected to PSU with 2 6+2 pins, my motherboard is asus m5A97 LE R2.0 and my OS is windows 10 if that helps. I would appreciate any help since i really dont know what to do. Thanks

Yes i did uninstall the nvidia drivers with DDU sorry i forgot to mention that. Also the fans are working and the lights on the GPU are working too.

Make sure the card is fully inserted into the PCIe and that the PSU cables are plugged in. Vega 56 is a power hungry card but your 750w should handle it. While your at it reset CMOS just to make sure

Still the same :/ Since there is no keyboard/monitor i can not access to BIOS. I also updated BIOS with my old GPU didn't make a difference too

The card was new. I did manage to reset CMOS first nothing changed with the new GPU but when i install the old one again it got me to bios settings.

Do you have another PC to test the GPU, there is probably something else that is causing the issue but if you have a spare pc you can plug your gpu into to test if it isnt the GPU.

Unfortunately i dont have that kind of option. Is it possible to see if my PSU is working properly, like testing if it can provide 750 watt? since i installed it also along with the GPU it might be the issue as well.

I am suspecting there is a problem either with BIOS setting or GPU is faulty. Because when i insert the old GPU it works and the voltage values seems to be fine. I've tried to update the BIOS, resetting CMOS. I've heard people suggesting to try it with integrated graphics but my motherboards doesn't have one so i can no do that. Is there anything else might be causing the issue BIOS wise ? Or is there a way to check the GPU is faulty without insterting it to another PC ?
