Asus G20, installed Graphics Card, now no keyboard/mouse detected

[DonS]

Hey all!

Have an odd one. Client computer, an Asus Rog G20, replaced the graphics card with a GTX 2060. Upon reboot, BIOS states "Please enter setup to recover BIOS setting" and "no Keyboard (and mouse) detected" and will not let you proceed into BIOS or any further. (photo is attached, not users computer, but same exact message)

The initial fix for this was:
1) Turn off PC
2) Remove graphics card
3) Turn on the PC (using on board graphics)
(no more keyboard not detected error)
4) Enter BIOS
5) Reset bios to defaults, saving
6) Reboot then Shut Down
7) Install Graphics Card

The keyboard not detected issue arises when the power cord is removed. As this keyboard issue appeared wen the user booted up the computer at home. (he ran the fix above on my directions) then he apparently needed to move the computer, unplugging the power, and it occured again.

Google Fu shows maybe two posts about this occurring after putting in a new graphics card, but no solutions.

Any thoughts or suggestions on this one?

Thank you!

So after the system loses power completely, you turn it on with the video card installed and keyboard and mouse arent detected, if you give it a few minutes and hit the reset button the keyboard and mouse are never detected until you do that work around?

This is correct. After multiple restarts, the issue persists

That GTX2060 could be dragging down the power supply. That's a 160 watt card.

Well I had something similar with onboard taking over the video even though the video card was properly installed? Your problem almost seems to be something with the power supply not being strong enough.

Edit : Seems @Metanis had the same idea as me with the power supply not giving enough juice.

I just looked into this. The power supply he has is an external block (like a laptop) it is 230 Watt.

Apparently, this unit can also accept an additional 180 Watt power adapter to be used simultaneously with the 230 Watt

I also found this on the Asus website, so it appears you all may be on to something

- 180w Adapter only: GTX745 and 'lower end' vga cards
- 230w Adapter only: GTX750 vga card
- Both 180w+230w Adapters: GTX760 and 'higher end' vga cards

However, I would still be wondering why the keyboard / mouse would be detected eventually, versus not at all if it was a power issue?

Well if we we're able to help you in pin pointing the issue and that your able to find a working solution for your client.

It's a Win / Win scenario.
