I need help with my Acer Aspire 5920G laptop. Its original GeForce 8600M GT graphics card failed, so I replaced it with an Nvidia GeForce 9600M GT MXM card.

🧩 Initial Issue- Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight
- External display (HDMI) shows

Hi,
My daughter has accidentally managed to kill her Acer gaming desktop it has a blank screen after updating and when you press the power button the fans spin, light comes on and it makes 1 long and 1 short beep and no attempt to boot.
All basic troubleshooting has been done we replaced CPU, GPU and RAM from a working machine and no joy, I also noticed a post on here with the same issue and it was the BIOS. I am pretty sure also because it was doing a BIOS update that stopped it working, she knocked the keyboard out by accident during the update and the screen just went... -
