Accidentally damaged the MO while assembling a new PC for the first time. The machine started up, fans whirred, and the GPU lit up, but mouse and keyboard failed to respond when connected to the MO. The monitor showed no signal from the GPU. Was this due to the scratch? What solutions exist? Is the MO now unusable, or can a specialist repair it? I purchased components for 2k, intending to build it myself. Everything went fine until adding the GPU. I likely damaged the MO by forcing out panels needed for installation. I didn’t realize they were affected when trying to remove them. After some troubleshooting, the PC turned on, fans spun, and the GPU lit up, though the cooler made water circulation noises. I connected an HDMI to the GPU and keyboard/Mouse to the MO, but the monitor remained blank and peripherals didn’t activate. The scratches appear on certain areas of the MO. Could these be the cause? If so, what should I do? I can’t find a replacement since it’s my mistake, but is fixing it worth the effort? Probably more cost-effective than buying a new MO. Would it be possible to restore it to good condition, or should I consider replacing it entirely? I’ve attached photos of the damaged section to illustrate the issue. I’m hesitant to disassemble everything now due to fear. I also don’t know if I scratched the back of the MO, though I tried to handle it carefully. Additionally, I can’t power off the PC except by cutting off the power supply. PC specs: MO – MSI B650M GAMING PLUS WIFI CPU; GPU – ASROCK 7900 XTX; RAM – 2x16 GB 6000 MHz; SSD – Corsair Vengeance, Lexar NM620 M.2; PSU – Corsair RM850e; cooler – Arctic Liquid Freezer II; case – DeepCool MATREXX 55 MESH.
It’s hard to tell, but you probably used the 8-pin CPU connector. You can test it by removing the case and trying it on a simple cardboard box with basic electronics.
In retrospect, I've been considering whether the audio part would affect things at all—and I wouldn't be surprised if it didn't. That means another issue or something OP hasn't caught yet. It might be better to disassemble it and reassemble it in a cardboard box instead of the case, just to test it there.
Are there gaps between the motherboard and the case? Usually there are preinstalled standoffs on the case, but they should only be placed directly under holes in your motherboard. You’ve marked the surface, there’s copper, a coating over it, and you’ve scratched the coating—likely just a light mark, no broken traces. In the worst case, you might cut a trace, but since this area is linked to audio, it could affect the microphone input or speaker output. Alternatively, the system might have disabled onboard audio in the BIOS, requiring you to turn it off manually. Also, double-check that the front panel header was installed correctly. During startup, the motherboard may take a few minutes to initialize because it tests memory modules—patience is key. If the screen goes black, wait and try again.
I confirmed there were no standoffs. Previously noted red and yellow LED lights on the CPU and DRAM. After updating BIOS with Flashback, swapping RAM, and waiting, the lights faded away. I waited for BIOS to load but got nothing. Chose to connect the HDMI cable first, then powered on the PC. Now I’m trying to install Windows. The old USB caused an error—hope it wasn’t the hardware, just the system. Thanks for all the advice. I’m relieved the audio traces aren’t critical.
