New installation not starting?
New installation not starting?
Hello, I'm working on a new PC build and have faced a problem where nothing appears when I try to jump the motherboard using a screwdriver. Lights are visible on the back of the motherboard while the PSU is active, but these don't seem to correspond to RAM, CPU, VGA, or boot indicators, which are located in front and not showing anything. The 24-pin connector for the motherboard and the 8-pin for the CPU are all correctly fitted with no gaps. I'm currently using the CPU's built-in graphics, but I've also tried using a GPU and the issue remains.
The unusual part is that yesterday, after setting up with the GPU, everything functioned properly—BIOS loaded, RAM, CPU, M2 SSD were visible. However, when trying to exit BIOS, it would loop back into BIOS without clear signs of failure. After a successful boot, I placed the motherboard into the case with the GPU installed; all standoffs were secured (8 total), headers connected, but the system wouldn't power on at all except for the backboard lights when the PSU was active.
I tested the PSU using a paperclip and it worked, though the fan spun briefly. CMOS was cleared, but the problem continues. I also tried with a single slot RAM module, which still didn't resolve the issue. CPU, RAM, M2 SSD, and GPU were functioning correctly the previous day, so these components aren't faulty. However, I suspect the motherboard might be defective—perhaps a short circuit occurred after installation. It would likely happen once the motherboard is fully seated in the case.
Any advice on next steps?
I would concur with this evaluation. Consider taking the motherboard out of the case and placing it inside the static bag it was originally in. Arrange all components and connect the cables as though operating within the case. Attempt to boot the system. If it functions properly without problems, you likely have a short circuit. Verify that the risers are correctly installed without excessive or insufficient connections. It might simply be a short caused during installation, especially if you built it in a carpeted area with socks on.
