It was my initial build when inserting the 18-pin connector into the PSU and the 24-pin into the motherboard, everything turned on briefly before shutting off repeatedly. When I tried the other 10-pin and 24-pin as intended, the system stopped completely. Should I replace the cable or the PSU? Or is there a problem with the motherboard?

Hello, I’ve successfully booted everything and the case power button wasn’t fully connected when I tried to turn it on.
Now I’m facing another issue – no signal appears on my monitor.

Specs:
- PSU: Msi mpg 750gf
- Motherboard: MSI MGP 750
- CPU: Ryzen 5700G
- GPU: Radeon RX 6600
- RAM: Corsair Vengeance RGB Pro 2 x 8 GB, 3600MHz
- Storage: Western Digital SN750 M.2
I’ve updated the BIOS using Flashback and confirmed the motherboard supports the CPU. No debug lights are showing.

I’ve tested various HDMI and DP cables, removed the CMOS battery, and re-downloaded the BIOS. All fans are functioning properly, including the GPU fan. Should I consider an older BIOS version? I’m stuck – everything seems new and compatible. Any suggestions or alternatives?

Power from the PSU is linked to the RX6600. With the RX6600 removed, the outputs on the card should function properly. Have you attempted this with the 5700g using the motherboard's outputs?
