Problem encountered with the new PC—power failure, urgent assistance needed!
Problem encountered with the new PC—power failure, urgent assistance needed!
Hello, I hope you understand. I’m really worried because my PC won’t turn on despite everything seeming normal. Here’s a summary of what I have:
- Motherboard: MSI B650 Gaming Plus WIFI, Corsair Vengeance DDR5 6400Mhz (CMH32GX5M2B6400C36W)
- CPU: AMD Ryzen 5 7600X
- No GPU yet (the 7600X has built-in graphics)
- Power supply: ThermalTake GF1 750W, Thermalright Frozen Notte
- PSU: 7600X model with integrated graphics
I’ve checked the connections and lights, but nothing seems wrong. The motherboard has two 8-pin CPU power ports, but I only used one because the PSU didn’t have a second. The EZDEBUG lights are on, and the VGA light is yellow—different from the others.
Things I tried:
- Put in an old GTX970; it worked fine.
- When the PC was off, the PCI-E light was lit, suggesting the PSU might be okay.
- Switched RAM to Corsair Vengeance, which is supposed to work.
- Checked compatibility of my original RAM with Lexar and then Corsair.
I’m not very tech-savvy, and I’m trying to figure out what’s going on step by step. It’s getting a bit stressful. Please advise!
I can help you retrieve an image of the lower half of the mainboard. Most newcomers struggle with setting up the JFP1 correctly—it's located at the bottom left. Use a screwdriver to short the pins 3 and 4 on the left cluster, then check the top row for the power switch connection.
I didn’t like the “beginner” remark, but I attempted to short the mobile PC at JFP1 about half an hour ago and it started working fine. I verified all connections are perfect, so it seems the issue was a faulty case cable! Much better than other possible problems.
You mentioned you weren't that computer. Great job spotting the issue, I'd recommend contacting the case manufacturer via phone or email to request a replacement. Most cases can be swapped out. Alternatively, you can initiate an RMA for the case. For testing, if it's not a block connector but just single connectors, you might connect the reset switch to the power_SW jumper pins.
