Start with a blank slate, learning PC building basics step by step.
Trying to figure out my new PC setup, it’s not working as expected. I installed all the parts today—Ryzen 7, graphics cards, RAM, storage, power supply—and everything seems to be connected. When I turned it on, the fans spun for a bit then stopped, followed by the RGB lights on the RAM staying on. After waiting about half an hour, I checked again and everything stayed consistent. I’ve double-checked the cables, replaced the RAM and GPU, and even tried formatting a USB drive to update the BIOS, but it still doesn’t boot properly. The CPU and memory error lights are active when I power it up.
I’m interpreting “doesn’t POST” as no output from the computer appears on the screen, such as the UEFI/BIOS interface. Here are some steps to verify: Confirm the CPU cooler and fans are properly connected; if a cooler isn’t detected, the motherboard might block booting for safety. Refer to your cooler’s manual for the right setup. Make sure the monitor is connected to the correct ports. For discrete GPUs like your 4070, use the card’s internal ports. Test with another device or port to confirm functionality. Verify the monitor settings are correct and that no other devices are interfering by disconnecting them. Since your system has built-in graphics, briefly disable the discrete GPU and rely on the integrated one for easier troubleshooting. If issues persist, provide a detailed list of components used (a link to your PC Part Picker Build would be very useful).
It seems there might be a power disruption. Have you attempted to run it without the 4070 Ti yet? Please proceed fully with the IGPU until the main system stabilizes. This could be an extra step right now. Do you have any photos of the external connections? If not, and if the issue isn't due to the 4070 Ti, then the CPU might not be properly seated or there could be a defect on the CPU or motherboard.
It turned out to be a problem with three of the four RAM slots. I wasn't sure why, but after trying it with just one RAM in slot 2, everything functioned properly. I sent the board in for warranty, and once the new RAM was installed, it worked as expected. Thanks for your feedback!
