PC starts up but shows no screen; some components have been changed. Looking for advice.
A few days back I started my PC and it powered on, but the screen was black and unresponsive. I attempted several fixes: swapped out the graphics card, replaced the power supply, updated the HDMI cables, and reinserted RAM and other connections multiple times. There were no beeps or warning lights from the motherboard—just silence. My main concern was whether the motherboard or components were damaged. Is there another way to verify this? Also, my Mac Studio works fine with the monitor, so the issue isn’t there. I’m running out of ideas. Any advice would be helpful!
Your CPU has built-in graphics, have you tried connecting a cable to the motherboard to check if it boots? You also mentioned replacing the PSU and GPU, testing the RAM—maybe the issue lies with the CPU or motherboard. Consider inspecting for bent pins on the CPU or reinstalling the CMOS battery.
When I connect to the onboard HDMI port, nothing appears. There are no bent pins since I haven't handled the CPU for five years after installation. The PC hasn't been moved or tipped over, and it booted normally four days ago before stopping completely.
I believe you focused on the most important components, and there might be two possible explanations: a faulty RAM or a defective motherboard. It’s unlikely the CPU would cause this since it wouldn’t power on if it did. However, I recommend attempting a CMOS reset on your computer first to verify if the BIOS is contributing to the problem.
Removed the CMOS battery for 10 minutes and then reinstalled it, but the problem persisted.
