System powers up yet display remains blank.
System powers up yet display remains blank.
This was my first time assembling a PC and everything turned on when I powered it up. The GPU lights up, the CPU cooler is running, and the power button light is on. However, there’s no display showing anything. It seems like the issue isn’t with the monitor since I connected it to another PC. I’m not sure what went wrong or how to troubleshoot it further.
There might be an issue with the connection. Did you confirm all links are set up properly?
This might involve several possibilities. Since this is your first build, review the fundamentals. Where did you connect your screen cable? It should go into the GPU, not the motherboard. Also, it's typical for a brand new PC to occasionally loop (restarting repeatedly without showing anything) if you haven't already reset it. Reconnect everything, press power and wait about five minutes without touching anything. Then, as Elliecat mentioned, verify all connections to ensure nothing is loose or missed. Also confirm the RAM is seated correctly—you should feel a slight click when installing them. If the PC still doesn’t power on, according to the PCPartPicker link in your profile, your CPU likely has an integrated GPU. Remove the GPU and plug the cable back into the motherboard so you can identify the issue. Once that’s done, things become more complicated. There may be a small LED on the motherboard indicating a problem. Look for a light blinking near the RAM or at the bottom of the board. If nothing appears visible, it’s possible you won’t find a solution easily and might need to take the computer to a repair shop.
The yellow indicator at the bottom remains on even after inserting the RAM, yet the system still doesn't respond.
It seems the CPU light is the problem. I didn’t realize how delicate it was—I accidentally touched two pins and it looked different afterward. I’m not sure if the pins are bent, but it looks like that caused the change. Honestly, I was assembling it on my bed since there wasn’t much space here.
It seems the main problem is likely the delicate pins on the motherboard, which can easily bend or break when the plastic casing is taken off. If you still have them, you might try using a needle to gently straighten them—just remember to unplug the computer and handle the CPU carefully to avoid further damage. When in doubt, it’s usually safer to replace the motherboard instead. Watching a tutorial can help you through the tricky steps, as this part is quite risky.
