Question: No signal on monitor after reboot (no problems with monitor or cable)
Question: No signal on monitor after reboot (no problems with monitor or cable)
Hi!
I recently installed a new desktop PC for my son, and everything functioned perfectly after setup and cable connections. However, after a reboot, it stopped sending signals to the monitor via HDMI. I've tried various troubleshooting steps: connecting another PC to the monitor (it works), switching to a different HDMI cable (no signal), linking the HDMI to other GPU ports (no signal), connecting directly to the motherboard HDMI to bypass the GPU (still no signal), reseating RAM and GPU, removing the GPU, and even trying a different GPU. After resetting the BIOS by removing the motherboard battery, it worked initially. But once I rebooted into Windows, the GPU fans stopped working (though the HDMI cable was still connected to the GPU). I haven’t confirmed this behavior but have heard rumors about certain settings that might control fan speed based on temperature. I’m also checking if the PC has any error codes during startup. The build details are as follows: motherboard Asus Prime Z270-P, 8GB 2400Mhz RAM, Intel Core i5-7600 3.5GHz CPU, Nvidia GeForce GTX 1060 6GB GPU, 466GB SSD, Windows 10 Home OS, 650W PSU. I’ve listened carefully to the motherboard for error messages but found none. After temporarily fixing the problem by removing the battery and rebooting, it booted into BIOS without issues, but when I tried to open Windows, the connection failed. Could you help identify what might be causing this issue? If possible, any additional information would be greatly appreciated.
I've just purchased a new desktop PC for my son, a custom build.
The machine was previously second-hand with 16GB RAM.
I plan to reinstall the operating system to ensure there are no remnants from the previous seller.
Motherboard: Asus Prime Z270-P
Since you can access the BIOS after clearing the CMOS, what BIOS version are you currently running on your motherboard?
RAM: 8GB at 2400Mhz
Please take a photo of the RAM stick's label information and share it here. You'll need to upload it to a platform like Imgur. If using Google Drive, set it to public access.
How is the processor being cooled?
Power Supply: 650W
650W is the stated power rating for the system. Could you tell me the make, model, and age of your PSU?
At the moment I'm unable to boot into windows at all, the screen remain black and trying to find a signal. So it seems the restting CMOS trick doesn't work anymore.
Here's the link to the images i could provide and som from the boot up into bios:

If you visit this site;
PRIME Z270-P - Support
www.asus.com
you'll notice BIOS version 0808 isn't listed on their support page, suggesting it might have been removed because of stability problems or replaced by a newer version. I recommend updating the BIOS to 0812 and checking if that improves your setup.
Regarding RAM, it seems it was sourced from a Lenovo prebuilt unit and integrated into your system. According to the motherboard manual,
https://dlcdnta.asus.com/pub/ASUS/m...Ex...1762081709&Key-Pair-Id=K2ITB7O97XKKCX
page 1-7, when using a single stick of RAM, place it in slot A2. Your existing RAM can be upgraded to DDR4-3200MHz, but you'll need to enable X.M.P in the BIOS. Ideally, use a dual-channel RAM kit to maximize performance. Also, in 2025, aim for at least 32GB of RAM rather than 8GB.
Corsair CX650M isn't recommended as a PSU.
I hope you managed to assemble the build at a reasonable cost, since it appears to be made from components that others didn't prefer.
For the next steps, I suggest installing the OS onto the single SSD using offline mode, formatting it, and then manually installing all necessary drivers with the latest versions through an elevated command.
Please try your ideas, they seem quite affordable given the components (around 140-150 dollars).
I’m looking for a PC that can handle the games my son plays while also giving us space to learn troubleshooting and hardware upgrades together.
I’ll let you know if I manage to get it running or if I need more advice.
I believe I might have another PSU from an old build with at least 650W.
We’re planning to upgrade the RAM for this project, hoping to find good deals during Black Week.
Updated the BIOS to version 0812 and repositioned the RAM to A2 position following the manual, but encountered no success. Concerning XMP, enabling it isn't visible at all—though it appears in EZ mode with "disabled" selected, the option to turn it on isn't present. I searched online without success to find another method. It seems the RAM doesn't support XMP. No attempts made with a different power supply yet.
