PC not showing display
PC not showing display
I'm having trouble understanding what's happening with my PC lately, but its behavior has become very unpredictable. Sometimes nothing appears, like no BIOS or anything, even after swapping the HDMI cable from the GPU to the motherboard. After a few manual restarts, the screen will show content again, but when I use the PC, it will suddenly go blank after about 10 minutes. It also stays blank during sleep mode and won't wake up. One change I noticed is that the fan became much louder recently, but I'm not sure how to figure out what's causing that. Thanks in advance.
Check Reliability History/Monitor and Event Viewer for any errors or warnings around the time of the issues. Frequent or changing errors could indicate a failing or aging power supply unit. The Antec PSU might be reaching the end of its lifespan.

Turn off the system, unplug it, and open the case.
Remove dust and debris from inside.
Ensure all connections, cards, RAM, jumpers, and case parts are securely installed.
Look for any signs of damage.
If the issues persist, replace it with another functioning 500-watt PSU or higher.
Welcome to the forums, newcomer!
When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.
Thanks, will share now.
CPU: Intel Core i7-9700K
CPU Cooler: Cooler Master Hyper 212 LED CPU Cooler
Motherboard: MSI B360M Bazooka LGA 8thGen. Can't verify BIOS version since monitors won't turn on, will fix this if possible
RAM: 32GB DDR4 2666Mhz
SSD/NVME: Samsung evo 1tb nvme, likely Samsung 500 GB, details unclear but should match a 500 GB SSD
GPU: RX 5700 XT 8GB GDDR6 Gaming GPU
PSU: Antec VP500 80+ High performance PSU, five years old
Chassis: Evetech trio tempered glass RGB gaming case
OS: NVMe running NixOS and SSD running Fedora, also a 750 GB drive with Windows partition formatting
Monitor: Iilama and Dell

If problems persist, replace with another functioning 500-watt PSU and use only the provided cables.
Also, consider adding a new CMOS battery following the motherboard's instructions.
At the moment, I can't afford a new PSU, but I've removed the GPU and am using IGD, which fixed the problem. It seems there wasn't enough power being delivered. All connections are secure, and cleaning dust didn't help. Thanks for your support; it looks like the issue is likely with the hardware itself.
It might also indicate an issue with your GPU. If you have access to a functional PSU, testing with your GPU could help determine if the problem lies there. This way, you can identify the root cause.
It would have been wise to revisit this, removing the CMOS, turning on the power a few times, re-energizing the CMOS a few times, and then puggling resolved the problem.
