When I play games like Rust or CS, which I’ve been playing for 5 years on my 5-year-old computer, or even randomly, the screen goes black. When the black screen happens, I can still hear the sounds from the open applications for a short time. On the screen, I see the monitor’s “HDMI2” message, which, as you know, is shown when there is no image coming from the HDMI cable (this happens on TVs as well) to indicate which channel your monitor is on. In short, no image is displayed.
Yes, I’ve updated every hardware and software you can think of.
The RAM is being detected, I’ve reseated them, cleaned everything, and checked all the cables.
You might say, “Check the 4 indicator lights on the back of the motherboard to identify the issue,” but due to my case design, I can’t see those lights. There is an orange light, though, yes. However, regardless of which light turns on, I’ve already checked everything right before the black screen happens, and there’s no issue with the RAM, GPU, or CPU. I even opened and inspected the power supply myself (I’m an engineer), and there was no visible damage to the electronic components—everything was clean, no dust, nothing.
For those who might suggest the power supply is insufficient, I’ve been using a 750W PSU for years, which is enough for this system. As I said, this issue doesn’t happen randomly but occurs either when I launch applications I’ve used for years or about half an hour after launching them.
My SSD and HDD are clean.
You might think it’s due to overheating, but it’s not. The temperatures of the CPU, GPU, and RAM are all within normal ranges when this issue occurs. I’ve watched every possible video from Indian YouTubers and tried everything. It seems that people on foreign forums haven’t found a solution either. Some tried replacing the power supply, but it didn’t work.
As a clue, I removed the CMOS battery, which stores BIOS and UEFI settings, from the motherboard and disassembled the computer parts. (A fellow Indian YouTuber said the issue was BIOS-related and that resetting the BIOS this way would fix it.) After putting everything back together half an hour later, the BIOS was indeed reset, and the computer ran without any issues for a whole day. Later, when the issue occurred again, I tried running the system without the battery, and interestingly, it worked for another day without errors. However, the problems started again after that. I replaced the battery, but it didn’t help.
So, in my opinion, this is a BIOS-related issue. Something happens under load.
Let me mention the OCCT test results: It passes the CPU+RAM, CPU, MEMORY, VRAM, and POWER tests (before the BIOS reset, it even failed the power test). But as soon as I start the two 3D STANDARD tests, the black screen greets me before the 1st second even passes.
That’s the situation. If there’s a detective out there who can solve or has any ideas, I’m all ears. May God be with you, folks. I hope I haven’t forgotten anything. Feel free to ask questions, and thanks in advance to anyone who puts thought into this.
