The incident unfolded as follows: during a game session, the display turned black abruptly, showing an error like "HDMI input invalid/disconnected." For a brief moment, all active applications remained audible, but then the screen went dark entirely. Once the screen disappeared, I retained control of the computer, and it never stopped or restarted. This issue began about a year ago and has intensified recently.

I own a GTX 970 graphics card. If I keep both memory and base clock speeds unchanged, the system will consistently experience this crash during light usage. The unusual aspect is that when the card idles, it doesn’t crash; however, under heavy load (over 80% usage or stress testing), it does fail. Interestingly, under light activity—such as idle or 50-60% utilization—it remains stable. Running Prime95 and FurMark simultaneously for a short time didn’t trigger any crashes. Despite this, other stress tests suggest the power supply, motherboard, CPU, and RAM are functioning properly. The root cause remains unclear. I’ve also experimented with adjusting power limits, but only underclocking resolved the problem.

Applications known to frequently crash include VALORANT, Yuzu/Ryujinx (any game can fail), and Vanguard was not installed during emulator testing—it wasn’t Vanguard.

Side note: I previously faced issues with the GPU’s auto-fan controls, which were resolved after a BIOS update. That fix didn’t address the crashing problem, indicating it might be unrelated to BIOS settings.

If you have any additional test tools beyond those listed, please share them.

MBO: Machinist RS9
CPU: Xeon E5-1650 v4
RAM: 24gb DDR4-BUFFERED-ECC
PSU: Corsair RM550x, used, 6 years, excellent condition.
OS: Windows 10 22h2
Hardware: Two 1tb 7200rpm HDs, one 240gb SSD.
Network: Wireless with PCI-e card.

Update your post with complete hardware details and operating system information. Provide the power supply specifications, including voltage, amperage, age, and condition (original, build, refurbished, used). List the disk drive specifications such as make, model, and capacity, along with current usage. Include a description of all connected peripherals. Specify whether the network connection is wired or wireless.
