PC is turning off...no clue on what to do next.
PLEASE HELP!! I am experiencing a recurring issue with my PC during gaming at 1440p resolution . After 30-40 minutes of use, the system encounters a critical failure. I have done nothing but research the last few days and feel like I'm getting no where. Any at-home experts out there would surely be appreciated, thanks! Here are the symptoms: Screen Goes Black : The display disconnects as if the computer has been turned off. Monitors display “No Signal” or enter standby mode. System Remains On : All case and component fans remain active. Fan speeds increase significantly and stay elevated until a forced shutdown is initiated by holding the power button. 1080p Gaming : Reducing the resolution to 1080p allows for slightly longer gaming sessions but still results in the same crash eventually. ECO Mode in BIOS : Attempted enabling ECO mode in the BIOS to limit power draw, but the issue persists under both 1440p and 1080p settings. Troubleshooting Steps Taken: Updated all drivers, including GPU (Adrenalin Edition) and chipset drivers. Ensured Windows 11 is fully up to date. Updated ASUS BIOS to the latest version. Performed stress tests (FurMark and Cinebench) to validate stability and thermal performance. Attempted reducing resolution (1080p) and enabling ECO mode to limit power draw. Observations: Thermals appear under control during benchmarks and gameplay (averages: GPU & CPU at MOST in the mid to high 60's°C). Power delivery may be a concern , as the issue predominantly occurs under GPU-intensive loads at higher resolutions. No other time does the PC shut off like that. The PSU ( Corsair RM750e ) is rated for 750W and should theoretically be sufficient for this build. Request for Assistance: I am seeking guidance on: Identifying whether the issue is related to power delivery , GPU hardware , or driver/software conflicts . Suggestions for additional troubleshooting steps or potential RMA recommendations for affected components. Insights on whether the PSU, GPU, or any other component might be the root cause based on the described behavior and benchmarks.

You may verify the system using another GPU but most cases point to a GPU-specific problem. A black screen display and increased GPU fan speed to maximum often signal driver issues or a failing VRAM. After updating the driver and reinstalling both the current and previous versions, if the problem continues it suggests the card's VRAM is defective. I've encountered this frequently in my work; it could be resolved by reinstalling the driver, replacing the card, or initiating an RMA. Occasionally, lowering the GPU clock speed brings stability, though this is usually a short-term solution that may deteriorate over time. If the card was recently bought and the issue persists, consider returning it for repair or replacement.
