Troubleshooting PC Nightmares: A Cautionary Tale of Overclocking Woes

If you’ve ever experienced the nightmare of a malfunctioning PC, you’re not alone. Recently, I faced a dilemma that left me seeking help from the proverbial “Reddit gods.” After investing my hard-earned savings into a prebuilt gaming tower, I found myself in a frustrating situation that has me scratching my head.

My Setup:
Processor: Intel i5 9600k
Graphics Card: GTX 1080
Motherboard: ASRock Z390 Extreme
Memory: 16GB DDR4 RAM
Storage: SSD/HDD combo

For a solid two months, this rig ran without a hitch. It was a dream come true, particularly as I geared up for streaming. However, in a moment of overconfidence, I decided to indulge in overclocking my CPU. Initially, this decision seemed to pay off; Task Manager reported a stable 4.88GHz overclock that maintained good temperatures and performance.

But then the troubles began. After relocating my tower upstairs, I started experiencing random Blue Screen of Death (BSOD) events, specifically the “WHEA UNCORRECTABLE ERROR” (with an error code around 0x124b). These crashes could occur while idle or during gaming sessions, significantly derailing my plans.

To troubleshoot, I ran a series of stress tests, focusing on the CPU and RAM, which passed without issues. I even attempted to revert my overclock settings within the UEFI, but to my surprise, the system continued to run at the previous overclocked state, despite loading the default settings.

In my quest for resolution, I even performed a clean installation of Windows to eliminate any software conflicts that might contribute to the BSODs. Unfortunately, this proved fruitless, as the problem persisted.

I’m not completely inexperienced with PCs, but I feel baffled and unsure about what steps to take next. The thought of potentially damaging my CPU is unsettling, yet I doubt this is the source of the issue. Moreover, the GPU seems to be functioning well, so I’m considering running a check disk on both my SSD and HDD to eliminate storage concerns.

As I continue to navigate this troubleshooting journey, my hope is to find a solution that allows me to fully enjoy my gaming and streaming setup again, rather than being plagued by persistent blue screens. If anyone has insight or similar

  1. It sounds like you’re experiencing common issues related to CPU overclocking and system stability. Since you mentioned that reverting BIOS Settings hasn’t taken effect and the system still runs at overclocked speeds, I recommend checking the following:

    • Clear CMOS: Reset your motherboard BIOS to default settings by clearing the CMOS. This can be done by removing the CMOS battery for a few minutes or using the clear CMOS jumper, as specified in your motherboard manual.
    • Verify BIOS Settings: After resetting, ensure that all overclocking settings are completely disabled and that the system is running at default clock speeds.
    • Stability Testing: Use tools like Prime95 or AIDA64 to stress-test your CPU at stock settings. Monitor temperatures closely to ensure they stay within safe limits.
    • Check for Hardware Issues: Since you moved the tower upstairs, verify that all components are properly seated and that your power supply is adequate for the overclocked system. Run MemTest86 to check RAM for errors and chkdsk on your storage drives to rule out disk issues.
    • Update BIOS: Ensure your motherboard BIOS is updated to the latest version. Sometimes, BIOS updates can fix bugs related to overclocking and system stability.
