Essentially what is mentioned is that nvflash.exe appears to be a tool for updating GPU BIOS. Perhaps my understanding is incorrect. I’m not particularly skilled at overclocking, although I do experiment with voltage adjustments. My usual approach is to avoid changing the power settings, and I haven’t modified the GPU BIOS beyond using the “Save BIOS” option in GPU-Z to reset drivers when my card was inactive in low-power mode; I also never enabled saving it.
A bit about how I use my system:
- CPU: Overclocked to 44x with FLCK at 1GHz, leaving all other settings at auto, including uncore, and keeping voltage settings unchanged. Once stability was confirmed, I reactivated C1E, C3, Package C0-C1, and EIST.
- DDR: Overclocked using Profile 1 XMP on my Gigabyte Z170-UD3, running at 3200MHz with 16-16-16-36 timings.
- GPU: GTX 960 overclocked by +120MHz Core and +600 Memory. It also proved stable without further voltage changes.
My problem
- I was browsing the internet, switching between Fallout 4 and other games, when I noticed all four threads were unusually strained (35-80% usage) even though no apps were running. I suspected nvflash.exe as the cause, so I searched online briefly before deciding to restart my PC. After rebooting, I was told there was a BIOS-related boot failure and offered to load optimized defaults. I considered it might be another issue (though I’m not sure), so I lowered my core multi by a few points and did the same for GPU and VRAM once I logged back into Windows. Since then, I haven’t experienced any problems—but I still feel something unusual is happening behind the scenes.
Tools I’ve used
- MSI Afterburner, Gigabyte’s F6 BIOS utilities
Monitoring tools:
- MSI Afterburner, MS Task Manager, CPUID HW-Monitor, and occasionally GPU-Z.
System specifications:
- CPU: Intel I-5 6600K @ 3.5-3.9GHz (4.4GHz overclocked)
- GPU: EVGA GTX 960 SC 4GB
- RAM: G-Skill RipJaw Series V DDR4 3200MHz (16-16-16-36, 4GBx2 in dual channel)
- HDD: Samsung 500GB 7200RPM SATA
- PSU: Corsair TX650W
- OS: Windows 10 x64
I’m not sure if I’m in the right forum community with this issue, but I’m hoping to find some comfort. If anyone has any advice, I’d really appreciate it. Thank you ahead of time!
NVFlash is intended for video BIOS, not system BIOS—it's just a coincidence it was the program you last closed. I'm not sure it did anything significant. What actually happened was your system likely wasn't fully stable, which caused the error when you restarted.

What actually happened was that your system might not have been fully stable, which caused the error when you rebooted. I thought the two were unrelated. Thanks for the reply. Do you know why nvflash.exe started using my CPU so heavily? There aren't many background apps that could stress that Skylake chip on all four threads like it did. That's what caught my attention.
