First of all, I'm sorry if I can't explain the issue properly, English isn't my first language. So, there's a really cheap GTX 1050 Ti low profile from Gigabyte listed on my local sales site. The seller states that the GPU is basically not working at all, no fan spin and no signal at all and that he thinks he fried the card when he was trying to reassemble it after cleaning and plugged in the fan connector in a reversed way. Can such a thing fry the entire GPU or can this be fixed somehow because the GPU is really cheap, around $25 USD.

I guess I figured it out, it was the latest NVIDIA driver 430.39, went back to 425.31 and the issue seems to be fixed for now.

I already tried EIST and varios sleep states on and off, no difference, power mode is balanced and I checked the minimum cpu state is at 5%, the ram has no settings in bios and I never overclocked anything since there's no option for that in bios. The cpu is not even at 100% usage, it sits at 30% with 3.55 GHz which is the Turbo Boost frequency. If it was a virus, the restart wouldn't fix it. The only thing to try now is refresh Windows (it's 8.1 x64), boot linux from usb like you said or just do a reinstall if everything else fails.

System: Dell Optiplex 3010 SFF, CPU Core i5 3470 3.2 GHz, 8GB DDR3 RAM, 250GB HDD, GPU NVIDIA GT 1030 Issue: on first boot CPU is stuck in Turbo Boost mode (3.55 GHz) when idle, one restart fixes it and the CPU idles at 1.55 GHz. How it came to be: either bios update and loading default settings (less likely), or running Dell SupportAssist software where Tune performance default option messed with system files and registry. (more likely). Tried: loading system defaults on the newest bios, flashing the previous version of bios and loading system defaults, clearing cmos, enabling/disabling Turbo Boost in bios, enabling/disabling Speedstep in bios, switching back and forth from balanced and high performance power mode, running Dell SupportAssist again, uninstalling Dell SupportAssist. Opinion: Dell SupportAssist software messed with registry and system files since even disabling Turbo Boost in bios has no effect but one restart fixes the issue. Suggestions?
