Long boot after installing Nvidia drivers

[LvStars]

Hi, I have a big problem with my older pc. I recently buy a new gpu card, because old one is dead and install windows 10, at first everything was working great until I turn it off and unplug it from power. After I turn it back on, there was very long boot time ~15-20 minutes, and even after it boots there is very high cpu usage and I can't do anything about it. So I boot windows in safe mode and downgrade display adapter drivers to Microsoft Basic Display Driver and turn off updates. Now it boots correctly and everything is normal, except lagging video, even lower quality movies, so that's not the solution to this problem. I have tried a lot off things and nothing helps, even tryed older windows like 7 & 8.1, but there is same booting problem after I install Nvidia drivers.

 

I hope someone can help me with this problem and sorry for my bad english

Do you have another computer you can try the video card on? Can you try the onboard video card only in your computer and see if it still has the issue? It might be a video card problem or a power supply problem.

All my other computers are laptops, so I can't try on other pc and I don't have onboard video, my motherboard is old and it don't support something like that. I don't think that there is a problem with video card, because everything works great until I turn my pc off and unplug it from power and my power supply is also new, 500w, so I don't think that's the problem either

Hmm try installing the drivers again? Might have just been a botched driver install?

I tryed that, but with no sucess. Also tryed older drivers, but that didn't help either

I haven't looked but has anyone else reported windows 10 problems with your cpu and motherboard? It might be obvious with video driver update.

I didn't find anything, i guess, that's because the motherboard and cpu are pretty old, 10 years maybe...
