Problem with drawing the image on the monitor, what should I do?

Question

Batteries

Hello. I have such a problem, after rearranging Windows, the image on the monitor is jerky, and the frames are blurry. I installed windows 7, installed drivers from the site and driver Pak. Now I installed Windows 10, drivers through Windows Update, and tried the Pak driver, and from the site's site .. I tried to install another video card. Tried another monitor through an hdmi TV. In AMD, the catalyst tried everything. He called the master, he didn’t understand .. He says maybe there is not enough power for the processor, the 8pin connector is inserted 4pin, but this should be enough intel core i5 4x 3100. Yes, and before installation it was normal.m / board: JW-PH67A, video card radeon 6850, ssd240gb, 8gb RAM 1333. I don’t think about food, I used to have an hdd and a floppy drive, and I was drawn. Somehow I installed it a long time ago, it seems there was such a problem, I don’t remember how I solved it, but now for a week I don’t know what to do .. I already smeared the chipsets with paste, I cleaned everything .. We tried double and triple buffering. And they launched Windu from a flash drive, the same thing. And the disk with the other Windows is also jerky .. As if the standard settings do not suit him, or the BIOS is unlikely. In the BIOS, achi mode ..
I don't know what to do with it now.

Answer 1

Some motherboards that use an 8-pin CPU power connector must have power on all pins of the connector to work properly, while most motherboards of this type can work even if you use only one 4-pin power connector. )

Answer 2

Such friezes may be due to the reduced frequency of the processor (throttling).
In the BIOS or in the power settings, what is the processor cooling mode, active, passive?
Reset bios to default anyway, even if there is nothing similar there, and in Windows try the throttling stop program, it will show you both the current frequency and the temperature conditions for throttling (if the reason is in it, of course) will show.

Answer 3

And if you check the visible map on another system?

Answer 4

Oh well, it seems that just the wrong video drivers are worth it. What port is your monitor plugged into? Video card or motherboard? If it is on the motherboard, then the Intel HD3000 video subsystem is involved, on which the drivers should be installed.

Answer 5

And why does Windows Update and the Pak driver then install everything except this driver
