Comp lags with excellent performance, why?

Question

Windows

In general, such a problem, there is a PC intel i7-10700k + gigabyte b460 hd3 + msi 1660 super + 16 gb ddr4 + 1tb ssd samsung 960 evo. However, the computer behaves strangely, the mouse almost constantly lags and sometimes only calms down, the PC itself also freezes often, in the first place I even mount fullhd, but even this is difficult for him, constantly freezing and so on. That is, it lags even on simple tasks, although the percentage is not used much and does not heat up, I can say the same about the video card. What could be the reason and what are the ways to check what is causing it?

Answer 1

What about the resource monitor for the CPU at the time of lags? How is it with the indicator "% of the maximum frequency"? The indicators for the line "system interrupts" are interesting. What does it mean: "it lags even on simple tasks, although the percentage is not used much and does not heat up, I can say the same about the video card"? What tasks are "easy"? Are there any lags without running operations in applications? Too much emptiness in the description of the problem. Here they tell fortunes on coffee grounds.

Answer 2

is the disk loaded with something? Maybe he downloads updates in batches ...
Are the drivers all right?
Wired mouse?

Answer 3

I would also take a closer look at the power supply.
And the motherboard also has stabilizers, the malfunction of which can also look chaotic.
And you can start everything by the elimination method, pull out all the connectors, remove all modules.
Leave the Processor, Memory and System Disk. Video use "Integrated".
And then gradually connecting the elements to reveal the "spoilt".

Answer 4

if a mouse lags in Windows, then in 98% of cases it is troubles with iron, and in the vast majority of cases - with a disk, look at the system logs in Windows, usually there are a lot of things piled up with such symptoms

Answer 5

I think so, or overheating of the processor. You need to see if the fan is spinning. Or the memory settings in the BIOS are not set correctly. Many Chinese planks have a high frequency. Or maybe a virus. In general, it's hard to say anything without seeing the computer itself live.
I forgot to say. If ssd plows continuously for more than a year, then 90% of it must be changed.

Answer 6

At the time of the screen, the music played through the Internet? like no. What do you have 5GB of RAM?

Answer 7

Fork out for a legal Windows. Again, probably, you have installed some kind of Beast and are suffering.

Answer 8

From what you wrote, one can only guess.

Answer 9

Mouse wireless, MS? So my computer lagged with the "mouse" with the set from MS, changed the mouse, and the lags were gone.
