Hello. The situation is completely incomprehensible to me.

Comp: i3-3220, 8GB RAM DDR3, Intel HD Graphics. Wired USB mouse, keyboard too.

Background:
There was a motherboard GA-B75-D3V.
When playing games, the mouse and keyboard suddenly stop working. Network and music while working. After a reboot, everything is ok - for the time being. Then again, after an indefinite time, the mouse and keyboard hang.

I thought that the chipset was heating up, but on the other hand, if the chipset failed, all the peripherals, both the network and the sound, would fall off. But the sound and the network work. The problem was observed only in Windows.

In Linux, I don’t run anything significant, everything is fine there, nothing fell off.

I bought a new motherboard GA-Z68P-DS3, I'm sitting on a discrete graphics.
I was playing a toy now - and bam, the mouse and keyboard hang again.
The LED on the mouse is on, the LED on the keyboard is on. But the keyboard does not respond to pressing the namlock.

I boot into Linux, I'm setting up Mikrotik with winbox. Nothing else from the software is running. And suddenly - bam. The same thing - the blade of the mouse with the keyboard, but the network and music work.

Has anyone had this happen? Or even what it could be?

Sensor temperatures are normal. Processor 35 deg., PCH diode (chipset) 44 deg.

From USB devices I have nothing else like that. But apparently it is USB that falls off, while maintaining power on the ports. Why?

I'll try to give a non-obvious answer, but nevertheless, which I met in practice, it may be the monitor, try testing with another monitor or reduce the brightness on the current

Talyan , 3-10 years is a good reason to revise or replace the PSU. So, a month ago I accidentally got into the BIOS, and there one voltage is much higher than the tolerance ... and it works ... but I replaced a couple of capacitors from sin. Moreover, one of them - did "swollen".
In standby mode, by the way, is USB powered?
