i encountered an issue with my pc while playing games such as bf 2042, bf 1 and modern warfare. the problem is that movement becomes unstable when I press keys quickly after another; the movement goes out of control, causing me to walk left while the player advances, or I experience lag so severe that I can't move left even when I try. the mouse gets stuck in ads, and moving or aiming to a target just gets frozen until I shift it to the opposite side, which then works again. this happens intermittently rather than consistently. i have tested all possible solutions—checked usb ports, used a different usb, upgraded ram, and even replaced the cpu because it was near its limit. my system specs are: mainboard asus prime z270k, processor intel 7700k, ram gskill ripsaw 3200hz 16-18-18-36, drives 870 evo samsung ssd sata, corsair mb 600 pcie ssd.

my system ...
mainboard: asus primez270k
cpu : intel 7700k
ram: gskill ripsaw 3200 mhz 16 18 18 36
graphic: nvidia 1070 ti gigabyte gaming edition
drives:
ssd samsung 870 evo sata version
corsair mp600 pcie 3.0/4.0
an old hdd with 1. tb
in multible games i like bf 2042, bf 1 modernwarfare 2019 i have the problem that my input is out of control sometimes i push a key and it doesn’t even register. then sometimes i move left by pressing the left button, then right, but the player keeps moving left. When i follow an enemy in ads the mouse sometimes gets stuck and i can’t move it like it’s blocked or something. that happens not often but it does occur occasionally. i checked everything from usb by a tester to the cpu. almost every benchmark tool checked, including the burn-in test and other microsoft tests, didn’t find anything. could it be that my internet provider is the issue? but i don’t see input lag or packet loss symbols in bf 1 and 2042 in mw. I often have moments where packet loss goes from 15 to 20%, but that’s random and only happens during the match I’m playing in, while the next one is fine. maybe something I did a few years ago—like changing something on the pc while it was working and hitting the psu plug—caused a lightning to come out, but everything worked afterward except my dlano, which was up at the time. I ended up buying a new psu. It might be the reason, but i’m not sure.

Are there any heavy processes running in the background?
Is your antivirus too strict?
Do you have older spinning hard drives, such as a 1TB HDD, that could be causing delays?
Are your games stored exclusively on SSDs, or are they also on HDDs?

There are no programs running except Nvidia control panel and a few gaming launchers at startup. All games are played on an SSD. The HDD wasn’t the cause of lag. I switched RAM from 2133 MHz 2x8GB to 3200 MHz 2x16GB, but experienced some issues before. I’m unsure if this might affect input lag since the system now has stable frame times. I haven’t changed the RAM again. I also observed unusual mouse behavior when moving the 3x power supply connector about a meter away (word not in English). I don’t have any antivirus software installed; I only have Windows Defender.

GPU?
PSU: specifications, make, model, wattage, condition? Heavy usage for gaming, video editing, or crypto-mining?
My first concern is whether the power supply might struggle under maximum load.
Check the Task Manager and Resource Monitor (use each once, one at a time) to see how the system performs.
Launch the appropriate tool window, wait for stabilization, then move the observation window to one side.
Play a game and watch the changes: resource consumption percentages and which components are active.
Avoid hasty judgments; test with different games and conditions to spot a consistent pattern related to mouse/keyboard use.
Keep exploring to gather more details about the issue.

it's an rm 650x from corsair.
the only thing consuming all his resources is the processor during games.
his load stays at 80–100% in games; bf5 has nearly 100% usage, around 85–100%.
modern warpware helps when playing groundwar because it boosts performance.
my GPU reaches 95–100% usage constantly, but my CPU is now hotter than before—reaching about 70–80°C.
before, RAM was around 32k, now it's about 10k to 15k, which shouldn’t be a problem.
I reset my dsl modem today and it seems better, though I don’t think that fixed the mouse blocking issue.
Earlier, I tried plugging in something via USB and hitting the PSU plug—it caused a loud noise, but everything was fine then.
Now DLAN works well again after the purchase.

That Corsair RM650X is two years old or older and has experienced significant gaming use—correct?
Keep in mind that PSUs offer three voltage outputs (3, 5, and 12) for various system parts. An issue with any of these voltages can lead to a range of system malfunctions.
Do you have access to another functioning PSU that you could replace?
Or do you have a multimeter and know how to operate it? Or perhaps someone does?
FYI:

Any voltage deviations outside the acceptable range make the PSU highly questionable.

Don't know how to check this if it works well but I think it should bought it half year ago... Changed the ram and the delay is gone but there is some issue with changing ram on this board... It just don't start normally after changing ram I become black screen without bios and after 3 or 4 restart atemt it loads some secure bios which I can enter with f 1 after that the ram and the PC is working but this happens every time I change ram and don't think that is well for the bios or Mainboard musst be some failure but this was also as I build the pc first
