Sudden fps drop and audio cuts off

[MasterPc]

Hello,
Everything was fine and i was getting constant 110-144fps on games without any single problem and yesterday after i installed farcry 5 and was playing it after 3-4 hours the game started to give me lag spikes and audio cut offs for 1-2 second and then were fixed again and it grow worst every more minute i played the amount of lag spike/audio cut off became more. i thought its farcry5's problem and restarted my pc but i had this problem now on all games rainbow six siege , pubg and ... . and even my windows experience got lagy and isn't smooth as it was before. i reinstalled graphics driver using DDU and installed latest version , restarted pc several times even shut it down for hours and still the same problem "after 20 minutes of playing i start to get sudden lag spike/fps drops with my audio cut off for about 1-2 seconds.
i didnt had this problem at all till yesterday on this windows.
i started having this problem on my previous windows and i reinstalled and it got fix until now.
what would it be from ? cpu temp and usage is like 80 temp and 100% usage in games but it was like this all the time and didnt have the problem. it is from my ssd ?
Please help me thx.

I'd first ask you to make sure you're on the latest BIOS update.
Then try and make sure your on the latest drivers for your GPU and chipset.
Then you can rule out a corrupt OS by running a repair install.

FYI, on your build, you should've gone for a DDR4-3200MHz kit.

i tried all the above and nothing changed have to reinstall my windows anyway.
aside from this problem does 6600k bottleneck my 1080ti ? or does my 2400mhz ram bottleneck my gpu performance ? my cpu is at 100% always in rainbow six siege playing on max out 1080p ultra settings.
does it mean if i get a 16 gb 3200-3000 mhz ram and 8700k - 7700k i get more out of my gpu ? thx !

i think the simpler advice is to get more RAM.
8gb isn't cutting it anymore.
next thing is GPU temp, pascal GPU starts to throttle down a bit at 70C, and a lot more at 80C.

Nah i dont get more than 68 degrees on 100% load at all.
Though my cpu is 85 degree on full load should i pick a decent air cooler ? How much would it make diffrence ?

if temps, using good CPU coolers would push down the max temp to 65-75C
if performance, there should be no significant improvement gained unless the previous temps gave you stutters(sign of an aging/failing cpu). intel cpu threshold is usually at 90-95C, keeping it much safer at 15-25C lower than the limit is going to make your CPU last much much longer before it fails and starts giving problems.
