Like I have pretty good knowlage about pc's but this rally confuses me when i first got my pc obviously like the other is was fresh and new - (i bulit it myself- i dont like pre bulit pc's) and after few months now - my pc is almost year old i started noticing that it started lagging and became SLOW - like it actualy drives me crazy - applications open lot longer - internet/ normal apps/games/folders, games started lagging - they never laged before for example League of legends before didnt lag and i was getting over 230 fps on max details - now it lags like every minute or two and fps is just around 180 so i dont rally understand - does electronics when they get older get slower or is it just myth? also boot time is around 10 seconds longer and takes it like 5 sec before i can start typing my password - i tryed like everything i checked for viruses, malware, adware, i use ccleaner, cleaned cache from temp/%TEMP% and prefetch folders, used command "tree", i used that trick in regedit i used almost everything and still didnt work

spec: Intel Pentium G4500 3.5 GHz | Nvidia GeForce GTX 1050 ti | 4 Gb DDR4 2400HHz RAM | 1Tb HDD - half full | MSI H110M PRO - D motherboard | 300W Power Supply (my PSU is good i checked it) | Windows 10

- also i forgot to mension that my ram on basic is 57% full but when i open game its over 80% - even in league of legends... (it requires 2Gb for Windows Vista and newer)
-and system sometimes uses disc to 90% when i play games or when its just on desktop

Please help me guys i don't know what should i do - i dont rally like re-installing Windows cause i have like over 100 Gb data that i dont like wiping out and i dont have storage to put is somewhere so i could get it back..... 🙁

Tkanks
