USB inputs keep disconnecting

[killafruit]

Hello. For the past few days my USB inputs keep disconnecting from my pc after some hours of using them and the only way to reconnect them again is by restarting my pc. So everytime my inputs disconnect, i have to boot up my pc again.

 

I've tried searching for answers online but none of them really helped. I tried turning off the power saving mode thing, updating my drivers, and other solutions but it still can't solve my problem.

 

Whenever my inputs disconnect, the LED lights on my keyboard and mouse still light up (i use a coolermaster ms120 masterset) but they wont function. I'm not sure whether this is a software or hardware problem. I also tried changing the PSU because i heard that a damaged PSU can affect the USB inputs. Thank you :/
