So I have this computer I have assembled for someone, When it hits 16+ MB/s is hits 100% and it can still go up to 120+ MB/s when benchmarking the disk, but when using it normally the pc tends to crash with blue screen sometimes, it worked fine the 1st week and then it began to have this problem, I have tried with 2 different hard drives where one of them works fine on another computer but in this computer it also hit high disk usage, I have also replaced the SATA cable with another and that did not help either, I have tried disabling the different services that can cause problems but that didn't fix it either, it has also been reinstalled 2 times and no luck there either, so I am totally lost what to do and hope someone can help me. Down below is a list of all the items in the computer.
