最近の修理品で下記のログが記録されていた。
エラーではなく警告だが、diskの警告が連続記録されている。
症状としては時々ハング状態になる。
例えば、マウスは問題なく動作するが、フォルダを開こうとすると反応がなく、ちょっと経ってから（1～2分程度？）いきなり開く。
但し、それ以外の違和感はない。
調べるとダンプが1個あり。
iaStorA.sysで不具合が発生しており、HDD交換後のテストであることを考えるとM/Bの可能性が高い。
誰かの参考になるかもしれないので下記記載しておく。

DRIVER_IRQL_NOT_LESS_OR_EQUAL (d1)
An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high. This is usually
caused by drivers using improper addresses.
If kernel debugger is available get stack backtrace.
Arguments:
Arg1: 0000000000000003, memory referenced
Arg2: 0000000000000002, IRQL
Arg3: 0000000000000000, value 0 = read operation, 1 = write operation
Arg4: fffff88001502a9b, address which referenced memory
