Platform Power Management Capabilities:Supported Sleep States
Sleep states allow the computer to enter low-power modes after a period of inactivity. The S3 sleep state is the default sleep state for Windows platforms. The S3 sleep state consumes only enough power to preserve memory contents and allow the computer to resume working quickly. Very few platforms support the S1 or S2 Sleep states.
S1 Sleep Supported false
S2 Sleep Supported false
S3 Sleep Supported true
S4 Sleep Supported true

答え1
電源装置のストレステストを行う必要があります。
まず、電源装置から供給される電圧を監視する方法が必要です。ほとんどの場合、マザーボードの製造元が提供するユーティリティを見つけることができます。昔は、speedfan を使用していました。
では、何を探しているのでしょうか? + または - 5% を超える偏差です。12V レールでは 11.4V ～ 12.6V、5V レールでは 4.75V ～ 5.25V です。3.3V の場合も同じ原理です。
電源が仕様から大幅に外れている場合、コンピューターがほぼ瞬時にフリーズする可能性が高くなります。
モニターが起動したら、ファーマーク. GPU に負荷がかかります。10 分以上実行しても電圧が 5% 以下に下がらない場合は、問題ありません。
ここで、GPU と同時に CPU に負荷をかけるために、Prime95 のようなものを同時に実行する必要があります。
いずれかの電圧が定格電圧の 5% を下回る場合は、問題が発生している可能性があります。
