所以我的笔记本电脑屏幕一度空白,我不得不手动重启。笔记本电脑安装了 32 GB 的单个 DIMM。但自从重启以来,RAM 一直显示为 1.3 GB。memtest86
检测到 32 GB,在 RAM 中找不到任何错误。
我意识到这一点的原因是,笔记本电脑变得非常慢,甚至鼠标移动都变得不连贯和滞后,我在尝试诊断问题时发现了内存问题。我在尝试诊断问题时重启了几次,一次它确实切换回了 32 GB,但我不知道我做了什么才做到这一点。我束手无策,在购买新的 RAM DIMM 之前,我想看看我是否可以在这里尝试一些指示。以下是一些补充信息。

我拿到了memtest86
日志。但它太大了,无法添加,而且我不确定它是否包含某种不应该在互联网上发布的识别信息。因此,如果我可以在日志中 grep 任何具体内容,请告诉我,我可以将其添加到此处。
