我两周前安装了全新的 ubuntu 20.04，但从第一天起，操作系统在闲置一段时间后就挂起了。我该如何调试它？
- 已全面更新
- 双启动（Windows 10）运行良好，默认 grub 配置了一切
- 该操作系统取代了已经运行良好的两年前的 Ubuntu 18.04
- 我禁用了屏幕锁定，因为我认为它导致了我的问题（我锁定了电脑，5 分钟后电脑就冻结了）。但问题仍然存在
- 我附上了系统日志的一部分。我离开键盘大约 2 个小时，回来后系统就卡住了。但我在这个日志中找不到任何有用的信息。
- 硬件是台式机 ryzen 3 1200、8GB RAM、nvidia 980gtx、小型 SSD 和大部分未使用的 HDD。
以下是我的部分系统日志（cajueiro 是主机名）：

那是 Boinc，该软件用于通过利用我们的 CPU 和 GPU 处理一些工作负载来帮助科学项目。这些日志中一直有 Boinc 发出的错误消息。上周我卸载了它，我的电脑再也没有崩溃过。
我将尝试一些网格计算的替代方案。
