Blue Screen Boot Loop: Data Rescued First, Then a Clean Reinstall
电脑蓝屏死循环：先抢救数据，再干净重装系统

A USYD postgrad's desktop suddenly dropped into a blue-screen loop — restart, blue screen, restart again, never reaching Windows. The panic wasn't the machine; it was the thesis work and files still trapped on the drive. The message came in late at night; the on-site visit was booked for first thing next morning in Zetland.
悉尼USYD一位研究生的台式主机突然陷入蓝屏死循环——重启、蓝屏、再重启，怎么都进不去Windows。真正让人慌的不是电脑本身，而是硬盘里还没导出的论文资料和重要文件。晚上收到求助，第二天一早就约在Zetland上门处理。
The reflex that loses your data
最容易丢数据的第一反应
When a PC won't boot, most people reach straight for "reinstall Windows." On a machine with data you still need, that's the single riskiest move you can make — a reinstall can overwrite exactly the files you were trying to save. The right sequence is the opposite: get the data out safely before touching the system.
电脑进不去系统时，很多人第一反应就是"重装系统"。但如果里面还有你需要的数据，这恰恰是最危险的一步——重装很可能正好覆盖掉你想救的文件。正确的顺序刚好相反：先把数据安全导出，再动系统。
The right order of operations
正确的操作顺序
- Data first. Before anything else, every important file was located, pulled off the drive and backed up to a safe copy. Data is a student's lifeline — it comes out before the system goes in.
- Clean reinstall. With the data secured, a fresh, clean Windows install to clear whatever had corrupted the boot.
- Drivers fully tuned. BIOS settings, the graphics-card driver, and every essential program installed and configured on-site to a stable, optimal state — not left half-done.
Met the student in Zetland and had the machine back up and running the same visit.
- 数据优先。动系统之前，先把所有重要文件逐一找出、从硬盘导出并备份到安全副本。数据就是留学生的命——先把它救出来，再装系统。
- 干净重装。数据落袋为安后，重新做一次干净的Windows安装，清掉导致无法启动的问题。
- 驱动全部调优。BIOS设置、显卡驱动、各种必要程序，全部现场安装并调试到稳定、最优状态——不留半成品。
就约在Zetland当面处理，当次上门电脑就恢复正常使用。
A bonus we couldn't leave alone
顺手解决的一个附加问题
While speed-testing the rebuilt machine, the room WiFi was crawling at about 20 Mbps — a waste on hardware this capable. A quick network tune-up brought it up to 90+ Mbps, so the reinstalled PC actually got the connection it deserved.
给重装好的电脑测网速时发现，房间WiFi只有可怜的20Mbps，这么好的配置简直暴殄天物。顺手做了一次网络优化，把网速提到90Mbps+，让这台刚装好的电脑配上应有的网速。
Result最终结果
Data recovered and backed up in full, a clean stable Windows install with every driver tuned — and room WiFi lifted from 20 to 90+ Mbps. All in a single Zetland visit.
数据完整找回并备份，系统干净重装、驱动全部调好，房间网速从20M提升到90M+——一次上门全部搞定。
