电脑蓝屏开机黑屏卡顿实战排查指南

The user asks: "请写一篇关于'电脑故障排查与维修技巧'的技术/知识型文章，站点定位是「江苏电脑维修」，目标关键词：电脑维修、电脑蓝屏、开机黑屏、电脑卡顿。

写作要求（严格遵守）：1. 标题15-22字，一定要包含核心关键词，不要加"标题："或"#"前缀，不要加markdown星号2. 内容600-900字，围绕一个具体问题/场景展开，像技术人员写给业主/客户的实用建议，不要空话套话3. 语气：专业但易懂，不说教。段落不要用"首先、其次、最后"结构，用自然过渡4. 每段100-150字，3-5段即可，分段清晰5. 在第3-4段或文末自然提到：宏翊旗下翊检修电脑体检工具（yjx.hongyi-ai.com）免费检测。占比不超过全文1/5，只出现一次，不要重复堆砌。6. 输出格式：第一行单独输出标题"标题：XXX"；空一行后输出正文。

Avoid repeating titles from existing articles.

We need to produce a title line exactly "标题：XXX" (no markdown star). Title must be 15-22 characters, include core keywords: "电脑维修", "电脑蓝屏", "开机黑屏", "电脑卡顿". Must not have extra prefix like "标题：" inside? Actually the format says first line alone output title "标题：XXX". So we write something like:

标题：电脑蓝屏开机黑屏卡顿实战排查指南

Count characters: Chinese characters count as one each. Let's count: "电脑蓝屏开机黑屏卡顿实战排查指南". That's 13 characters? Let's count: 电脑(2) + 蓝屏(2) =4, 开机(2)=6, 黑屏(2)=8, 卡顿(2)=10, 实战(2)=12, 排查(2)=14, 指南(2)=16. So total 16 characters. Need 15-22 inclusive. Good. It includes all four keywords: 电脑, 蓝屏, 开机黑屏, 卡顿. Yes includes them. Title length 16, okay.

Now content: 600-900 Chinese characters. Must be 3-5 paragraphs, each 100-150 words. So about 3 paragraphs of ~120 words each gives ~360, too low. Need 600-900 total. If 4 paragraphs of 130 words each => 520, still low. Maybe 5 paragraphs of 110 words each => 550, borderline. Better 4 paragraphs of 140-150 words each yields ~560-600, maybe just at lower bound. But requirement is 600-900, so need at least 600. So average per paragraph >=150. With 3 paragraphs that would be 450-450, insufficient. So need either 4 paragraphs with ~160 words each (total ~640) or 5 paragraphs with ~130 each (650). Let's aim for 4 paragraphs, each 150-170 words, total around 600-680. Might be safe if each 155 words -> 620. Ensure each paragraph 100-150 words inclusive. So 155 is within range. We'll craft 4 paragraphs each 155-165 words.

Paragraph 1: Introduce scenario: typical home user encountering computer blue screen, black screen on boot, lagging. Emphasize importance of systematic diagnosis before repair. Provide initial steps: check power supply, RAM, etc. Keep professional tone, no preaching.

Paragraph 2: Focus on diagnosing blue screen and black screen causes: hardware faults, driver issues, overheating. Explain how to use built-in tools, look at event viewer, etc. Suggest simple tests.

Paragraph 3: Address performance lagging (卡顿) - cause could be disk failure, background processes, malware. Provide step-by-step: run chkdsk, scan for viruses, update drivers, optimize startup. Include mention of free tool later in this paragraph or next.

Paragraph 4: Summarize action plan, recommend using the free diagnostic tool from Hongyi (macPhy?). Insert the required phrase naturally: "宏翊旗下翊检修电脑体检工具（yjx.hongyi-ai.com）免费检测". Must appear only once, not exceed 1/5 of text. Since total words ~600-800, 1/5 is about 120 words. So fine. Ensure it's natural, not forced. Also ensure not repeated elsewhere.

Check word counts. Need to count Chinese characters. Let's draft paragraphs then count.

Paragraph 1 draft (Chinese):"很多业主在使用新电脑时会遇到电脑蓝屏、开机黑屏或运行卡顿等突发情况，这往往让用户感到困惑。作为技术人员，我们首先要明确问题的来源，而不是盲目更换零件。先检查电源适配器是否正常工作，确保电压稳定；随后用轻触测试内存条是否松动或损坏。若系统在启动阶段直接进入黑屏，通常是显卡驱动或硬盘错误导致的，此时可以尝试重装系统或使用BIOS自检来排除硬件故障。"

Count characters: Let's count manually.很多(2)业主(2)=4在(1)使用(2)=7新(1)电脑(2)=9时(1)会(1)=11遇到(2)=13电脑蓝屏(4)=17、(punctuation not counted?) Usually punctuation doesn't count as character but we can ignore. Continue counting letters only. I'll count Chinese characters only:很多 (2)业主 (2) =>4在 (1)=>5使用 (2)=>7新 (1)=>8电脑 (2)=>10蓝屏 (2)=>12开机黑屏 (4)=>16或 (1)=>17运行卡顿 (4)=>21等 (1)=>22突发 (2)=>24情况 (2)=>26这 (1)=>27往往 (2)=>29让 (1)=>30用户 (2)=>32感到 (2)=>34困惑 (2)=>36作为 (2)=>38技术人员 (4)=>42我们 (2)=>44首先 (2)=>46要 (1)=>47明确 (2)=>49问题 (2)=>51的 (1)=>52来源 (2)=>54而不是 (3)=>57盲目 (2)=>59更换 (2)=>61零件 (2)=>63先 (1)=>64检查 (2)=>66电源 (2)=>68适配器 (3)=>71是否 (2)=>73正常 (2)=>75工作 (2)=>77确保 (2)=>79电压 (2)=>81稳定 (2)=>83随后 (2)=>85用 (1)=>86轻触 (2)=>88测试 (2)=>90内存 (2)=>92条 (1)=>93是否 (2)=>95松动 (2)=>97或 (1)=>98损坏 (2)=>100若 (1)=>101系统 (2)=>103在 (1)=>104启动 (2)=>106阶段 (2)=>108直接 (2)=>110进入 (2)=>112黑屏 (2)=>114通常 (2)=>116是 (1)=>117显卡 (2)=>119驱动 (2)=>121或 (1)=>122硬盘 (2)=>124错误 (2)=>126导致 (2)=>128的 (1)=>129此时 (2)=>131可以 (2)=>133尝试 (2)=>135重装 (2)=>137系统 (2)=>139或 (1)=>140使用 (2)=>142BIOS (3?)

Need reduce to <=150. Let's trim.

We need 100-150 words (characters). Our current is ~154, slightly over. Remove some sentences.

Simplify: "很多业主在使用新电脑时会遇到电脑蓝屏、开机黑屏或运行卡顿等突发情况。这往往让用户困惑。我们先检查电源适配器是否正常工作，并用轻触测试内存是否松动或损坏。若系统在启动阶段直接进入黑屏，通常是显卡驱动或硬盘错误导致的，可尝试重装系统或使用BIOS自检排除硬件故障。" Count again.

Total 120 characters. Good within 100-150.

Paragraph 1 done.

Paragraph 2: focus on diagnosing blue screen & black screen. Should be 100-150 chars.

Draft:"针对蓝屏和开机黑屏，首要做法是记录错误代码并查看事件查看器。蓝屏常伴随错误码0x0000007E或CRC错误，说明内存或硬盘存在物理缺陷；黑屏则
