The startup screen saver cannot be activated, resulting in the inability to enter the desktop and a black screen on the computer, affecting normal use. PHP editor Yuzai brings you detailed solutions to help you quickly solve this problem and restore normal computer use.
2. When the computer is turned on, only the screen saver cannot enter the desktop
1. Whether the cooling fan on the back of the power supply is not spinning. Note: If the power supply is broken, its cooling fan will definitely not spin, but it is also possible that the fan itself is broken, so you should also check other places to determine whether the power supply is broken.
2. Is the POWER indicator light on the computer host panel off? Note: The LED indicators on the computer host indicate the working status of the power supply, hard disk, and floppy disk. If these LED indicators do not light up, it is likely that the power supply is not supplying power. 3. Can you hear the working sound of the floppy drive, hard disk or optical drive during startup? Note: The computer will check these hardware devices when starting. If you cannot hear these sounds, it means that the power is not supplied to them at all. If it is determined that the power supply is not working, how to solve the problem? Let me tell you in detail: If it is determined that the power supply is not working, do not think that the power supply is broken first. You can check the following places: 1. Is the main switch tripped? Is the plug connected? If it is loose, if an extension cord is used, check whether the fuse of the extension cord is blown. 2. Whether the power supply stops supplying power due to a short circuit: Since the power supply itself is designed to detect short circuits, it will automatically cut off all power supplies when it detects a short circuit in the output circuit, causing the power supply to not work. This situation can be seen from the operation of the cooling fan. If the power supply is good and there is a short circuit somewhere inside the host, when the power is turned on, you will find that the fan stops after rotating and makes a hissing sound. , if the fan rotates a few times after turning off the switch, this symptom is a typical short circuit phenomenon. To find out the component causing the short circuit, you can unplug all the DC output connectors from the power supply. If the short circuit disappears after all the connectors are unplugged, it means that the circuit of a certain component is short circuited. You can Insert the connectors back one by one until the short circuit occurs again, then you can confirm that the component is broken and replace it. Please note that the power must be turned off before unplugging and plugging connectors to avoid burning computer parts. 3. Is the DC output of the power supply normal? If the above three conditions have been checked and the power supply still does not work, you can use a three-purpose ammeter to measure the DC output of the power supply. If there is no output at all, it means that the power supply If it itself is broken, replacing the power supply should solve the problem.
3. What should I do if the computer screen saver cannot be opened?
1. The startup disk set in the BIOS is wrong. Set the startup disk to a CD, floppy disk or U disk, etc., which happens to be on the computer. There is a U disk, floppy disk or CD;
2. The hard disk contact is not good, the hard disk mode is set incorrectly or the hard disk MBR is wrong;
3. Check the optical drive, U disk, floppy disk, etc., and remove them if any;
4. Enter the BIOS Set the hard disk startup in the startup item settings as the first startup disk, and try to restart to see if it can boot;
5. Enter the BIOS, modify the hard disk mode, and try to restart after setting different modes to see if it can boot;
6. Disassemble the case, unplug the hard drive cable and reconnect it, and try again to see if it can be booted; during the boot process, listen and touch the hard drive to see if it rotates normally;
7. Press Ctrl+Alt+Del to restart the computer.
8. Press F8 to enter the mode and select the last correct configuration or normal startup. If the above method cannot solve the problem, it is recommended to reinstall the system.
4. What should I do if I cannot enter the desktop due to a screen saver on startup?
Press and hold the F8 key on the keyboard when booting, and select to enter the safe mode startup interface; then after entering Windows, right-click a blank space on the computer desktop and select "Personalize"/Screen Protection options; then choose to cancel "Password Protection" and then restart the computer. Two: As long as you press the shift key on the keyboard when entering Windows, it will skip the contents of the startup folder without starting the screensaver, and you can enter the system.
按我下面说的一步一步来，你就能回到你原来的帐户以前你没有建立过用户吧！ 一看就知道了， 你原先用的是默认的administrator这个用户，一但你新建立了用户，默认的用户就会被覆盖掉 你按我说的一步一步来 第一步：打开控制面板 第二步：双击“用户帐户”
第三步：点击“更改用户登陆和注销方式”
第四步：把“使用欢迎屏幕”前面的对号点掉 最后一步：点“开始”菜单，选择“注销”命令 然后登陆用户名用“administrator”密码不用输入，登陆就好 如果你记不住这个名字，就用笔先写下来， 现在你就可以用这个帐户登陆了，不过为了以后还用这个帐户，所以你还需要做以下的设置 第一：打开“控制面板”选择里面的“管理工具”，然后选择“计算机管理”，打开后左侧有“本地用户和组”点它前面的加号，然后点“用户”
这时右边有一个你刚才建立的用户，鼠标右键点它把它删除了就好 第二：打开控制面板，双击“用户帐户”，点击“更改用户登陆和注销方式”。把“使用欢迎屏幕”前面的对号重新点上
1、按下“Ctrl+Alt+Del”组合键打开任务管理器（如果按这三个健也不管用，直接重装系统吧，呵），点击进程选项卡，看看里面是不是有explorer.exe进程，如果有把它关闭，然后点击“文件”→“新建任务”，在打开的“创建新任务”对话框中输入“explorer”，单击“确定”按钮后，稍等一下就可以见到桌面图标了。
2、如果上述的创建新任务，确定或回车时提示说找不到explorer.exe文件，说明该文件被删除了，你可以用U盘到其它电脑的C:WINDOWS文件夹中复制explorer.exe文件到电脑上的C:WINDOWS文件夹中。
3、在重启后下次进入系统时，很可能还是看不到桌面图标，这说明该方法不能彻底解决，可以单击“开始→运行”，在打开的“运行”对话框中输入“regedit”（引号不要输入），按“确定”或回车键Enter，打开注册表编辑器，定位到HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsNTCurrentVersionWinlogon，然后查看该分支下的Shell值是否为“Explorer.exe”。如果不是，请手动修改为“Explorer.exe”。
电脑开机后出现黑屏的原因有很多，一般也很容易解决的，根据我的接触，一般的开机黑屏常常会有以下几点状况：电脑死机，有图像。重启时黑屏，且无 “滴”的开机声。电源风机、CPU风机、显卡风机都转。鼠标亮。键盘不亮。前面板两灯都亮，无闪烁。光驱能弹出。 请试一下以下几个步骤：
一，bios放电，至少3分钟，开机，如能点亮，则是bios的设置问题。
二，拔掉电源线，按开机按钮3次，每次3秒，可以放静电。
三，最小化系统，拔掉显示器，鼠标，键盘，网线等所有连线：拔掉显卡，网卡，光驱，硬盘，内存，前置usb连线等：只保留电源，主板，cpu。
如果你具备一定的组装电脑的能力的话，最好把电源按钮连线，reset按钮连线也拔掉，用起子短路开机，我遇到过reset按钮被卡住，而黑屏的故障。
可以按照以下的步骤排查解决：
这应该是你电脑的硬件问题导致的原因吧。显卡或内存cpu，或风扇的接触不良和松动或有灰尘覆盖，（拔下橡皮擦擦）。内存cpu过热，散热性不好！（开机时间不要太长，关机散热）。
电脑存在恶评插件! (扫描出来，立即清理)或磁盘碎片过多，（使用腾讯电脑管家），清理碎片！如果还是不行，说明系统文件丢失了！或者系统内存有很严重的错误了！
电脑开机停留在LOGO界面不动需要通过以下故障排查和解决：
1.通常电脑一开机，首先是进行设备自检，如果卡屏在主板LOGO图片这里，多数情况是硬盘检测没有过去，可以试着给硬盘换下数据线，如果没有线也可以试着把数据线两头对换一下，再换个主板上的接口。
2.主板BIOS出错，一些主板有防入侵机制。如果最近有跟换过配件，也可能是主板BIOS的错误引起。解决的办法是开机按DEL键，进入主板BIOS，初始化BIOS设置信息，再按F10保存退出重启电脑。
3.检查机器是否有外接设备连接，U盘、移动硬盘等等外接设备可能插在电脑USB口上忘记拔掉了，造成主板自检卡主通过不了。解决的办法就是拔出多余的外接设备，再重启电脑。
4.检查一下键盘和鼠标是否接反。这里指的是PS/2接口的键盘鼠标，很多人大意，把键盘和鼠标的接口插反了，造成开机电脑的自检错误以至于卡屏。解决的办法，先关机，重新接过键盘鼠标，通常紫色的接口为键盘，绿色接口为鼠标。
5.回到第2点，还是硬件故障，如果硬盘换过数据线后还是无效，也可以先试着拔掉硬盘的数据线不接，然后开机测试。看是否还会卡在LOGO屏这里，没有的话，估计就是硬盘故障了。解决的方法只有更换硬盘了。
开不了机或开机进不去，是与您关机前的不当操作有关系吧？比如：玩游戏、看视频、操作大的东西、使用电脑时间长造成的卡引起的吧？
或下载了不合适的东西、或删除了系统文件、或断电关机等，故障不会无缘无故的发生吧？
按电源键反复开关机试试，放一段时间试试，确实不可以就重装系统吧，如果自己重装不了，花30元到维修那里找维修的人帮助您。
只要自己的电脑不卡机、蓝屏、突然关机，开机就不会这样了。有问题请您追问我。
