Lenovo Y470 boots up slowly, the screen is blank, light blue, what s going on? Kneel and ask for hel

1. Redo the system.

2. Install the software in a partition other than the C drive.

3. Try to keep the C drive and install less software.

Whether it is Windows XP or Windows 7, you need to keep the C drive partition relatively clean, because the system will load the C drive partition and desktop icon when it boots, so the more things you have about the C drive and desktop icon, the slower the boot will be.

I think it's a problem with the hard disk reading ability,And it's a software problem,Y470The hard disk uses4K alignment storage technology,When it's not aligned,The reading ability is poor,Slow to boot,My computer has also had similar problems,It's done after processing,The next software alignment。

You can also install an SSD hard disk, I installed an SSD, and it takes about 20 seconds to boot up.

Caused by high virtual memory usage, there are too many software programs launched when booting, or there is a virus, it is better to redo the system, it is best to format or repartition all partitions.

After entering the system,Go to the official website of the driver to update all drivers to the highest version,If it's still not good, then the graphics card driver should be able to drive the next official version of any version of the driver!

System problems: Don't install 64-bit or flagship system files if you change the system, and the files are too complicated.

It is recommended that you: segment infiltration.

1. Clear the system junk files (such as unused software programs in the system disk, redundant drivers of hardware, cache files of web pages, etc.);

2. Load the project when the computer starts up (there are two methods, one is to start-run-msconfig-start-remove unnecessary startup items;

3. Use Kingsoft Guardian's system optimization, garbage cleaning and other functions to optimize the computer startup project, and at the same time, you can also optimize other related settings and parameters of the computer;

4. Minimize the icons on the computer desktop (some infrequently used or software shortcuts try to create a folder and store all of them in it), so that the computer will save some time when it starts to load the desktop, and it will also save time when it is updated at any time in the future operation;

5. After opening a certain software, if you don't use it for the time being and you have to open other software programs, please close the original program, so that the memory and CPU occupancy will decrease, so as to improve the running speed of the computer!

Hope mine will help you!

The following section is an explanation of the test by others. Hope it helps.

According to my years of experience, you should first check the hard disk, there may be bad sectors that will cause the computer to be black and white, that is because your system files, or graphics card drivers because of the hard disk generated bad sectors and lost data, so the white screen, black screen.

1: Many people are trying to reinstall the system, and you might as well try this method.

2: But the problem is multifaceted, the graphics card itself fails, and the same situation occurs, generally a white screen, and a sudden black screen is very rare, and it is OK to troubleshoot the graphics card

3: Then check whether the capacitor on the motherboard has the phenomenon of expansion, blackening of antennae, etc., because the capacitor is to regulate the current and voltage of the motherboard, so it has something to do with him!

Basically, it's a matter of these reasons! Of course, if you can be sure that the monitor is okay, the above methods should help you!

The latest version of the driver is not the best fit on the line Don't update the driver of the old You go to the official website to try the driver of this model It's really not good to take the after-sales service.
