100 Reward!!! Question 100 about computer exchange system

You install windows7 in the E disk,He will also replace some system files of the C disk,This of course also includes the sound file, of course, the original file will not be restored after you uninstall windows7,So in ** because there is no support file so it can't make sound。 In this way, you have to reinstall the XP system, restore the original files (can not be recovered with a tool, can only reinstall the system, otherwise it may lead to the system because of compatibility problems and can not run, this is a hateful phenomenon of Windows), pay attention to the data backup before reinstallation, and then try the sound, it should be good, if it is not good, change the microphone.

There is no special need to use a single system win 7 is now a lot of software is not supported, your problem should be windows xp and windows 7 conflict, similar to ie8 you install dual system windows 7 has an ie8 you want to install an ie8 in windows xp is not installed.

Go to the Audio Screen Manager to see if the microphone settings are muted or the volume is low! After changing to XP, the microphone is generally muted by default, but it does not affect the recording function.

Change the microphone, if it's not good, just make a single system, and the two systems may have software incompatibility.

Answer: 1, you can change it to a 32-bit one, but I don't think it's necessary, Dell has limitations, but it can also break through. As soon as you change it, you become a pirate. 64-bit for 32-bit is not easy to find a driver.

The installation of the version is fast,Stability and instability depend on how well it is cracked,However,Now win7 is cracked well,It's just easy to be blacked out,Because you buy those ghost discs and come back to install them into pirated versions。

3.Formatting is generally just formatting the C drive, you can rest assured, the things of other disks are generally fine, the important thing is that the important things in your C drive are backed up.

4.It's not necessarily impossible to use.,It's good that the driver can be installed.,The Bluetooth of the notebook is useless now.,WiFi,Wireless connection and the like.,Just install the wireless network card driver.。

5.This thing seems to be Dell's own software.,If you install the ghost version.,There shouldn't be this function.,But,This thing doesn't have much effect.,Personal feeling.。

6.It can be used, the key is the driver, and it can be used after installation.

7.Same as the 5th.

IdeaPad Entertainment Ben.

The performance is a little better. Words that I understand. Usually the eyes of ordinary people talk about memory. CPU and graphics card memory handles.

Use it to watch movies and play games. At your price point, I recommend the Y460.

This machine is selling more on National Day. And** more wearable. It is not easy to be cheated by others.

The Y460 is positioned in terms of entertainment. Generally for students. And the appearance is more fashionable and unique.

That's about what it looks like. And the dual graphics card switching saves you a lot of performance.

The other machines are not very cost-effective.

After that, it's up to you to demand it. That's about it.

The Y560 is comparatively larger. So I don't recommend it much.

Also add to your question. I would like to say. Lenovo's Yangtian V series is not for you.

Lenovo's Yangtian series is positioned as a commercial model. I don't think you should be able to use the hard disk protection function of APS.

The i3 and i5 are relatively good. However, there is also a higher-end configuration of the i7.

That's about it. It's rare for you to get such a high score. I won't be able to explain it to you clearly. Hehe.
