After installing win7, the problem summary and partial solution

[1. After the installation of Win7, the game cannot be full screen]

Start-Run-Enter regedit and press Enter to open the registry, then HKEY_LOCAL_MacHINE-SYSTEM- ―ControlSet001-Control-GraphicsDriver-Configuration- Right-click on Configuration, select Find, enter Scaling, search for Scaling in the box on the right, and change the value of Scaling to 3.

This method works for most games, but the effect on CF is not very obvious. There are a few differences between different graphics cards. There is also a method, the effect is better, but only for the Warcraft Ice Throne, you can run the game at full resolution, the picture is very delicate. To do this, open Notepad, copy the following to Notepad, and save it as a registry file with a .reg extension. Then double-click on the import.

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER"Software"Blizzard Entertainment"Warcraft III"Video]
"reswidth"=dWord:00000556
"resheight"=dWord:00000300

But this is for our 4535 model 1366×768 screen resolution. If you are not at this resolution, you need to modify the value behind dWord. It is calculated by converting decimal to hexadecimal. The 1366 hexadecimal is 556, the hexadecimal is 300; so if your monitor is 1280×800 resolution, and the 1280 hex is 500, the hexadecimal is 320, you need Replace the last 3 digits of the last two lines with 500 and 320, respectively, and then import them into a registry file. Because everyone's resolution is not the same, I can't list them after they are converted, so I only have trouble to convert them according to my own situation.

[2. Can not find the optical drive after installing Win7]

Especially the 4736 series of the BIOS will encounter such a problem. It is said that the official 1.07 version of the BIOS used to modify itself is a bit problematic, which will cause such problems after adding SLIC2.1 to BiOS. You can try this method:
Install win7 in the AHCI mode, download the official SATA driver after installing Win7, and restart the computer. Will find that there is still no optical drive. Then turn it off and restart it again. At this time, the optical drive can usually come back.
For those who have already installed Win7 in IDE mode, but are not willing to reinstall, you can start from the start - run - enter regedit to open the registry, and then navigate to HKEY_LOCAL_MacHINE "SYSTEM" CurrentControlSet "service" Smsahci, change the value of the start key on the right to 0. Please be cautious, otherwise it will cause a blue screen after reboot. After the modification is completed, restart the computer, boot into BiOS and set the mode to AHCI, then save and exit. After entering Windows again, you will be prompted to find new hardware, then install the official SATA driver. The subsequent operations are the same as mentioned above. The problem is solved after shutdown.

[3. Problems with frequent network disconnection after installing Win7]

A lot of machine friends in the group complained that they frequently dropped the line after win7, suspected to be win7 or network card driver. The problem. In fact, this is not the fault of win7 nor the driver, but a setting that is turned on by default in order to save power. As long as we cancel, this problem will not occur. Go to Control Panel - Network and Sharing Center - Change Adapter Settings. Right click on the local connection or wireless network connection - Properties - Configuration - Power Management, the check box before "Allow the computer to turn off this device to save power" is canceled, then apply, OK, it is OK. This issue is resolved.

[4. After the installation of Win7, there is a sound or current sound]

After installing the baby shoes, you will find that the sound has a pop or current sound. After installing 4530G, my hardware is driven by Win7. All the music is normal. So I didn't care. I chatted with my friends and chatted with QQ. As a result, the other party couldn't hear my voice. It was all harsh. Current sound and pop sound. Recall that the sound card driver was not installed, but the driver that comes with win7. Later, I downloaded the official latest win7 driver from the official website (there is no Vista under Win7), and the video voice is normal. It is recommended to use the children's shoes with sound problems to go to the official website to download different versions of the sound card driver to try. If there is still a popping sound, it is recommended to install the sound card brand's own driver directly, and most of them can be solved. However, this is not integrated with Dolby. If you want Dolby, you can install Dolby's program separately.

[5. After the installation of Win7, the system becomes slower and change the card]

In fact, the requirements of Win7 system are not as high as Vista, and the speed can basically compete with XP. The reason why I changed the win7 and felt that the system changed the card, not the problem that win7 takes up too much resources, but some of our small settings have not met the appetite of win7. Start - Run - Enter MSConfig and enter the system configuration. In the second tab "Boot", click on "Advanced Options" and set the "Number of Processors" to the actual number of cores in your processor. Some people will say that dual-core is out in 2005, win7 is out in 2009, isn't win7 still supporting dual-core? ! Win7 of course can support dual-core very well, it can identify dual-core and even multi-core, but we set it here, not tell Win7 that you have several cores, but you have to start several cores. You can compare, select the number of processors to 2, and then choose to return to 1, you can clearly feel the performance degradation.
In addition, regular replacement of a theme is also a trick to prevent win7 slow down, you ask me why? I can't explain it either. It is said that this is a bug in Win7.

[6. Cannot install Alipay certificate after installing Win7]

I often buy things on TAOBAO. After installing win7, I found that Alipay's digital certificate is always not safe. It is said that the security of Win7 has been greatly improved, but it seems to be too high. I found a lot of posts and finally found a solution: first set up the IE8 browser: Tools - Internet Options - Advanced, cancel the "Enable Memory Protection to help reduce online attacks". Next, click Tools - Internet Options - Security to disable "Enable Protected Mode"; then go to Control Panel - User Accounts - Change User Account Control Settings, set the alert level to the lowest level, and finally restart the computer.

[7. Bluetooth cannot be used after installing Win7]

First make sure you have Bluetooth hardware instead of Bluetooth module. Once again, the correct driver is installed, which corresponds to the operating system used and the Bluetooth hardware brand. Some machines use the same model with several different brands of Bluetooth devices, and the brands cannot drive each other. For example, Broadcom's Bluetooth, you have a Foxconn driver to install, the bulls are not right, of course not. In fact, according to my personal opinion, there is no need to install the Bluetooth driver of the official website. It is big and slow, and the operation is complicated. A small hardware driver like Bluetooth, the win7 driver package comes with it. After installing the system, turn on the Bluetooth device and Win7 will automatically recognize and install the Bluetooth driver. It is also very simple to transfer files. Just right click on the Bluetooth icon and select Send File and Accept File.

[8. Regarding whether to open NCQ]

After running Win7, I ran a benchmark with HD and felt it was OK. So I want to open the NCQ try. So I got AMD_SB700_AHCI and RAIDXpert, first updated the disk driver in the device management, after testing, this change can not be rolled back. After two reboots, NCQ was finally opened in RAIDXpert. Hurry and ran again, but the result was disappointing. In addition to the increased burst transfer rate, the other... I hope it is an illusion. And after turning on the NCQ, you can't see the temperature of the hard disk, so you want to open the NCQ children's shoes to measure it.
