After replacing the motherboard, the boot speed is very slow, and it seems that the display performa

This is caused by your network card having the boot function of the boot rom chip enabled, and the network card has a pxe boot chip. It can be solved like this:

If the network card is integrated on the motherboard, or the boot program on the network is written into the BIOS, you can modify the boot order of the system from the BIOS settings, such as setting the hard disk to boot first, or disabling the network card from booting the system from the BIOS.

If the NIC is not integrated, you can unplug the boot chip on the NIC or use the NIC to set up the program, disable the bootrom boot function of the NIC or turn it off, and then after booting, when "press shift-f10 configure...... appearsImmediately press the "Shift+F10" key combination, enter the menu, set the Boot Order ROM to Disable from line 4, and then press the F4 key to save and exit.

Turn on the pxe to start, boot into the cmos settings, turn off the pxe startup item will not appear this item.

Why is the computer still stuck and slow after changing the system, and what is the reason? Look what the guy says.

Causes of the problem and solutions.

1.Check the application software or drivers.

Some programs slow down the computer system when it starts. If this is the reason, we can start from the "safe mode". Because this is the original boot, Safe Mode runs slower than it did normally.

However, if you start up in Safe Mode and find that your computer starts up faster than you normally would, there may be a program that's causing your system to boot up slower.

2.Too many desktop icons can get you into trouble.

Having too many icons on the desktop can also slow down the system boot up. Every time Windows starts up and displays the desktop, you need to find the icons of the desktop shortcuts one by one and load them, the more icons you have, the more time it takes, of course.

It is recommended that you put the desktop icons that you don't use often in a special folder or delete them altogether!

3.Remove the random starter.

You can use Kingsoft Poison's boot optimization function to increase the boot speed with one click.

If your computer is infected with a virus, the system will run significantly slower. It is recommended to use Kingsoft Antivirus's quick detection and killing function to kill computer diseases and viruses with one click, and improve the running speed of the computer!

First of all, judging from your description, there are a number of problems after the motherboard of the original computer was damaged and replaced or repaired. This is mainly to find out whether the motherboard has been replaced with a new motherboard after the computer is brought back, especially whether there is a different lead sock and incompatibility with the brand or model used before;

Secondly, if the motherboard is replaced, the operating system must be reinstalled, and if the corresponding hardware driver is not correct after the new installation of the operating system, the problem situation you described will also occur.

Configuration compatibility, your processor configuration has improved, but have your power supply and other configurations also improved?

First of all, from your description, there are several problems with the motherboard of the original computer after it was damaged and taken out to replace or repair. This is mainly to find out whether the motherboard has been replaced with a new motherboard after the computer is brought back, especially whether it is different or incompatible with the brand or model used before;

Secondly, if you replace the motherboard, you must reinstall the operating system, and if the corresponding hardware driver is not correct after the new installation of the operating system, the problem situation you described will also occur.

Is there a problem with the motherboard driver, is it the same motherboard?

1. In the operating system before the motherboard is replaced, various drivers are perfect, so it will run normally and smoothly.

2. After replacing the new motherboard, the system will automatically install the drivers of the device on the new motherboard, but the automatic check often cannot fully install these drivers, so the computer will slow down.

3. It is recommended to reinstall the system once after replacing the motherboard, or use a third-party driver detection tool to detect the driver and upgrade it to ensure that all the replaced hardware can be used normally to ensure that the computer returns to normal response speed.

Is there too many startup items, and also, see if the C drive is full.

It's best to redo the system, presumably because it's aging.

Preliminary estimate of CPU precedent problem. In the end, the board is not burned, but the speed is sleepy and slow, so it should not be about the power supply.

Maybe it's because the driver of the motherboard is not installed well after you change the motherboard, it is recommended that you delete all the drivers and reinstall the bridge test ruler to try it early.

You should try to install the system. It's really not advisable to change the motherboard without reinstalling the system!

There are many reasons for this.

It is necessary to find out first, whether the network speed is relatively slow, or the speed of the machine system is relatively slow1) If the network speed is slow, upgrade the network environment of the Internet.

2) If the machine itself is running slowly, then it depends on the configuration of your machine and the operation of the computer system.

3) If the computer configuration is low, then the only way to update and upgrade the hard disk configuration is 4) If the system is not running well, it is recommended that you reinstall the operating system.

1.There may be incompatibility issues.

2.You can try to refresh the system to change to w8 Try ! ~

Send me the configuration of your computer.

The motherboard does not match the other components.

Is there a reinstall system after changing the motherboard?

Is that the configuration too low?。。

If you want to be fast with a computer:

1. Make sure that the local system is virus-free;

2. Replace the CPU within the range supported by the motherboard;

3. Install a solid state disk as a system boot disk (solid state hard disk is better than 7200 rpm mechanical hard disk, 7200 rpm mechanical hard disk is better than 5400 rpm mechanical hard disk);

4. Add memory (preferably dual-channel);

5. If it is an integrated graphics card, then replace the discrete graphics card (the general notebook cannot be replaced);

6. Make the partition reasonable (try to increase the C disk);

7. Install non-core applications under the D drive;

8. Make the drive complete and optimal (try to drive the original factory);

9. Clean up the startup items;

10. Clean up the plug-in;

11. Modify the self-test time (30 seconds to 3 seconds);

12. Set the best performance of the system instead of the best appearance;

13. Clean up disk fragments regularly (if it is a solid state drive, it can be ignored);

14. Try not to set a personalized tablecloth (if it is a solid state drive, it can be ignored);

15. Clean up the background garbage regularly;

16. It is best to match the system windows

uodate (individual options can be exceptional, e.g. IE version);

17. It is best to get all the system security vulnerability patches;

18. Try to install the pure version of the system, try not to install the ghost version;

19. Clean up the IE cache every 10 months;

It is recommended to reinstall the system first to eliminate software problems;

If you can't think about the hardware anymore, look for me.
