Distress!! Broken motherboard? Computers are fine except for the Internet

If the motherboard is broken, the computer can't be opened at all, even Windows can't enter, as long as it can still enter the system, there is basically nothing wrong with the hardware, it should be a problem with the software settings, or there is a problem with the driver, you can redo the system,

Unfortunately DX, the maintenance guy still says so, and you can't do anything about it when you come online.

It's a hardware problem, and as for the cause: either your hardware is too bad, or that level of repair is too bad.

Solution: Look for a better repairer.

Is it still just not possible to access the internet today?

If so, it may be that your network card or network card slot is broken.

Try to change the slot, and if you can get on it to someone else, it's the problem that your network cable is still on the network.

Problems with network cards or crystal heads. If you are a brand machine, the maintenance of the motherboard often has a long warranty period, the maintenance department can apply to the company for free If he replaces the network card for you, you need to pay for it yourself If he gives you a free replacement of the motherboard, of course, it is the best...

Or the reason for the network card, if your motherboard has an integrated network card, it is easy to cause the installation of a separate network card after it is broken.

Did you repair it in a regular place, it's likely that he didn't pay attention to it when he repaired it. There is static electricity on the hand, so it is easy to burn the motherboard.

The repaired ones are for you to burn out! Now the level of maintenance personnel is not as high as mine, and if it is broken, I will replace it and plug it in.

The network card driver is removed and reinstalled, and the network cable is not problematic.

Take a look at the network card, reinstall the driver, and don't listen to their nonsense.

Try a different network card.

Buy an independent network card, less than 50 yuan is OK.

1) Reinstall the operating system first, don't install software, patches, drivers, etc., and see if there is still a problem with booting? If you don't install drivers, patches, and software step by step, and find something that isn't suitable, don't install it.

Please note: If you restore the system or reinstall it, when installing drivers, patches, software and other things, be sure not to install the things that affect your accident this time, otherwise it will be restored or reinstalled in vain.

2) In terms of hardware, such as hard disk, memory, graphics card, motherboard, etc., if there is a problem, if it is caused by hardware problems, it is recommended to overhaul it.

3) The above is caused by system problems, and the following is caused by network problems.

1. If it is a problem with the broadband itself, first directly connect to the broadband network cable for testing, and if it is a broadband problem, contact the broadband customer service to solve it.

2. If it is a problem with the router, if it can be used originally, it cannot be used for the time being, my own practice is to disconnect the power supply of the router and plug it in, and I will see. In there is a factory reset, it can be used from the new settings (this is under the premise of the correct physical connection, sometimes caused by the router's slow or failed IP address search, not that the router is broken).

If it can't be solved all the time, it is recommended to call the customer service of the router, they have **** guidance, I encounter a problem that I can't solve by myself, it is very useful to consult the advice they gave, and they will give the correct advice for your settings or operations.

3. If you turn off the wireless switch and turn it on, if it is a wireless connection with software, it is normal for the software to be difficult to use and often have problems, there is no better way, use a router. In addition, it is caused by the network card driver is not or is not suitable, and whether there is a problem with the network cable interface or network cable.

4. If it is caused by system problems, it is recommended to restore the system or reinstall it.

Generally, the automatic shutdown may be caused by the high temperature caused by too much dust in the CPU fan, if so, clean up the dust of the CPU fan and heat sink, add new heat dissipation silicone grease, if the heat dissipation fan is broken, change it. If it's not a problem, it may be caused by problems with motherboard parts or power supplies, voltage instability, hard disk failure, hardware overclocking, etc., and the new hardware is incompatible. In addition, a Trojan horse can also cause a shutdown due to a system failure, but the probability of this is very small, restore the system or try to reinstall it.

If it automatically shuts down or standby without operation, it may be a problem with the settings. Right-click on the desktop to select Properties Screen Saver Power Supply Select a scenario that suits you from the drop-down list in Power Usage Scenarios, and set Never in the list of Monitor Off, Hard Disk Off, System Standby, and so on below (or set a suitable time).

Open the control panel All Control Panel Items Power Options Change schedule settings Select Turn off the monitor (select Never or Set Time), select Change Computer Sleep Time, and select Never or select the appropriate time (Win7 or Win8) from the drop-down list next to Make Computer Sleep.

See if it's caused by the settings above.

If the battery is broken, it won't light up at all, in this case, it may be that the screen is broken, or it may be that there is a problem with the graphics card.

If the mouse doesn't light up, there may be a problem with the power cord, change the power cord!

It may be that the hard disk is bad due to power supply, but if it is really a power supply problem, not only the hard disk is a problem, but also other equipment, such as memory modules, motherboards, CPUs, PCI cards, etc.

The hard disk can not be detected, as long as it is not caused by power supply or physical bad sectors, other reasons can be repaired, such as DG350FREE X86 software can be repaired, it is recommended to repair the PE system, if the PE system does not have this software can be installed in the U disk.

The head is broken and burned, and the repair shop can't repair it outside, but this kind of situation is rare, not necessarily the head is broken, it may be difficult to repair or can't check out the problem there to fool you.

Improper power failure and other reasons may cause the disk boot area to be corrupted, resulting in the hard disk not being found. You can use disk detection software to detect and repair, if you can't fix it, you can only replace it.

There are too many problems, and not being able to detect the hard drive does not mean that the hard drive must be broken. If you don't know how to use a computer, you can only trust the person who repairs it.

You try to re-partition the hard drive first. This can also happen if there is an error in the partitioned table.

If the hard drive is broken, the best thing to do is to replace it with a hard drive, if it can be good, it will directly prove the problem with the hard drive.

Your problem is clear, the hard drive is broken.

1. 3470 with B75 is just right, (GIGABYTE GA-B75M-D3V 600 blocks, room for upgrade?) I don't think it's necessary, this computer can be used for more than a year, and who knows what will happen when the time comes, if you have to leave room for i7, use Gigabyte GA-Z77-D3H for 400 more.

Second, compatibility is nothing, everyone says that rainbow is not good, anyway, I don't see it (there is no big difference in high-end products, and there are too many junk goods below 400 (in order to take care of low-end users). If you don't think it's good to use the 650ti of Yingchi and Yingzhong (660 is also OK).

3. Personal opinion: Swap the price of the CPU and the graphics card for i3 and GTX660 for the graphics card

With the i5 processor, the overall ** went up to about 3500.

Motherboard recommended ASUS Z77-A motherboard JD price 759 yuan.

It's better to buy a brand machine to save trouble and be safer.

If you want to use a miserable red graphics card, use the U series, otherwise you will change the brand.

Estimate your motherboard battery is dead, and now there are no boot items.

Here's the detailed setup of the BIOS:

Generally, the motherboard is prompted when it is turned on,There is a shortcut key to help you quickly choose the boot startup device such as holding,ESC or F12What will appear after pressing a very simple option。 For example, the words *** cd or something, hd or something, according to different devices are still different. Therefore, as long as you know what the name of your hard drive is, you can choose it directly.

The first boot device is to set the hard disk as the first boot.

The second boot device is to set the car wide hard disk to the second boot.

The third boot device is to set the hard disk to the third boot.

In First Boot Devi, select Hard Disk to turn the hard disk as the first boot.

HDD-0, HDD-1, HDD-2 are older motherboards.

The number after the HDD indicates the number of hard drives, and a total of 4 hard drives can be connected, starting from 0 to ending with 3. They are: HDD-0, HDD-1, HDD-2, HDD-3

Ordinary machines, only one hard disk.

The setting method is generally in the Advanced BIOS Features section (the older motherboard is in the BIOS Feature Setup), and then select the first boot device (also called the motherboard is called Boot Sequence) to set it as CD-ROM. Helpful.
