The computer master is coming, and he has encountered a problem. How many points you need. 30

Since you have restored the system, then the system should be fine, you should check the interface of the audio cable to the computer, shut down with a cotton swab sticky alcohol, it may be into the dust, if it can't be solved, it depends on whether your sound card is integrated, go to the merchant who sells your computer to repair it. If you have a standalone sound card, you just need to find another sound card to try it, and you can judge whether the sound card is broken.

If there is noise in the speaker,First of all, make sure it comes from**,The method is very simple,It is to turn on the speaker,Dial the sound source line to see if there is any,If there is, there is a problem with the speaker,If not, there is a problem with the sound card。

There are also some things that may produce noise if the contact is not good, and the way to deal with it is to rotate the contact place.

The sound card is broken, and it is certain that the analog amplifier circuit at the end of the sound card is damaged, if the circuit before the end pole is damaged, there is no normal sound at all, for example, the system startup sound If there is a normal startup sound, it can mean that the sound card A d d A circuit is good The rear pole amplification circuit of the sound card is damaged The volume drive circuit is damaged The hardware is faulty Be sure to repair or replace a PCI sound card.

First, it's certainly not a sound problem...

Second. ,, certainly not poisoning.

Third... According to your several tests, I think it's the problem with the speaker jack on your host and the problem with the sound card Since it's good to plug in ***, it should be its problem.

This should be a simple question.

1. If there is sound in the system, it means that the sound card is driven normally, otherwise there is no sound at all.

2. Suddenly there is noise, and it is not a speaker problem, it can only be a hardware problem of the sound card.

Suggestion: Try a different sound card.

I've seen how many or how many people have this question.

Broken sound cards are generally caused by a humid environment.

It is recommended to buy a separate sound card for 30 yuan.

1.There is a source of interference next to the computer.

2.You turn the mic's sound on and turn it off!

3.The sound card is broken, but this is less likely.

You change the speaker and take a look.。。

It is very likely that there is interference nearby, or it is possible that the speaker is broken.

Do you have any peripherals that use batteries?

Such as microphone headphones and the like.

Give their batteries a change and see.

With the substitution method, it may be incompatible!

Is there such a thing? Turn off the computer that is in trouble and take a look.

Computers with conflicting IPs can be set to automatically get an IP address.

Maybe it's installed with network monitoring software, similar to the software of the cyber law enforcement officer, just uninstall the software

There are many ways to block the web! It may be that your network card MAC is restricted on the switching routing device, if you are in the domain environment, through VPN, it may be through the web login restricted by Group Policy, and there is network management software or hardware, all have this function, and there may be your company's web Internet access that needs to be verified, it may be domain verification, your branch does not have a VPN, and you can't log in to the domain, so you don't go to the web, only QQ and the like.

It is recommended that you contact your company's network administrator and do not change things without permission, so as not to be able to get on QQ.

Because your Internet is connected, you just can't go to the web!

The external router of the company's headquarters has an ACL access control link, and can only access the internal network, unless you are not using the company's network.

There is no detection of the hard disk or the hard disk does not boot the partition, and there is also a situation where the operating system is not installed. The BIOS settings are booted from the optical drive and are not sold, and there is no blue to put into the disc or the disc does not support booting.

Yingtai is more durable than Onda's, and the main chipset of the motherboard, Yingtai NF4-AM2G uses NFORCE4, Onda NF5S uses MCP55S, or Yingtai is better.

Your CPU needs to be paired with a DDR2 667 to get full performance.

Yingqin 4-am2g is better!!

About your configuration!!

It's OK!!!

Only a little bit of a problem!!

Optical drive ASUS *** recorder 299 hard drive to buy a 160g expensive thing that costs dozens of dollars.

Yours ** are a little more expensive, the installed price of the optical drive is 160, the installed price of 80 hard disk is 390, the CPU installed a machine in the first 2 weeks is 600 yuan, and it has risen a lot recently to 650, how can it be 710. If it is the price quoted by the dealer to you, then make a good price, if the whole machine can go down to 200 yuan, it is OK, if you can't go down, go to a few more.

Most of them are driver issues, or software conflicts.

Try reinstalling the graphics driver to see if that fixes the problem.

Turn on the TV to the PC frequency first,Then restart the computer,It should be OK,If it doesn't work, try to reduce the desktop resolution,The TV sometimes can't display the resolution on the computer, there will be no interface,Is there a sure that your graphics card is adjusted? This is a double display.

To reduce the desktop resolution of the computer, you need to set it according to the requirements of the TV, generally 640 x 480, and the refresh rate is 60Hz

You can set the graphics card of your computer, or set the pass rate.

Perhaps, you should change the line If you can't find someone to repair it, you can find me, hehe.

I'll tell the landlord to give you a more practical suggestion: first of all, 1500 yuan is your consumption amount, right, then it is recommended that you change the motherboard 500 or so, as long as you support 3600 + (more than 3600 is dual-core) CPU board on the line, the board chooses Gigabyte, cost-effective, and then CPU for 4000 + is OK, the price is about 400, and then the memory if you are one generation of DDR, then it is not used, buy 2 DDR2 667 model of 1G memory, 1 is only about 130, which is very cheap, and 2 1G memory can also group dual channels The performance is better than 1 2G, so the memory costs about 260, a total of about 1300; Others can not be changed, you must know that the computer hardware upgrade is very fast, you must burn money if you want to follow the trend, but there is no need, the purpose of buying a computer is enough and not too low and not running smoothly, after spending money, such a configuration is more practical, the current game, software applications, etc., this configuration must be enough, dual-core CPU, 2G memory, 7600GT graphics card is already OK, remember to buy a board to see clearly if it is Nivdia's chip, to match your graphics card; That's all my suggestion, 1500 yuan to buy these just a lot, but also upgraded the computer, more practical and cost-effective!

Change the graphics card

My machine is similar to yours

The CPU can be changed without panic.

Add another 1GB of RAM.

Just change to a graphics card that adapts to the game

It's better to buy a new one than to change it

If you change the CPU, you must change the motherboard, and if you change the motherboard, you must change the memory

Your current memory should be DDR400, to replace it with DDR667, this is not expensive, a 1G is only more than a hundred, and your graphics card is OK, 1500 taels is enough, AMD4000+ is on the line, the recommendation is 4400+, the main frequency, dual core, plus a 570 board is more than a thousand.

Note: As long as the computer is enough, there is no need to pursue the times!

My advice is that you don't rush to change, you will lose money if you change now.

You have to see what game you play is not enough, the current configuration is not bad, if it is enough, you can deal with it first, 1500, keep it for the New Year, but there must be a qualitative leap, it is not suitable to change now, and it is not necessary.

Now the memory is cheaper, if it turns out to be 2*512, you change it to 2*1g.

The 7600GT on the first floor is a very tall graphics card.

Everything else can be changed, only the graphics card should not be changed.

Now the memory is too low, DDR2 1G memory is less than 150 yuan.

I see that you change to a core CPU Intel Core 2 Duo E4300 **700 yuan or so, 500-600 yuan in a motherboard 945, and it is OK to change a 2G memory, but the power supply also has to be changed.

You try not to install any drivers, and you skip the optional driver step during the installation process to see if the drivers are incompatible.

Wait until I extract the image file and upload it.

Generally, the manual installation disk or the brand of OEM system CD-ROM manual installation should be able to succeed The last old Lenovo computer was also handled like this It seems that there is hard disk protection or something The hard disk can only be used on this motherboard Replace it with other computers and install the system back is useless Later, Lenovo's OEM disc was used to deal with it.

I once came across an old computer, dual 256m DDR400. It's also that the installation system can't work, it's not possible to install it halfway.

I thought there was something wrong with the hard drive, all kinds of formatting, all kinds of repartitioning, all kinds of testing of the hard drive, and it took two or three days to do it.

Later, a 256M memory was dismantled, and the system was installed.

It turned out that one of them had a memory problem, and although it could boot the computer, it could not install the system normally.

Also, it is better to use the installed version of the system for brand machines, which will be more reliable.

It's a bit of a hard question.

Will it be a hard disk, you can try it, put the hard disk from the new partition boot area to the back, don't use the original c position, or try a different hard disk.

There is also a paperback to try it, without the ghost system.

Let's learn from each other, and when we solve it, we will give an explanation. Thank you.

First, install it with a pure operating system disc.

Second, whether to mix memory, and if so, install with heads-up memory.

Finally, if it's a SATA hard drive, then map it to an IDE if you don't have an integrated driver.

When installing the system, you will be prompted whether to install the driver or not. Do not install all drivers first. See if you can get into the system.

If you still can't get in, then something in the system may be in conflict with your machine. Change to a clean version of the system. If you can get in, it means that there is still a problem with the previous driver.

It shouldn't be a problem to drive it with a driver sprite. I think the latter is more likely.

You won't install win7 under the memory of 256M, right?,The memory is definitely not enough.,So you can't get into the system normally.。

It should be that you haven't changed the mode in the BIOS hard disk, and the original system of the general brand computer has to be changed to redo. There are two settings for hard disk transfer mode: one is SATA mode (AHCI, enhanced mode); The other is an IDE (ATA, compatibility mode).

Does the Dell brand machine have its own protective partition for system recovery?

You first check whether the hard drive is good.

In DOS mode, use pure ghost to select and burn to see if there are multiple primary partitions.

Check whether the hard disk has bad sectors.
