The person who can answer this question must be an IT expert? I hope that all passers by point to th

intel 815e/ep; tualatin rev22 ;Award Modular BIOS, 5 PCIs, 3 memory sockets, red motherboard, produced in 2001. There is an onboard graphics card, but there are separate separate graphics card sockets, there are three SD memory sockets, and the board color is red. The motherboard is second-hand, so I don't know the brand, and I can't find it with software, so I can't flash the bios

My current CPU is now yes, if the last piece or yes, is the difference in speed reflected in my hosting big.

Through your description, your motherboard is first judged to be not a brand motherboard, first of all, the brand motherboard will be marked on the main chip, the brand, model, generally 815 810 series motherboards are red and do not pay attention to the brand, which is generally an OEM product. It is recommended that you do not need to upgrade. There is no significant improvement in performance.

It is recommended to upgrade the graphics card. Or increase the memory to improve your PC's performance.

**It varies across the country, and **200 in Huai'an, Jiangsu

**240

Your next CTBIOS, you can look at the motherboard BIOS model, or turn on the next line of English, maybe award*** or something, copy it down, and search on the Internet.

1G-> actually doesn't change much, so there is no need to upgrade.

You must be able to see the brand and model on the motherboard, as for the speed, if it is not a large software, it is basically impossible to see, and it can only be bought in the second-hand market on the market, one or two hundred yuan.

When the BIOS model is turned on, you can see that many motherboards will also display the manufacturer's logo when they are turned on. I really can't find a model number from the Internet to find a chipset like a slot like a board and flash it with the BIOS file on your machine. Don't use this casually!。

The speed of change does not change much, and it is almost impossible to feel it without testing the software.

There is no need to upgrade the CPU, in fact, the performance is good, it feels better than the P4 plug, if you want to greatly improve the performance of the machine, adding a graphics card is the right thing.

I don't think it's necessary, it's a waste.

It's better to make do with it

Every day is different, and each boss sells differently.

1. I'm not a master, but I have encountered more failures.

2. The red light of the indicator light is the hard disk light, and the red light means that the hard disk data is being read.

3. Unplugging the hard disk data cable can solve the problem, it may be that the data cable or interface is not in good contact, change the port or cable (there are multiple SATA interfaces) to try to solve the problem.

4. The first task of feeling, suspecting, or indicating that the hard drive is faulty is to back up important data, and wait for it to be completely broken.

5. After the data is backed up, use the hard disk life detection software to check the health status of the hard disk, and pay attention to whether there is any abnormal sound of the hard disk or data loss for no reason.

6、In addition to these,It can only be the reason for the power supply and the motherboard,The screen stop may be the cause of the system (the mouse is still moving),If you can call up the task manager, it is not a crash,If you can't, it's a hardware failure,And the problem of the motherboard and power supply is more difficult to solve by yourself (except for replacement),Try them one by one。

There are two possibilities for this, one is the hard disk problem, so after you unplug the hard disk cable, restarting the hard disk can solve it There is another possibility is the power supply problem If you just encounter such a thing when you start up, most likely it is a power supply problem You can test the hard disk in the next software, if there is no problem, it must be the power supply If it is a power supply problem, you must find a way to fix it as soon as possible, otherwise your hard disk will be finished soon

You can use HD Tune to check if there is a problem with the hard drive.

3x5=15

But carry = 13

5-2=3 Everybody is 3

The base is 126x3=18

So 6x3=16

Honest communication. Integrity, professionalism, efficiency and unity.

This carry counter uses every 12 digits.

So 3*5=12+3=13

So 6*3=12+6=16

Nima, this problem is not described correctly, it is not superimposed on reality at all, 1 I choose A

2The first one from the perspective of single-chip microcomputer is to choose A (the reason why choose A is that you have not used an Android phone, the previous version of the mobile phone parameter memory expresses RAM, ROM is internal storage not memory, you can refer to the computer configuration parameters).

Big brother's three questions are basic common sense: the basic unit is bytes (b), this 01 is of course (bits), in fact, there are contradictions in this problem, it can also be said the other way around, the processing data is of course eight-bit binary, that is, bits 0 and 1, and when passing and transmitting in the form of bytes, the documents we see are all in large and small bytes, alas.
