CPU and power supply problems, what is the phenomenon of CPU power supply circuit broken

Then you can use AMD's CPU, which is suitable for cartography floating-point arithmetic high, at a much better than the E2200.

The power supply of 350W is enough for the motherboard 790G, with an integrated graphics card with an HD3300 and also integrates 128M video memory.

ASUS's board is good, but the low-end is not as good as choosing another brand of CPU, AMD7750 (box), 458 (4400+, out of stock now), motherboard, Shuangmin UR790GX 499

Memory (any brand) 2g 115 (don't buy a fake, hehe) hard disk 320g Seagate 330 (to be boxed) That's all for the rest you choose by yourself Bring a cheap monitor 2900 can come down if it's better, at least more than 3000.

e2200 is roughly equal to 5000+ like this.

AMD's CPU words.

ASUS M3A78-CM I just had a similar problem.

I've seen that motherboard, and it's not bad.

Intel's E2200 I think the integrated graphics card is probably too bad.

Whether it's NFORCE's or Intel's own motherboard chipset, all kinds of rotten.

You can consider buying a low-end discrete graphics card, such as the 9500GT.

P5QL is recommended for motherboards

At present, the mainstream practice is: AMD's CPU with integrated graphics card, Intel's with independent graphics.

The power supply is ......Theoretically, the rated 200W is enough, of course, in order to be a little more abundant, reserve space.

It is recommended to buy a rated 250W, recommend Huntkey, Cooler, there is no technical content in this kind of thing, it is nothing more than cost and materials, don't buy too cheap.

intel e5200 480

2200 and 5200 are not the same as sixty yuan Now, it is better to use 08 Zhongguancun as the most cost-effective e5200].

Motherboard ASUS P5KPL—AM SE 450

RAM KST 2G 800 110

HDD ST250G string 280

Disc Drive Casual 130

Chassis (casual) 100 yuan + Great Wall 350w 150 yuan.

Many cases are actually worth about 80 yuan, and I will calculate them for you. The power supply is actually enough for 300w, but I'm afraid that you will upgrade and add things in the future, anyway, 300w and 350w are 30 yuan apart. It's better to match it with a bigger one.

Keyboard and mouse Double Delphinium 60

1760 yuan.

The host of the integrated display is less than 2000 merchant profits, and I control it at about 120 yuan.

I didn't give you a stereo, and after I bought it, don't forget to ask the boss for a headset.

Don't buy ASUS for computers around 2000, ASUS's low-end motherboards are not as good as channel goods like rainbows... Power supply Ah, just take one, this set of configuration power consumption is not much higher...

Does an ASUS board have to be good? I don't feel it! We recommend that you configure it.

About 1900 yuan, what is left to choose yourself!

Introducing: The Intel E2200 and AMD4400+ you mentioned are not easy to find! **It's not very cheap, and the performance can't be compared to the 7750!

300w thinking you'll change your mind.

If the power supply is insufficient, the power supply will be unstable, it will crash, shut down, blue screen, etc.

1.The power adapter (charger) is broken, resulting in no power supply to the computer, but the computer battery supplies power to the motherboard for a short time, use a multimeter to check the voltage at the output plug of the power adapter, if the voltage marked on the adapter is too different or there is no voltage, replace the power adapter to try, if the output voltage of the adapter is normal, check it according to the following.

2. If the voltage difference between the electricity of the computer is too large or there is no voltage, try to replace the power adapter, if the output voltage of the adapter is normal, check and deal with it according to the following.

2. The power interface of the computer is not in good contact or damaged, when the adapter is normal, there should be a power indication and charging indication when plugged into the computer, if the computer is not displayed when plugged into the external power supply, it is a problem with the power interface or the power control of the motherboard, and it can only be sent for repair.

3. The motherboard has a short circuit and causes the power supply to protect the shutdown, this situation is the most serious, and the probability of replacing the motherboard CPU is greater, and the reason for this situation is that the computer fan is bad and causes heating and does not shut down.

4. If there is a spare battery, you can change to a normal electric battery to try to turn it on, so that you can judge whether it is a problem before the power supply of the host or after the power supply. If only the power adapter is broken, it is the easiest, you can replace it, and other faults can only be tested and repaired by a professional repair shop.

Detect the CPU power supply.

The CPU circuit of the motherboard mainly provides the conditions for the CPU to work. It uses a switching power supply circuit, which is mainly composed of a power control chip and an inductance coil.

MOSFETs and capacitors are formed into barriers. A faulty CPU power supply circuit will cause the CPU to not work and the computer to fail. Its faults are mainly due to damage to the MOSFET and capacitors and power control chips.

When detecting, first detect the resistance value of the 12V power supply socket to the ground, which is normally 300-700 ohms. This normal resistance value indicates that the upper tube of the CPU power supply circuit.

normal, otherwise it may be broken down.

Then measure the CPU power supply voltage, the normal value is, this voltage is not normal, measure the resistance value of the CPU power supply circuit FET to the ground, the normal is 100-300 ohms, if the resistance is normal, the spring will be destroyed.

3) Then measure the CPU power supply circuit chip output power simple buried voltage, generally, if it is not normal, then measure the pole signal of the chip, the normal is 5V, this normal and then test whether the power supply voltage is normal, generally 5 or 12V, if these two are normal, the chip is damaged. If the power supply voltage is normal after replacement, but the CPU still does not work, it is the i0 that is broken, replace it.

First, it's complete nonsense! If CPU performance could be reduced in this way, Intel would have gone bankrupt a long time ago! If it is said that due to the poor contact caused by the severe oxidation of the contacts, it is possible that the CPU has a problem in operation, but this situation is basically impossible to happen, and the human contacts are gold-plated.

Second, I don't know what model your CPU is, Core has an automatic turbo frequency function, that is, when running larger programs, it will automatically improve performance, and when browsing the web, it will automatically reduce the frequency to run, which is more energy-saving, and after the frequency reduction, the operating temperature will naturally drop, so that the CPU has a longer service life.

Third, whether it is the circuit board, coil, line direction, etc., the high-quality power supply is optimized and manufactured through layers of optimization, and there will be no problems you are worried about, unless it is a copycat power supply.

Hope it helps.

The first problem is a joke, the pins on the motherboard are all somewhat slanted (more curved than skewed!). ）

The second question is whether you feel that the usage rate is high, or whether the usage rate is really high, which is completely different things! Psychological effects?

The third is not afraid to move up and down, left and right, but it is best not to move the old brand, miscellaneous power supply (some non-miscellaneous brands in order to save costs) cable is soldered on the PCB board in the power supply, good in addition to soldering there is a wire cutting device, and the best is the modular type! (Don't tell me your power supply model, I only know a few models with pinched wires), so it's not good to move often, and it's easy to open and weld (naturally hanging down in the chassis, and the natural swing should not have much impact!) It's best to secure the cable (with a nylon cable tie or even with a cord)!

First: they tease you, and the CPU also needs to be removed and cleaned up, especially after you have used it for a few years. There will be dust on the contacts. When the time comes, you won't be able to turn it on! The pins inside that motherboard are all tilted. I don't know why. Haha

Second: If the cable is not plugged in, the computer will not turn on. This is a bit of a psychological effect, right???

Third: The power cord, the ones that are not used can be tied up with that small circle. There's no need to worry about them.

Just plug everything that should be plugged in. However, note that those cables do not touch the CPU fan and the graphics card fan. Otherwise, it's dangerous.

It is easy to burn.

CPU is to remove and install it is to paint that lamb, that is, something like glue, in addition, the computer should be set to select the power mode to, always on, XP setting is the power setting of the screensaver ** on the desktop, so that the computer is fast, the power cord is very tight, and it is pulled open with great force, no problem.

Your worries are all superfluous psychological effects.

First, no, the 1155 motherboard is not oblique. The second point I don't know, the third movement doesn't matter.

Tell you that it is impossible to drop.

The computer can't be turned on, the screen doesn't light up, and the value is not displayed when using the test card.
