Exclamation mark appears in graphics card miner

1. may be caused by the driver is not completely installed, or the driver version installed does not match the system

2. re install other driver versions, or ask the customer service of the graphics card brand if they need to install the driver for mining and switching< br />

The yellow exclamation mark on the graphics card means that the driver of the graphics card is not installed correctly, and the driver of the graphics card needs to be re installed

the installation method of graphics card driver is as follows:

1. Find the "start" item in the lower left corner of the computer desktop and click to enter

This is because the driver of the graphics card is not installed properly or the driver of the graphics card needs to be updated

here, take win 10 operating system as an example, the methods to update or install the graphics card driver are as follows:

first, find "this computer" on the computer desktop

This is e to the incompatibility between the graphics card driver and the system, or the old version. Just update the graphics card driver. The solution is as follows

1. Re: radiated emission (100k ~ 2.7g) radiated emission: radiated disturbance test

2. Ce: concted interference Ce (150kHz ~ 108MHz): concted disturbance test

3. Rs: Radiated Immunity: Radiated Immunity Test of radio frequency electromagnetic field

4. CS: concted immunity: Radiated Immunity Test of radio frequency field inced concted disturbance

5 EFT: transient pulse interference: Electrical fast transient pulse group immunity test

6. Dip: voltage sag: voltage sag, short interruption and voltage change immunity test

7. ESD: electrostatic: electrostatic immunity test

8. Surge: immunity surge (impulse) immunity test

power line inction applies switching impulse voltage to low voltage winding of power transformer, It is a test to make the insulation of high voltage winding of transformer withstand overvoltage test by electromagnetic inction

the voltage waveform applied in the test is a kind of waveform generated by simulating the switch operation or fault in the power system, which is called switching impulse voltage wave

according to the Chinese power instry standard, the switching impulse inced voltage withstand test can be applied to the substation site to test the insulation of power transformer

the power line inctive contact generator is a common basis for simulating the interference of power line or electrified railway system to adjacent communication lines and the direct contact between power line and communication line

extended data :

EMC includes two major items: EMI (interference) and EMS (sensitivity, anti-interference)

EMI test items include: re (radiation, emission)

1, Ce (concted interference)

2, harmonic (harmonic)

3, Flickr (flicker)

EMS test items include: ESD (static)

1 EFT

2, dip

3, CS

4, RS

5, surge

6, PMS

classification:

I. EMI (electric magnetic interference) - electromagnetic disturbance test

main contents of EMI test:

1 The purpose of this test is to detect whether electrical procts can work stably in electromagnetic environment, Not affected

1, ESD - Electrostatic immunity test

2, RS - RF electromagnetic radiation immunity test

3, CS - Concted disturbance immunity test inced by RF field

4, dip - voltage sag, short-term interruption and voltage change immunity test

5, surge (impact) immunity test

6 EFT - Electrical fast transient burst immunity test

7, pfmf - power frequency magnetic field immunity test

8, stray definition: refers to the radiation on discrete frequencies (i.e. far end radiation) except carrier frequency and sideband and adjacent channel caused by normal molation and switching transients when molated by standard test signal. Stray radiation can be divided into conction type and radiation type according to its source

10. Stray radiation: stray disturbance caused by the enclosure, structure and interconnection cable of the test equipment. The test conditions are preferably carried out in the anechoic chamber or outdoors

1. you can go directly to the vehicle management office to register for driving test

2. from April 1, 2016, you can apply for a driver's license at the vehicle management office, and you can make an appointment for the test after you pass the application! As for the self-taught direct test, it means that when learning driving skills, the designated area is provided by the Ministry of transportation, and the qualified accompanying personnel lead the self driving practice

3. the independent appointment test is to agree that the driver's license subject test can not pass the driving school appointment test. According to the regulations should go to the vehicle management registration, should not go to the driving school registration. Self taught direct examination of the examination application need to be self about the test! As long as you can drive, you can make an appointment on your own

< / OL >



extended materials:

1. from April 1, 2016, the notice on self taught direct examination point of motor vehicle driver's license will be officially implemented. After passing the subject one examination, self-taught personnel can get the learning driving certificate and special signs for learning to drive for free according to the regulations, and then they can go on the road for driving training according to the route and time specified by the traffic control department of public security

2. after the implementation of the new policy, if self-study personnel commit traffic violations under the guidance of on-board instructors, they will be punished; Whether the self-taught personnel have obtained the learning driving certificate

3. identity certificate of the applicant:

4. (1) certificate of physical condition issued by medical institutions at or above the county level. Those who apply for a small automatic passenger car for the disabled shall submit the relevant physical conditions issued by a special medical institution designated by the Provincial Department of health

   (2) Article 25 If the certificates and certificates submitted by the applicant are complete and conform to the legal form, the vehicle management office shall accept them and examine the application conditions of the applicant for motor vehicle driving license according to the provisions. For those who meet the application requirements, the vehicle management office shall arrange an appointment for the examination according to the provisions
