The diagnostic card shows what D4 07 means

The motherboard test card shows D4, which means that the memory test failed.

Memory testing refers to the multiple inspections that the memory undergoes during the production process, including welding inspection, PCB appearance inspection, functional inspection and overall appearance inspection.

On the other hand, it also refers to software memory testing. It also needs to test the usage of resources such as the maximum memory of the software to prevent the software from using more resources than the limits of the system. It is also necessary to test the software behavior of system resources in extreme cases, such as when the system memory resources are consumed by other applications after the program runs for a long time.

The motherboard test card shows D4, which means that the memory test failed.

Use an eraser to wipe the contact points of the CPU, there are aging places, the CPU is gold-plated, and the plugs or electric shocks of the motherboard are also gold-plated, but now some motherboard manufacturers in order to save money, the amount of gold plating is obviously insufficient, if the motherboard is not deformed, you can try it with a different CPU, there are many models of the detection card, no one can say that it is not good, and the detection card is not completely accurate, replacement repair and virtual point detection is the last word.

The main reason why the display has no signal is that the memory and graphics card are in poor contact, take off the memory and graphics card, erase the gold finger with an eraser, and look again.

d4 or the memory has not been changed to see.

1.The power supply is insufficient, whether the power supply is enough for 300W, see how much W is marked on the label with +5V.

2.If there is a compatibility problem with the memory, just plug one to try, and conditionally replace the brand-name genuine memory test.

3.There is a problem with the graphics card, pay attention to the driver of the graphics card to try to change the version, it is best to replace the graphics card and try again, the motherboard of NF2 has the phenomenon of insufficient AGP power supply, you can consider adding AGP power supply appropriately in the BIOS.

4.The hard disk has bad sectors, this possibility is small, and the general installation system will not be able to continue.

Significant electron migration of silicon chips occurs during long-term overclocking, as is the case with the u of Barton's core.

6.The power supply circuit of the motherboard is unstable, check whether the capacitor is blistered.

If there is a problem with memory, please check the memory, or use a leather wipe to pat the gold finger of the memory. Then reinstall it.

Key suspicions:1The power supply is insufficient, whether the power supply is enough for 300W, see how much W is marked on the label with +5V.

2.There is a compatibility problem with the memory {only plug in one to try, and conditionally replace the brand-name genuine memory test}3There is a problem with the graphics card {pay attention to the driver of the graphics card to try to change the version, it is best to change the graphics card and try again, the motherboard of NF2 has the phenomenon of insufficient AGP power supply, you can consider adding AGP power supply appropriately in the BIOS}

4.The hard disk has bad sectors {this possibility is small, and the general installation system will not be able to continue} long-term overclocking and serious electronic migration of silicon chips {the u of the Barton kernel has this phenomenon}6The power supply circuit of the motherboard is unstable {check whether the capacitor is resistant to reed bulging}

The art slippery Wang group has achieved success, points.

55, there is still a need to shout from the next level.

Integral. It seems that you are not very familiar with the diagnostic card, if the diagnostic card shows 00 then it means, CPU

Without a job, there are two possibilities, one is.

Problems with the CPU itself (which is very unlikely); One is.

Mainboard. There was a problem (the possibility of the time is very large). It is recommended that you detach your CPU and put it on another motherboard to give it a try, and the problem will be clear at a glance. In my judgment, there should be a problem with the hosting! You can try.

An MSI motherboard (computer malfunction boot black screen, monitor no signal, monitor etc. bright yellow letter orange) My diagnostic card shows (the front 0 is missing half, that is, half of 0, I think it is 00, the back 0 is full, is this 00? What is the problem? Thank you...
