Add a memory module The system fails to boot and an alarm sound appears

I guess the memory is not plugged in.

Anyway, the landlord's 4G memory still wants to be upgraded? There's no need, what's the system you're using? Unless you use a 64-bit system, it makes no sense for you to add 10 pieces of memory, and the most memory that can only be recognized under a 32-bit system is wasted.

There must be a problem with the memory you got here. Your 4G memory is enough, 32-bit operating systems support less than 4G, even if you use a crack to make it support, no matter how large the memory is, there is no need. If you sell that memory, you should be able to sell it for 150.

I don't know if it's a very tragic situation, that is, the memory module is plugged in backwards, but I estimate that the probability of this situation is very small, I have made this kind of low-level mistake before, and the result is that both the memory module and the memory slot are burned, fortunately, the motherboard is not burned! I don't remember if it was your kind of sound when it was plugged in backwards, you can check it to see if the gold finger of the memory module is black, if there is. It's tragic.

Theoretically, yes.

Maybe it's because your memory is bad.

If you buy it now, it is a new 260 yuan.

I don't know the old ones.

There's no need to get so much memory, 2G is enough, how big of a program can you run now? Do you work in meteorology and aerospace?

Units of memory? Let's switch back.

Your question seems to be difficult to take, because it belongs to the type of failure is not clear, so it is difficult to say it in one sentence.

I analyzed it, if it is turned off for a long time, it will be in this situation, then I think the only difference between the two is the temperature, the boot temperature is relatively high in a short time, and the temperature has dropped after a long time, so the temperature is not high enough when it is turned on again, so the alarm is called.

Since it is a memory alarm, it may generally be related to the memory controller, seeing that your memory should be an old computer, then the memory controller is basically integrated in the north bridge, so it should be the north bridge virtual welding, that is, the problem of the motherboard.

The other half of the possibility is that the temperature of the memory itself is not enough, that is, the problem of the memory itself is determined by a very simple way, don't unplug the memory next time you call the police, turn off the power and turn it on again, see if you can turn it on, if you can, it's the two possibilities I said, if you still can't, that is to say, no matter how many times you open it, you must unplug the memory to turn it on, and then say it.

From what is known, a=k +3 4sina-cosa=root:2sin(a+4)=root:2sin(k+=- root:2sink=0, so sina+cosa sina-cosa=cosa sina=1 tana=-1sin2a=sin(2k+3 2)=-1

Your system is not installed properly, or it has a loophole, it is not stable!

Maybe it's because of the dust. Is your case open?。。 Try to put on the lid.。 Or clean up the dust.

Hello, it is recommended that you choose the memory in the following order:

1. Original memory. You need to contact the after-sales service or after-sales service point of Dell headquarters to buy, which is generally high, but the stability and compatibility are very high, and there will be no compatibility problems.

2. The memory of the same model or brand as the original memory of the machine currently in use, ** is relatively low, the probability of compatibility is also low, and the stability is medium.

3. Other memory. **Low, but the probability of compatibility problems is very high, and the stability is also poor, prone to problems.

Dear, is there a problem with the RAM you added.

If the system does not have RAM, it will alarm and cannot be turned on.

Take a look at the previous ram.

After powering off, wait 30 seconds and replug it before starting it up.
