Ask the master to help solve the computer problem, and everyone who understands the computer can hel

Looks like you're having a problem. Wrote so much. Sympathize.

Let me give you a suggestion.

First of all, if you have done the system many times, there should be nothing wrong with the system aspect.

Solve it from the hardware, 1: Check the keyboard You say that the keyboard is not stuck, it does not prove that the keyboard is good. There are circuit boards and chips in the keyboard If they are disordered, there will be strange problems, it is recommended to borrow a keyboard to experiment.

Exclude keyboards. 2: RAM, you have two RAM. You only plug in one experiment under Swap Slot separately to exclude memory.

3: If the above does not solve the problem of checking the hard disk, including bad sectors and bad sectors, you must do it under DOS and check it after the low grid. If there is a spare direct replacement, the order is placed.

By the way, let's see if there is any problem with the jumper sequence. There is also a hard disk data cable with ** and poor contact.

Exclude hard drives. 4: Check the motherboard.

Carefully check whether there are burnt parts (after all, it has been a long time) and whether the capacitor is bulging and leaking. If there is none, the battery will be turned off and cooled for 1 hour. Fully discharged and cooled.

If you can flash a new BIOS (dangerous operation, please be careful).

5: The possibility of CPU is not none, but it is very low, even if it is broken, there is no cure, and it can only be replaced. So the final check (software can be used).

Hope it helps.

It should still be out of the keyboard. Check for keyboard and mouse driver issues first, and then check for unbouncing or sticky keyboards, as if holding down some kind of key combination. Then there is a short circuit in the wiring or interface of the keyboard.

Try it with a different keyboard or graphics card, if it doesn't work to reinstall the system or change the keyboard and mouse, it should be a graphics card problem.

Personally, I think either the memory is broken or the motherboard is broken!

1. That's what it says in book b.

2. It should be an access and output device.

3ACROM and RAM are two models of computer memory, ROM represents read-only memory, that is: it can only read out information, can not write information, the information in it is still saved after the computer is turned off the power, and it is generally used to store fixed system software and fonts. RAM represents read-write memory, which can be used by any storage unit for read or write operations, the information in it will not be saved after the computer is turned off and the computer needs to be reloaded when it is turned on again, usually used to store the operating system, various running software, input and output data, intermediate results and exchange information with external memory, etc., we often say that memory mainly refers to RAM. 4b
