The monitor doesn t show up when the computer is turned on, but the program is still running normall

Theoretically, if the graphics card is broken, it will alarm the boot.

So the problem is unlikely to be with the graphics card.

Suggest: Find a computer and test your monitor.

It's basically a graphics card issue, so if you have a different monitor, you can swap it out and try it.

That's because there's something wrong with your graphics card, it's because it's been used for a long time and is old. It is recommended to use an eraser to wipe the gold finger after unplugging. It's also possible that the temperature of the graphics card is too high, it's summer, the case temperature is hot, it is recommended to open the case cover, mine is used like this, it used to crash, but now it won't.

Same as my question the day before yesterday, my final result was that the graphics card was broken, and my machine was performing just fine, and the login XP sound was also there, and I was able to shut down with the keyboard.

The specific solution is as follows:

1.Check whether the power and restart buttons have a physical failure, the most common is that you can't get up when you press it, any of the two buttons has this problem, which can cause the computer to fail to boot normally. The only solution is to send the chassis for repair or replacement, because the chassis is integrated into the chassis, which is difficult for ordinary users to repair.

2.Open the case, unplug the motherboard BIOS, wait for a while, and then press it again to see if the computer can run normally.

3.Unplug all the connection cables between the motherboard and the chassis, and touch the power control pin of the motherboard with a screwdriver (because there are many pins, please refer to the motherboard manual for the confirmation of the power control pin, don't touch it, it will burn the motherboard), if it is turned on normally, it proves that it is a problem with the boot and restart buttons of the case. The workaround is the same as above.

4.Unplug the power supply and the data and power cords between the motherboard, optical drive, hard disk, floppy drive and other devices, unplug all the devices on the backplane of the motherboard, such as the display button, network cable, mouse, and keyboard, and dry the dust on the power socket and power plug of the motherboard, and then plug it back in and turn it on. If it can be turned on, plug in the devices one by one to confirm the source of the fault.

After confirmation, update the faulty accessory to resolve the issue.

Step-by-step test

Part 1: Your system disk can't be started? If all system disks can't be started:

Find a good system disk, restore the CMOS settings to factory settings (that is, the default settings), and then set it to a disc to boot, and try to get up.

Remove your network card and other standalone cards (you're not in the brand phone of the warranty period, right?) There is an integrated graphics card, remove the discrete graphics card, reduce the memory module to be able to boot (as little as possible), and try to install the system after cleaning up the dust.

Check whether there is any problem with all cooling systems (fan speed, silicone, heat sink, contact), etc., and borrow a power supply to replace it.

After turning on the power, discharge the handle (touch the iron or wash your hands) to feel if there are any hot chips on the motherboard.

2. If the system disk can be started, pay attention to:

This is the case if the driver is not suitable.

After the latest virus database update of Norton Antivirus released on May 17, the key system files of the Windows XP system will be removed as viruses, and the system will be paralyzed after restarting. He also said that the accident was only for network computer users who installed both Windows XP Chinese Simplified Chinese version of the operating system and Norton antivirus software, and Norton upgraded the latest virus database that the antivirus software would isolate and remove 2 important system files (mistaken for virus files, thus causing the system to crash. It is recommended to go to the clove fish to get an eset to use.

Some software can also cause this, such as a certain version. It is recommended to go to the big software station.

The voltage is unstable or the hard disk is bad (damaged drive).

It may be that the graphics card in your host is too dirty.,It might be good to take the host apart and clean it.,I've also encountered this kind of situation.,That's how it was repaired.

It's possible that the graphics card is broken. Try changing the graphics card, or see if your computer has an integrated graphics card. Plug it in and try it. Or maybe there's a memory mismatch, it's just a problem I've had before.

Depending on how long it runs, antivirus is recommended. Check the graphics card. Drive.

First of all, the monitor does not display, is it even the power light of the monitor? If the light of the monitor is also off, it is a problem with the power supply of the monitor, check whether the power cord connector of the monitor is loose. If the light of the display is still on, this is also divided into two situations, generally when there is a signal, the indicator light of the display is green, and when there is no signal, the light is red.

If the light is green, it means that the host has a signal to the display, but the display does not display, which is the problem of the display itself; If the light is red,That's no signal,That may be a problem with the data cable connecting the monitor to the host,Check the interface at both ends of the data cable or replace the data cable to try。 If it doesn't work if you change the data cable, it's a problem with the host.

For example, when you are listening to a song, the display is not displayed, is the song still playing, can you hear the sound? If you can, the host is basically fine, just find the reason on the data cable and display. If the songs are stopped, it's a crash, the host hardware.

Let's find out what went wrong first... The problem of the host hardware is not clear in a word...
