The graphics card is turned on and the DOS status is blurred, and it cannot enter the XP system

1: This is normal, I've done it before, it's very violent, hehe, I changed the BIOS of HD3850 to HD3870, so the frequency is too high, and the screen is blurred under Windows DOS. You can change the BIOS and ask someone from the repair station to help you fix it.

2: There may also be a problem with the memory, because the memory problem will not only lead to a blue screen, but also a blurred screen, many people think that the blurred screen is the fault of the graphics card.

I am a professional repairer of motherboards and graphics cards. ls Some people say that the blurred screen is not necessarily caused by the graphics card, which is right, the graphics card, memory, and motherboard are all possible.

But depending on what you're talking about, 90% of the graphics card GPU is turned on. Because the 7600gs NVDIA has admitted that there is a quality issue.

Sometimes it will be good to rule out the BIOS problem, and the BIOS problem cannot be good for a while and bad for a while, it should be that the GPU is soldered, resulting in no contact when the tin dot is contacted.

It is recommended to send it for repair, if it is expensive, replace it. This kind of repair is generally easy to 2nd RMA again.

The way they repair is generally reflow. Not insured

The above are true, and if you don't understand many professional words, you can check baidu

May I ask you whether you are a desktop or a notebook, if the notebook looks at your description, if you rule out the driver problem, it may be that the LED tube is broken, if it is a desktop, the screen may be a graphics card failure when you turn on the DOS, it may be a problem with the CPU, don't think I'm talking nonsense! Find someone to overhaul it, you don't think you can get it right.

Addendum: Have you tried reinstalling the system? Could it be that the system is not installed properly, or the driver is not installed properly.

I asked a friend who was doing chip repair, and said that it was also possible that there was virtual welding on the north and south bridges, and I tried to add welding.

It's basically a problem with the graphics card, and if the main version has an integrated graphics card, you can try to plug the monitor into the integrated socket, and if there is still a problem, it's a problem with the main version.

It should be that the driver is not installed properly.

The reason for the blurred screen of the computer is generally a hardware problem, and it is estimated that reinstalling the system will not solve the problem, because the screen is blurred when entering DOS, so it must have nothing to do with the system.

It is certainly related to the root display, three possibilities.

First, your VGA interface is loose, that is, there is a problem with the connection between your computer and the monitor, you see if your graphics card is loose, and then see if the cable is loose, you can use the monitor, shake the position of the graphics card with your hand, and see if the screen has changed.

Second, the quality of your graphics card is good, you can only change it, take it to the place where you sell the computer, and let them change it to Ziyunmin to try.

Third, check your refresh rate, but this may be smaller.

Anyway, it's definitely a problem with the graphics card. Of course, it is possible that there is a problem with the display, but the probability is very small. Quietly.

You turn the color down and try it. This may be a certain color of the DOS that does not support your graphics card. For example, the lap bend only supports 256 colors. 16-bit.

If you change the 32nd place, he spends it.

This is generally caused by the poor damage caused by the poor contact between the graphics card and the motherboard, take it down when the power is off, stand up to the metal place, plug it in if the problem is not solved, you can only deal with it or repair it, it is recommended to repair or replace it, don't disturb the dust motherboard, and it costs more money.

Maybe it's a quality issue

You can try to change your driver to see if this is the case, if there is a warranty, you can go and change it, this kind of graphics card, it is easy to break,
