Video card problem causes the computer flower screen how to solve

First opened the case of the computer chassis, and will be installed in the motherboard of the original video card out, and then correctly inserted in other computers to work properly on the video card, restart the computer, found that at this time the display screen will still appear flower screen phenomenon. In order to further verify that the graphics card itself is faulty, or the corresponding slot of the computer motherboard is faulty, the author tried to install the original graphics card to the normal work of the computer, the results of the reboot system found that the original graphics card performance is very stable. By the time we get here, we can almost conclude that the recurring failure of the flower screen is related to the video slot in the computer's motherboard.

Next, focus the check on the card slot on the motherboard. Consider the motherboard slot caused by the failure of the two kinds, one reason is that the slot is relatively dirty, the bottom may precipitate a lot of foreign bodies, these foreign bodies may hinder the card's gold fingers and graphics slots can not be closely combined, resulting in poor contact, and eventually caused the flower screen repeated failure; Another reason is that the motherboard's video slot is affected by the frequent plug-in card the slot connector may be too loose, so that even if the graphics card is barely plugged into the corresponding slot in the motherboard, the card's gold fingers can not be stabilized with the slot, so that the display screen may still appear unstable display phenomenon. According to the above analysis, the author first to the motherboard slot inside the check, found that there is no foreign body at the bottom of the slot, and the author tried to insert the video card to the bottom of the slot, I feel that there is no obstruction, the graphics card can be easily inserted into the bottom of the slot; is not caused by a foreign body inside the socket. In order to check whether the slot connector is loose, the author after inserting the video card into the corresponding slot, and hand the graphics card to the sides of the slot gently shook, a shake after the author found that the graphics card is not only able to shake, and after shaking the graphics card "body" is obviously tilted to one side, so that the card's gold fingers can not be stable with the bottom of the slot, Reliable contact. Obviously, the repeated failure of the flower screen is caused by the loose interface of the video card slot; After the computer's motherboard is replaced, the computer's display screen will immediately display the contents.
