Many desktop users have experienced this: computers are well used, and suddenly there are coloured stripes, snow spots, images that are confused, which is what we often call a flower screen. Sometimes it's good to shake the monitor line, and sometimes it's always flashing, which gives you a special headache。
When most people look at the screen, the first reaction is that the graphic card is broken and they have to pay for hardware. In fact, there is no need to panic at all! The desktop screen is mostly a problem of poor exposure or wires. There are not many cases of real graphic card damage that can be solved by simple self-censorship。
First of all, the most high-frequency questions: loose, ageing video lines。
The hdmi, dp, vga video lines on desktops, long-term placements, light moving motor boxes, cleaning, etc., are easily relaxed. Line contact is unstable and the transmission of video signals is intermittent, resulting in the direct appearance of a screen, flash screen, snowscreen。
You can cut the power first, pull out all the video lines on both sides of the monitor and the mainframe, and re-plug them tight. If there is a back-up line in the home and one test is changed, many of the screen problems can be restored immediately。
Second common cause: poor exposure to independent graphic cards。
The desktop case is thick in ash and long-term vibration, and the gold finger of the card is easily oxidated and loose. The computer is running normal, operating with heat and starting with screens, which are essentially a graphic card contact。
When the power is completely out, the side panel of the machine is opened, the graphic card is gently removed, the gold finger position is wiped with rubber, the stains of oxidation and dust are wiped out, and the slots are re-established. Reload, most of which is intermittent。
The third reason is that the tank is too hot。
In the summer, the temperature is high, or the fans of the aircraft are not turning ash, and the temperature of the graphic card is soaring that the images appear to be abnormal and the screen of cardon. It is possible to check if the case fans, the visible card fans, are moving normally, clean up dust in a timely manner and ensure that the case is ventilated。
A simple way of judging is to put the monitor on another host or notebook, which is a problem with the screen; the screen is still a failure of the monitor itself。
If the above method is fully checked or continues to be severe in the form of screens and images, the probability is that the graphic card chip or monitor hardware has been damaged and it is recommended that a specialized maintenance test be found to avoid the self-dismantling machine causing further malfunction。
Remember, desktop screens are wired, re-introduced, heat-scattered, and don't change hardware for iq tax as soon as they come up
