Know the computer experts, why my computer boot screen shows no signal detected, the graphics card fan also turned, all fans will turn, how can not it? My machine is such that the memory I pull out the re inserted no, not inserted nor change the hole or that I put on the host connection screen off the display in fact please plug the cable plug, on-line signal is not detected, that line is good, what this is all about?
You plug in the cable that connects the screen line to the point, try, or restart
Graphics card damage, coupled with the output of integrated video card, such as good, it shows that the video card is broken
I encountered this problem last time because the graphics card is loose, I plug in again, with memory to solve, my friend encountered this problem is because the video card burned, changed graphics card to solve
The first point is that the video line is broken, so the signal is not transmitted to the displaySecond point, you have to add independent graphics card, plus, the host video line to plug in the following socket, not aboveAt third, one of the components of the motherboard is broken. Try it at the first two. No problem. It's third.Try another host
(first the computer power off), this is the motherboard startup error, is likely to be caused by poor contact components, leading to the motherboard can not start properly, and graphics cards have nothing to do. Pull out the graphics card and memory, and clean the contact area with paper towels or rubber. It is better to use the hair dryer to blow off the dust on the motherboard. (this is a small chance, but it doesn't rule out memory gold finger oxidation). Unplug the motherboard's battery and wait 1 minutes to put it back. Try to make sure that the pressed parts try to get in touch with it. Still not, if there are other power supply, try another power supply. If successful, speed into BIOS, restore the optimal settings.
