Question:

Why does the computer monitor show no signal?

The boot after the CPU fan, but no "drop", but also for the computer display no signal, what happened? Just since the last from the newly installed system after a few days on this issue, what's going on?

Answer:

Unplug all the hardware in the chassis and plug it in again, because it's often a matter of hardware contact. Of course, don't forget to see if the plug plugged into the motherboard is plugged in.Our company is an old machine, graphics cards, network cards, sound cards are still independent. Often appear such problems, one is like you, I am so resolved, of course, maybe you are integrated.
Estimated that your video line appears the aging, the video joint place, the contact is bad.Suggest changing a display, you can also discharge the motherboard or the motherboard battery down five minutes, and then plug in try.
1. Remove the small battery on the motherboard and reinstall it in a minute.2, boot, listen to the BIOS alarm sound, and accordingly determine which hardware problems.Don't know how to judge, to Baidu search "BIOS alarm" can.To be sure, the hardware problem. Personal feeling is more than graphics cards. Not plugged in, or the video card is broken. I wish you weren't tight.
You pull out the memory, clean, try to plug in, or else some of the main console loose or dusty, and then can not install a system to try. Not yet, that is, the host hardware inside is broken, sent to repair the computer where to repair it, do not want money, ha ha, some problems can not be solved software, but also hardware processing, every approach
Yes, there are many reasons! This is the usual maintenance computer often said "not lit."1 if you just can boot into the desktop display, can hear the voice that the host hardware is no problem, may lead to the display resolution is too high can not be displayed, then press the F8 key at boot, select safe mode to reduce the resolution is good.2. if there is no signal on the boot, listen to there is no alarm, and some may be caused by graphics cards or memory loose, dial the graphics card or memory plug in again, then boot try3., if there is no alarm sound, then there may be a motherboard or CPU problems, but the general CPU rarely out of question, the possibility of the motherboard is more likely4. power supply is also likely to cause this phenomenon5. find the motherboard CMOS jumper test6., if there is a motherboard fault detection card, it is easier to find out whyMore than 7. methods can not be solved, then, it is best to use the maintenance of computers, commonly used replacement method, to the friends where to borrow graphics cards, CPU, memory and other hardware, try to know what the problem.
