Easy Tips To Fix No Signal Computer
Netgenz - Technology Computer and Internet | Causes of Monitor No Signal, there are many. It could be because the cable is not connected properly, the cable is damaged, the monitor to VGA is damaged, or the motherboard is damaged. For that, we must be able to analyze any damage experienced to repair it so that it returns to normal.
How to Fix a No Signal Computer
Previously you had to be able to distinguish between boot failure and no signal computer. No signal is a condition where the computer turns on but no picture appears, but a no signal message appears on the monitor.
While it failed to boot, mainly because of RAM. The only symptom is that the monitor does not display an image, but it is still on and there is no signal message.
1. Check Monitor Cable
First, try to check the cable used. Check the cable, do not let the installation loose.
Because in some cases, usually there are users who do not make the cable properly when installed.
This cable that is not properly attached can be accidentally detached when the monitor is moved. Then the result will appear with no signal message.

2. Replacing Monitor Cable
VGA Card connector cable to the computer, there are 3 types commonly used. VGA, DVI, and HDMI cables.
Then you try to replace the cable connector used to connect the computer to the monitor. If it returns to normal, it means that the cable is indeed damaged.
You can buy or borrow from a friend the cable you want to use. However, try to change the type of cable used if there is more than 1 port on the monitor.
This is to check whether or not there is damage to the cable connector on the monitor.
For example, if you usually use a DVI cable, then try using HDMI. Or if you usually use a VGA cable, then try using a DVI cable and vice versa.
3. Check Converter
As for some PC users, some have monitors with ports that do not match the VGA specifications.
For example, the VGA used only supports DVI and HDMI. But the monitor only supports the VGA port. Then the VGA card cannot be connected to the monitor.
To overcome this, a converter is generally used so that the computer user can run.
There are two types of converters commonly used. Namely an active converter and a passive converter.
Passive converters have relatively much cheaper prices than active converters. So most people prefer to use passive converters.
So, this passive converter generally does not always work normally.
However, from the sources of large computer forums, it is not uncommon for people to experience this kind of damage.
For this point, I have two solutions:
- Use a cable that each connector is the same. DVI to DVI, HDMI to HDMI, VGA to VGA. Because 100% sure way (as long as nothing is damaged). The price is also not too expensive.
- Try to use an active converter. Because most people prefer to use an active converter than a passive one (because the possibility of working is higher).
For the price itself, it is a little more expensive than a cable with the same connector. So, this active converter is just a second option
4. Check VGA (Graphic Card)
If the problem is not in the cable and monitor port. Then we have to check the VGA used.
Is it problematic or not. VGA itself is indeed a component that is easily damaged, even if only in certain situations.
For example, due to an unstable power supply. VGA temperature that is too hot, until the error with the overclock.
To check it, there are three solutions below:
Some processors have onboard VGA, some don't. Well, if you have an onboard VGA (Integrated graphics) try to use the onboard VGA first.
If your processor does not have an onboard VGA. Try to borrow a VGA card from a friend, to check.
Another solution, you can buy a cheap VGA card, whether used or whatever, as long as the compatibility is appropriate and still normal. But this is optional because it's a waste of money.
If the positive VGA is damaged, you can do RMA or service to the factory according to the VGA vendor you are using. But not all brands can do service to the factory.
There are unclear VGA brands, which of course only have a store warranty or distributor warranty, avoid this type of VGA. Better, buy brands that are well known.
5. Check Motherboard
In discussion no. 4 is the cause with discrete VGA (Dedicated Graphics). Then what about the onboard VGA?
If you are sure, that the damage is positive in the onboard VGA, then the solution inevitably has to be serviced or RMA is also the same as before.
If you want an easier solution, you can replace the motherboard with a new one. Or you can downgrade to get a cheaper price.
But if you are really sure that the onboard VGA is damaged.
