The red signal is for the motherboard which indicates it has powered on. It has nothing to do with the video card.

In the no signal problem, please make sure that the video card is firmly pressed on the its slot.


Detach and reattach your memory [RAM] or put it in a different slot right beside it.

K8NF4G MOTHERBOARD IS NOT WORKING


Your Video Card (Graphics Card) is probably bad. To isolate the problem connect another monitor to the computer. Borrow a monitor from a neighbor, friend, relative or co-worker and connect it to the computer. If the Borrowed monitor displays the same NO Signal Message then your video card is bad. If the Borrowed monitor displays and works correctly, then your original monitor is bad. The fact that your monitor displays the No Signal Message on it shows that the monitor is ok.

If you have a laptop, the video will show on most systems when you reboot without you having to do anything. Some systems will require you to hit the FN (Function key) + F1 thru F12. Hold down the FN key then hit the correct key for displaying on the monitor (F1 thru F12). The correct key will normally have CRT/LCD on it or it will have the icon of a display.

What should I do because it says no signal input


Sounds like your video card or monitor is bad. Most likely it's the video card because if it was the monitor the No Signal Input could not appear on the screen. To isolate the problem try connecting another monitor to the computer. Borrow a monitor from a neighbor, friend, relative or co-worker and connect it to the computer. If the Borrowed Monitor displays ok without a problem then your original monitor is bad. If the Borrowed monitor has the same issue of No Input Signal as your original monitor, then your video card inside the computer is bad.

This is going to sound vague, but currently a friend and I are working to get this desktop PC working that has a KN9 SLI motherboard installed on it. Currently, the issue is: The computer turns on, a red...


Try checking the jumpers on the motherboard. A lot of the SLI compatible boards have jumpers that need to be configured properly. You can find out the positions by checking the motherboard manual. Are you using an SLI capable video card or is the video onboard? I just ask because I had the same problem once while trying to install an SLI video card. I had no picture on the monitor and I couldn't figure it out for the longest. Finally I found the answer in the motherboard manual and it turned out to be a jumper that was set wrong. Hope this helps.

Hello I have a problem, my motherboard g31-m7 no video, i picked up the battery, but the problem still there, how to solve this problem?


I don't know who recommended a CMOS battery to fix your graphics, but this = no.

1) You have checked the monitor cable, correct? If the monitor cable is removable, replace it with a known to be good one, for a test.
If the monitor cable is not removable, use a known to be good monitor, and cable for a test.

2) If you are using the Integrated Graphics of the motherboard, (OnBoard graphics), then the next test is to install a graphics card. If you have graphics now, your OnBoard (Integrated) graphics chipset is bad.

3) I find most of the time, (Like around 80% or more) that the Power Supply is bad.
Enough power to light LED lights, spin fans, (Or spin a few times, and stop), but NOT enough power to turn the Processor on.

A bad Power Supply is one of the leading causes of computer failure, right next to computer is dirty inside.

A) ALL of the LED lights being on at once, will use less than 1 Watt of power.

B) EACH fan uses 2 to 3 Watts of power.

C) A typical Processor can use 51 to 125 Watts of power. Depends on what Processor it is.

Here you can see a CPU Support list for the Biostar G31-M7-TE motherboard, and the wattage of the different CPU's,

http://www.biostar.com.tw/app/en/mb/cpu_support.php?S_ID=363

Again, you may have a bad Power Supply.
Enough power to light LED lights, and spin fans, but not enough power to turn the Processor on.

No Processor operating, No computer.
No computer operating, No video signal.
(No Signal)

Do you have a KNOWN to be good, compatible power supply to use for a test unit?

Acer monitor does not get signal every time


If anything try updating the video card drivers. That's what it sounds like, or the monitor is going. The next time the monitor fails to start, just unplug from the input and put back in. If it starts you are looking at a bad power booster on the board. You can also try pluging in another monitor or try that monitor on a different machine. This way you can eliminate which is bad. I had flat panels and crt's go on me and they usually start by this symptom. It shouldn't be the BIOS, if it's been working right along, same with the processor, it either works or doesn't, it's a monitor scenario.

COMPUTER WON'T BOOT UP


The possible reason why there's no signal on the mobo are, first of all it can be a problem with the video card and since you already tried replacing the video card and still no sigal so it means not the video card problem, you can also try to connect a different monitor if possible to check if its not a problem with the monitor and also a bad motherboard will cause this since the video card is connected to it and so if you already try a different monitor and still the same problem motherboard is the one that is bad....

Red Light


Hi Ivematthew,
Usually, that red light is simply an indicator that the mainboard is receiving a 5volt supply from the power supply and you must NEVER install or remove any mainboard components whilst this light is on. In fact, dont touch the instde if the case or the mainboard if this light is on.
If you are getting a no signal on your monitor, try turning off at the mains and pulling the plug out, then touch the metal chassis of the case BEFORE you touch anything inside the case.
Then carefully remove your video card and re-install it into the same slot, you can even do this a couple of times. Then try booting the system up.
Also, check that both ends of the video cable are securely connected and that the cable appears undamaged.
I have to ask, Is the system booting up?
Are you getting a single beep at the start of the boot or is your system beeping more then once?
If it is beeping more then once, count the length and number of beeps and go to the ASUS website where you can use the beep code to locate the particular fault the mainboard is signalling about.
Let me know how things go and email me if you are still having issues OK?

Ram problem..


carthi, I do not think the problem your having currently has anything to do with your memory. If your video card was integrated into the board I might agree there could be a problem with your memory but that is not true. Your video card is an AGP8x device. Black & red colored lines can be produced from either a bad monitor or a bad video card. Your K8S-MX motherboard can not run DDR1 ( unless you mean that slot 1 DIMM you replaced). Your board only supports, 2x184-pin DDR DIMM sockets for up to 2GB non-ECC PC3200 / PC2700 /PC1600 DDR DIMM's. No video display suggests your video card may be going bad or monitor is going bad. To prove this concept, please temporally switch your monitor with a monitor you know functions correctly. If you can not temporally switch your monitor with someone else than replace your AGP8x video card. You can find up to six pages of AGP8x video cards listed at the link below.

The XFX cards carry Lifetime Warranty.
If you find you have more questions feel free to ask.

Good Luck & Kind Regards.

No Video Output - HP 6635 Desktop minitower - CPU Intel CELEROM 533Mhz


if you have changed the monitor and the same no signal have you noticed a beep sound? or can you see the green and red light in front of cpu? if both of this doesn't light it's power supply and if there are led lights (green&red) lighting but there is a continous beep sound the problem is the on board video card. if a sound short beep, beep the problem is your memory card.
