putting the monitor on another system? I have seen many monitors do similar things, and usually it is the monitor.

what did you do to realize the video card is not the problem?

if you tried two known good monitors, then maybe one of the contacts in the 15-pin video port on the computer is bad. unfortunately, this is too costly to fix rather than get a new monitor.

i did try 2 good monitors and i also bought a new video card it seem both are not the problem, according to my friend it just turned off one day

well im going to try to get another working monitor and try it out with a video card if it doesnt work i really dont know hwta to do

you are downloading the drivers right for the monitors, correct? are you checking device manager to see if the display adapter has been disabled for some reason? and you are putting the video card in the right expansion slot, pci? i know some of these may sounds like stupid questions, but...

something could've happened where your display adapter was disabled, or there's an irq conflict between your monitor and something else. or you're putting the card in a bad slot. i've seen that before.

the monitor recieves no signal what so ever you can here and see all the leds on the computer light up, but the monitor will say no signal

when does the monitor go to no signal? Right away, or after is starts loading Windows?
If it is right away, or does not go on at all, it may be a setting in the BIOS, reset the BIOS with the jumpers or switch combo.
If it is in Windows, try safe mode, then drop the resolution and Hz settings.

Does the MB have built in video? If so, try switching the monitor to that port.

Also, what slot is being used for the video card? AGP, PCI, PCI-e?

thats right i forgot about bios i might give that a try if all else fails, now i gotta find the jumpers

Do you hear the "bep" from speaker? If not, check the RAM module or reset the bios. If you hear the "bep" then the problem is your Hz videocard becouse the monitor is shuting down.
In this case you must enter safe mode and unistall the video card from "Device manager".

In my experience, i encounter some broken mother bords with this behavior (All runing, but no "bep" at start and "No Signal" msg on monitor. Try to change your MB.

Hi,

The NO SIGNAL on the monitor means that there is no video reaching the monitor, so something is amiss in the box. You won't be able to do anything with the bios because you can't see what you are doing.

Try these ideas.

Replace the video cable to the monitor.
Try a PCI video card, or if its already one put it into a different slot.
As mentioned in another post, check whether the mobo has onboard video, whether it is disabled (some mobos sense plug in video card and automatically switch off the on board video).
Try the on board video (if there).
Try safe mode.

Everyone, i am having the same problems. I guess the best way is to contact the support on the webiste, mine is visiontek and im emailing with them.

I still havent fixed it, but sometimes there is something there its not compatible with.

Your game it's changing rezolution and refresh rate. Try from you video card software to overide game resolution.

Also no signal to the keyboard. Sometimes I get the beep sometimes I don't. I'll try putting in a video card, video is built in. Did you get it fixed?
