  • My VGA out keeps going distorted !

    Hi,

    I have some major problems with my carpc. For some reason the output of my video card keeps going distorted. At first the distortion is minimal and i can kinda keep using the pc; but, eventually it becomes too much.

    I am using a Jetway C7, 1gb ram, Matrox PCI P650 video card.

    I have checked the cpu and system temperature and they are fine. Last time CPU temp was at 45 degrees.

    Not sure what is causing this...

    Could someone please offer some assistance ?

    Thanks,

    slevytam

    PS: Here is pics of the distortion I am getting

      Tried removing the pci card and using the onboard video?
      What makes you so sure it's the video card?
      Any speakers/hdd/rom drives near the screen?

      My screen gets distorted if it's too close to the dvd-rom while it's reading on the test bench.

      P.S. No luck with those pics either
      I installed my carpc into my pet Kangaroo, mate.

        Sorry about the pics not working. I'll fix that this evening.

        I haven't tried the onboard video yet but I will as soon as i can. I know its not the lilliput because I have another 6 screens connected through the rca out on the video card and they are all doing the same thing.

        Ironically enough I just had the same problem on my work computer today and I took the video card to get tested. It was a bad chip.... I wonder if that was a sign ???

        Is there any way to monitor the temperature of a video card ?

          No luck with the pictures either. By distorted do you mean wavy lines running down it type thing? Not solid black lines, but wavy coloured lines like the entire thing has a wave going on inside it?

          If that is the case, then you have a strong signal running next to your calble, and unshielded cheap cables are notorious for this. Treat your VGA signal as a speaker cable with respect to the rules for running them next to power lines and such. Think of the distortion as the visual "noise" or "whine" that a speaker gets.

          Of course if this is not the problem, then nevermind.

                i used to think there was something loose in the monitor, and that my poly engine mounts were rattling the crap out of it, but then one day i noticed that when someone called, or texted, or if i went out and back into service the screen would go either into amazing technicolour mode (lots of psychadelic colours man) or blank.

                Put my phone in the cupholder ever since, and not a single problem since.

                    I am sorry for the late reply. Router Issues. Had to buy a new one.

                    The pics should work again!

                        Hi I saw your pics, is your v-card mounted tight. I had some what same looking picture with home computer when I would clean the back to get the dust out with a damp cloth it would move it just enough to couse distortion but never hang ofcourseI did'nt realize till re-boot where it then would'nt get any picture. Make sure pins on cord are not bent and all are of equal length just one pushed in can cause anything to BUG..
                        • If you don't get it the first time around, go get seconds..

                          Thanks for your reply... I have now i think tried everything to fix this problem.

                          First I'd like to note that using the onboard video works great... no problems

                          I have tried replacing the ram, the video card, the video cable, reinstalling all the drivers, disabling the onboard video card in windows...

                          No luck at all !

                          Can anyone offer me some suggestions please !

                          Note: sometimes when I first boot I get this white light that slowly takes over the screen just before POST... Really weird....
