What is causing my fuzzy/vibrating computer screen?

What is causing my fuzzy/vibrating computer screen? it is not the Monitor?

  • I have an old e-machines t6412 desktop, and i woke up one day to a fuzzy wiggly line computer screen image. It is not the monitor, because i have tried a couple different ones. I also have tried messing with the monitor resolution settings but it didnt really help at all. Could the graphics card cause this or video card? are they the same thing? im not a big computer guy, so idk the difference really. Doese anyone know if and what kind of graphics card i can buy and put in it to see if that fixes it, and how would i go about doing that with the old one still installed? any input or help is appreciated.

  • Answer:

    The graphics card is where you plugin your monitor. Some systems come with two graphics cards, one that is integrated with the motherboard and another that goes into one of the slots on the motherboard. If you have two, you can alternatively connect your monitor to the two cards to see if any one of them work. If you have no luck with that try changing the RAM. Here too if you have multiple sticks of RAM you can try to remove one stick at a time and test to isolate the faulty RAM. If its not the graphics card and its not the RAM then we are only left with what could be a faulty motherboard.

Check onboard display by removing the graphic card and connect the moniter cable to the onboard vga port. If it happens again it is the ram problem.
