my computer screen flickers or skips when i scroll up or down

[jaxstarke]

it was fine a few day's ago but then it started doing this. i've already went into the monitor settings and some people say to change the refresh rate but i don't have a refresh rate option. all i have is default monitor. i need a step by step instruction on how to fix this. it's driving me crazy!!!

Let's start with this - Download and install the latest driver for your video card. Also, if there is a driver for your display, install that.

You said this just started - what happened just before that - new hw, sw, virus, error, etc?

[jaxstarke]

how do i figure out what video card i have? i installed a game right before that and uninstalled it because i didn't have the right video card so i just said the heck with it.

[jaxstarke]

it's also seemed to slow my comp down a bit. i used to be able to click and go but now it takes it a while to do anything. i think maybe when i uninstalled farcry2 i might have uninstalled something else.

Look in Device Manager

how do i figure out what video card i have?

Look in Device Manager.

[jaxstarke]

i checked out the device manager under video controller and it says video controller (VGA compatible). in the box below it says the drivers for this device are not installed code 28 and that if have the cd rom that came with device to insert it now. i don't have and have never had the cd rom. it also says unknown manufacturer. what to do now? please be patient because i can be an idiot at times.

Is there a listing in device manager for Display Adapter? If so, that's it.

Do this... GO to Start, and then RUN, then type dxdiag, then save as and save the file on the Desktop and then attach it here and will tell you what you have.

[jaxstarke]

no there is no display adapter choice.

[jaxstarke]

you'll have to walk me through the save and attach process. sorry

[Allan]

Okay. Download and run either aida or belarc advisor and either of those will tell you about all of your hardware.

[jaxstarke]

i could write down what it says and then put it on here but i need to know which tab i should look under.

[jaxstarke]

ok i did the belarc thing. now what?

[Allan]

What does it show for your video adapter?

[jaxstarke]

i see nothing about video adapters under any of the headings. the headings are operating system,processor, drives, system model, main circuit board, memory modules, local drive volumes, network drives, users, printers, controllers, display, BUS adapters, multimedia, virus prot., communications, other devices. there is nothing under any of these that lists video adapter. my display header listed (none) under it. does that help?
