Juddery screen

I have just finished installing windows on a new PC and I have installed sound, motherboard and graphics card drivers - all latest that I downloaded today. But when I move something around on screen, say a window, or scroll up and down it has a bad juddery effect. I have this all the time before installing graphics drivers but never after. I've already re-installed them. What could be causing this?

in dxdiag it doesn't show any information about the GeForce 7300GT thats in there. Could it be the really old CRT monitor thats plugged in? There is no integrated graphics on the motherboard so the 7300 is the only place to plug them in.
 
Whats happened to this forum? People used to help you within a few minutes of posting. Can nobody help me get windows to recognize my 7300GT?
 
go to device manager and check display adapters, does it pick up your card in their? as a 7300gt? or does it have a yellow exclamation mark next to it? Install all the latest Drivers for your card and also re-install directX.

what is your monitors refresh rate? have you also tried a new monitor?
 
It shows the 7300GT there and a yellow exclamation mark. I have reinstalled several times now. Trying in safe mode now. Also I am trying different monitor.
 
After I uninstall drivers and restart it says it has found new hardware but it says, 'Video Controller (VGA Compatible)' instead of nVidia GeForce 7300GT. Thats a problem.
 
Yes it won't show the name of it, when drivers are uninstalled, because windows doesn't recognise what it is. when you install the drivers windows then recognises the device and knows how to use it. I would download the very latest drivers off the nvidia website(nvidia 7 series). that should fix it.
 
I've installed them and uninstalled them installed in safe mode etc.... nothing works. Even installed DirectX 9.0c but it still wont accept the drivers. The PC can see the graphics card but it won't accociate the drivers with it.
 
are you getting the correct Graphics card drivers for your OS? e.g. Windows XP 64 bit. If you have and as you said you've re-installed the latest drivers many times with no luck also re-installed Direct X then it must be a hardware problem. It will either be graphics card or motherboard. could be the Graphics controller located on the northbridge chipset has malfunctioned. What you should first try is another graphics card if you've got one laying around, if it has the same problem it's gotta be motherboard.
 
Also consider trying an older version of the nVidia drivers. I'm not sure if it'll make any difference, but it's certainly worth a try.
 
I've only just installed directx so i dont think thats the problem. I don't have another graphics card except my 9800GTX which is huge and wont fit the AGP slot anyway.
 
DirectX wouldn't make any difference. It's a lack of working drivers that I'm guessing is causing the problem... or a faulty card :)
 
install the standard VGA drivers you mentioned earlier, reboot & then install the latest drivers and all should be ok, failing that, install standard VGA drivers and shutdown then remove & reinsert gfx card, boot & it should be detected & install latest drivers

BTW: that worked on old Win9x anyway
 
Make sure that you also have the drivers for the chipset installed before you install the video drivers. If the buss isn't recognized correctly, Windows can't do much with the video drivers.
 
I can't find any chipset drivers for the motherboard. PC Chips M811 v3.1. On the PC Chips website there are only USB2.0, LAN, and onboard sound drivers.
 
[ot]How in the world does PCChips stay in business? *shudder*[/ot]
It looks like PCChips doesn't actually bother to host the drivers for you, but that is an older VIA chipset. You can get the latest VIA 4-in-1 driver pack here:

VIA Arena - Display Drivers

...After installation, you will probably need to reinstall the video drivers and maybe a few other things as well.
 
Thank you very much. I have different problem that stops this now. I don't have installshield. Where can I get it?
 
EDIT: IF YOU READ WHAT I JUST POSTED, SAFE MODE FIXED IT. IF YOU DIDNT THEN FORGET IT.

By the way, should I get the 'Retro chipset VIA 4in1 drivers' pack or 'VIA Hyperion Pro Driver Package' pack. I can install them but I don't know which one to get.

EDIT2: I installed the 4in1 pack but it didnt change anything. I reinstalled the graphics drivers after also. I can't find button to uninstall the 4in1 pack so that i can try the other pack.
 
I have installed a 4in1 pack of drivers for the VIA motherboard, which included AGP drivers, and I re-installed the graphics card drivers after but still the screen judders badly. Can anyone suggest anything else it could be other than hardware fault?
