How to change my display adapter to a standard VGA mode?

How do I fix my computer monitor display problem?

• Warning- the following is rather tedious going- I recommend reading on only if you do not get bored easily... Can anyone suggest what is wrong with my display set-up? Does fault lie with the monitor, graphics card, motherboard or general settings? I can no longer properly work with my offline machine which I use primarily for rendering graphics and animations. I left the machine on overnight last week and found the monitor off but flashing brightly roughly once a second. I tried the monitor on another computer and found the same problem. I decided to get another monitor that day (Hyundai w240d) and also a cheap graphics card, to be on the safe side (Nvidea Geforce 520). It's installed in the PCI-Express slot of a GA-73PVM-S2H mo-bo. In high resolution mode (native) the picture starts fine and displays as it should (shortly after start-up), then the display rapidly deteriorates; starting with a few sparkly points of light in roughly certain regions, then the image becomes unsteady (a sort of bounciness towards the bottom of the screen) then completely decends into rubbish- going berzerk and and not really showing anything useable. Putting the display into 720 (instead of 1080p) seems to more or less fix the steadiness problem (though not completely)- but ofcourse then I have to contend with overly-large icons etc. Even then, certain types of image display more steadily than others. Images with lots of stripes in them- such as a wood-grain texture etc. display less steadily than say a matte white surface. I think this might be quite telling for those of you in the know as to where the fault should most likely be (monitor or tower). I have tried disabling the onboard graphics (incase of conflict)- I have tried altering the settings on the monitor & all the different kinds of hook-ups (DVI, VGA-DVI, VGA - VGA & HDMI; only HDMI & VGA-VGA will work...). Importantly the Nvidea driver doesn't appear to have fully completed it's install- which I am quite sure is related- and after it makes makes the re-start request and I go ahead with that, the only change which appears to have been made is windows (XP) finding a new device and requesting 'Windows UAA audio driver update' (or something like that)- which does not get carried out- despite offering online search, or the motherboard driver disk/ graphics card disk/ monitor disk. So that fails and the I get the message that the device has not been installed and may not work correctly. But that's a seemily unrelated piece of kit- I would have thought...? Anyway- I think that's all the relevant stuff I can think of to mention about this. Thanks for reading- any ideas are appreciated.

• Answer:

  does the new VGA card have HDMI? If yes then this is the UAA device it cant load, and the issue you are getting is probably related to the driver install not completing. I would suggest your best option is remove the VGA device from Device Manager, this should load the default drivers. Then remove the drivers and software from Add and Remove drivers and reboot when done. Download the latest drivers from the NVidia website and install those rather than the ones on the CD and hopefully it will resolve the issue. If you are still getting the same issues then I would suggest you look to the RAM modules for the fault.
