Screen Resolution Keeps Changing After Reboot

My Windows XP in terms of resolution was working perfectly but I had to reinstall it because of issues with file assignment. As usual, reinstalling leads to a plethora of problems, aside from the need to reinstall all applications. One such problem is that my screen resolution keeps reverting to 1440 X 900 after each reboot despite my setting it at 1024 by 640 pixels. I remember having the same problem way back, which I fixed somehow. Unfortunately, I can't remember what I did. Perhaps I had to download a driver but don't remember the site which I got it from. Do you have any idea how this problem can be resolved?

Here's the solution:

To keep screen resolution in Windows XP from resizing every time Windows XP is started via Parallels Virtual Machine do the following:

Start Parallels->Right click on Parallels->Virtual Machines list->Right click on Windows XP->Configure->Change 'Scale to fit screen' to "Keep ratio".

Thanks everyone for the participation.

Go to Device Manager.

Right Click My Computer
Click Properties
Select Hardware Tab
Click Device Manager
Expand Display Adapters
Right click your graphics card
Click Update Driver

Run through the steps to automatically look for the drivers from the internet.

If this fails you will need your graphics card make and model and then you need to go to the manufactures website to download the latest drivers.

just download latest drive for your video card which you can find on manufacturers web page.
If you have problem with that, just provide us a manufacturer and model of your video card (if video card is integrated on the motherboard, then provide mobo manufacturer and model)

The resolution will usually default to the native resolution of your display, and if that is "1440 X 900" you should leave it that way. Why use a worse resolution than would your hardware can display?

If you need larger text or icons you can change that without needing to reduce the resolution. For example you can change the theme by selecting one that uses larger fonts and icons, or you can also change those settings manually.

Besides, why are you still using XP? I hope you are aware of the fact that m$ support will end in April? You shouldreally upgrade to Windows 7, or if you prefer not to have to pay, then install a Linux Distribution, most of which are free.

this is definitely the display card driver problem, please install the drivers properly. you can find the display card model name on its chips top or if the system is branded install it from provided media set or download by search on Google.

I'm using the Windows XP on 17" Retina MacBook Pro via Parallels. Does anyone know how to fix the onboard video problem on that particular machine?

Should tell you which adapter is installed. Then just download from the manufactures website.

Did you try using device manager to install the driver automatically from the internet as per my previous post.

Uploading the driver automatically was the first thing I tried before even posting the question. Didn't work. The card is

Built-in Color LCD Display 2880 x 1800 NVIDIA GeForce GT 650M 1024 MB graphics

and it works just fine on the Apple side (as it did on the Windows XP side before clean-installing Windows XP). Windows XP is used via Parallels. It doesn't seem that I need to upgrade the video card driver. Something else must be the problem.

Start->Control Panel->Device Manager->Display adapters shows Parallels Video Adapter.

Updating the Parallels Video Adapter driver shows no results.
