The only error that is preventing my system to run properly is that "code 12" on the display device (as shown on the Device Manager). For some reason Vista isn't able to find enough resources for the display card, and I can't find any way to make Windows share the existing resources as XP does.

It's me again, I think what Kemical means is, you are going to have to upgrade to get the resources you need. Better graphics card, drivers etc. Kemical is a parts specialist more on that topic.

I reread your initial post and wonder about the drivers supplied by 'LG'.. Who actually makes the laptop? Unless you get a driver thats going to work then as you've already realised your going to be severly limited graphically.. Usually these drivers are supplied by the maker of the laptop so have you checked their site?

I tried both LG drivers for the graphics card and the oficial ATI catalyst drivers (which had to be installed with the help of the Mobility Modder), but none worked for me.

In the meantime I was able to figure out what is preventing Vista to allocate the needed resources for the graphics card to work: I recently installed 4GB of RAM (2x2048) which replaced the 1GB that I used to have on my laptop (2x512MB). For some reason Vista doesn't seem to be able to handle this configuration, whereas XP is able to do it.

I know that using 4GB with a 32bit operating system will always result in less RAM used than what actually exists, but if XP can handle the 4GB, why isn't Vista doing it?

BTW, my laptop chipset is the Intel 945PM Express.

Hi nfh

Could you post back what this comment you made means- "This laptop is bundled with an OEM version of XP Home and today I decided to install an MSDNAA Windows Vista Business x86 operating system."
Are you now running a dual boot system?
Is this MSDNAA Vista Business version different from other Business versions i.e.the program allows students and faculty to obtain free copies of select Microsoft products, including Windows Vista Business.?
With MSDN-AA software there are important restrictions on how the software may be used.?
I suspect this vista version has something to do with the color resolution !!!!!!!!

Ooooh good one superbill..

Hey!! I thought of RAM but I was hesitant to say because of the OEM XP and Vista 84, which is harder to adapt. (I hope you don't use Nero, I've heard it's as bad as having Norton on your machine) Can someone please tell me how RAM can be physically wrong ? They say Ram has been coming out defective lately... Well, just goes to show a person has to trust his or her own instincts.

The MSDNAA is just an MS licensing program which allows members of certain universities to get MS software for free. This is just the case: I'm trying to use a Vista Business Edition through the MSDNAA licensing program, and this Business edition is exactly the same than the one you can buy anywhere (except for the pretty package, as the software is ditributed via ISO images).

I'm not running a dual boot system. I installed Vista on a new hard drive in my laptop. I do have XP Home installed on the old hard drive and that's why I'm able to say that XP copes with the 4GB and Vista doesn't.

Hi!! How is your install holding ???? Do you still have a resolution problem ???? I'm looking at a bit of software, I think maybe it's just a series of edits. Can't tell for sure if it would hurt your machine. Lets just call it a possibility---resolution changer 3.12 freeware, shareware, software - Windows Vista Downloads (Resolution Changer 3.12)

Celestra, unless that tool fiddles with the device resources, it will not allow me to solve my problem.
In the meantime I solved my problem by replacing one of those 2GB RAM modules by a 1GB module. I'm not taking advantage of the dual channel feature of my laptop, but at least I'm able to use Vista on it.
