Webcam doesn't work on Aspire 5670

Hi,

Just got the Aspire 5672WLMi last weekend. It is my first ever laptop and it seems decent enough though i haven't really tried to put it through its paces yet (runs UT2004 fine with all settings on max though). It's a shame i am buying it here in Beijing though, by default it only comes with 512mb of RAM! Now has an ok 1GB.

Anyway i can't get the webcam to work. Because i wanted an English version of windows the people i bought it off d/l all the drivers and stuff in the shop, though i didn't really pay much attention. I now regret this as i don't really know what they used and i want to do another reinstall.
Sorry off the point again. I did download the built in web cam drivers and did a clean reinstall of them. The computer sees it and the LED comes on when i select it but all i get is a grey square where my ugly mug should be. To my mind it is broken but i have no experience with webcams so could be wrong.

Is this a software problem i can fix or do i need to take it back?

um, as it is China maybe i can say forget the camera and in recompense give me more RAM/better graphics card...worth trying huh.

As an aside, will it be possible to upgrade the graphics card some time in the future with this model?

Cheers for any help!

I know i may not have seemed that bothered but it is annoying so if anyone does have any ideas with the camera that would be cool.

I was also promised that my Graphics card was the one with 256mb of onboard video memory but i am really finding it difficult to find out if that is the case. Most things which see the card just see the 512MB. i.e. it includes the system memory that the card also uses. However Sisoft Sandra states:
Total Memory: 512mb(128MB Video) (246mb System)
Texture Memory: 378MB

Perhaps I am being dumb but the sums don't work out for me. 128+246 = 374 which is still 138mb short of the 512mb it initially states. Is it infact texture memory + the 128mb onboard that equals the 512mb? So assuming the 378mb is system memory then my card is just the 128mb variety right? I just don't quite understand where the 246mb comes from.

Does anyone know of any quality detailed software which should be able to make all the distinctions? dxdiag and the empowering software don't do the job.

Thanks again,

um, just checked what 3dmark06 sees, it says:
Total Local Video Memory 134 MB
Total Local Texture Memory 134 MB
AGP Aperture Size 248 MB
i guess the 2 locals is the onboard memory right? which would indicate i have the 256mb card...sorry, could someone who knows how these things work please clarify all this for me...
