Video card question

well, i have 2 computers, and i am a gw whizz, but not much of a general computer man, and on my newer laptop, my gw runs fine. on my 3 or 4 yearold windows xp pro custom built by my friend, it runs terribly, taking 2 minutes to load simple areas that should take 10 seconds. it meets all the memory requirements and such, do you think its my video card? i will make a reply to this post with the video card model once i have access to my desktop, as i am away from home right now, but any info would be great, as im considering buying a new video card for this purpose. thanks a lot

Actually the loading problem is about the computer's RAM and processor. Also it could be about the internet card.
