I've just recieved a PM asking me about chipsets, so I thought i'd answer it here for anybody else who might be wondering.
Chipsets are traditionaly made up of two seperate microchips, the North Bridge and the South Bridge, named after their original locations on the motherboards that first used them (one at the top, one at the bottom).
The North bridge is responsible for transporting information from the memory to the CPU via the Front Side Bus and vice-versa. Typically, the CPU works much, much faster than the memory and so a 'manager' is needed to make sure that the correct information is sent to the CPU at the right time, and that the processed information is delivered back to the memory as quickly as possible.
Some North Bridges are also responsible for 'off-loading' other jobs onto additional hardware. For example, if the processed information leaving the CPU is meant to go to the graphics card, the north bridge will handle this without any interaction from the CPU itself. Nowadays, however, a part of the CPU itself is usually responsible for doing this rather than the North Bridge.
The South Bridge Can be thought of as the computer's 'eyes and ears'. It contains all of the electronics needed for handling all input / output operations such as reading from the mouse and keyboard and sending and recieving information to and from the USB ports.
On motherboards that have on-board graphics, sound and network ports, the south bridge is also responsible for these functions as well, although there are often some additional microchips that are controlled by the South Bridge to help improve performance by taking some of the strain off the South Bridge itself.
However, the South Bridge needs the CPU to do some of the calculations for it in order to drive the graphics and sound of a computer. This is one of the reasons why adding a graphics card and / or sound card can greatly improve a computer's performance, since the additional card does all of the work without having to use the CPU as much (and consequently the main memory). Adding graphics and sound cards does not render your chipset useless because it still has to do the very important jobs mentioned above.
There a number of chipset manufacturers, most notably VIA, SIS, Intel and Nvidia. Whilst all chipsets do the same thing, some techies prefer a certain chipset vender over others, mainly due to performance issues or just plain personal reasons!
One last note, the Nforce 4 chipset actually consists of only one chip rather than two. The North Bridge and South Bridge are combined on one big microchip rather than two seperate ones, but it's still a chipset just like all the others!

@Gigs
I had my fingers crossed behind my back 
@Dude
Everything should work fine providing that you're running Windows 98 Second Edition, not first (or a newer OS, of course).

what isp have you got? maybe they are cutting you off after a certain period of time. oh does it happen with any big download or just on certain pages? this problem cant be browser related as far as i know, so must be pc or isp related

i had similar problem, and it was due to bad isp- to download with mozzila you must have uninterrupted data flow (speed may vary, but flow must be continuous). use flash get 1.6, it can resume broken download.

@temp
Yeah, i agree with the others here, definately sounds like you've got a dodgy connection. This is usualy due to either your ISP or phone / cable line or (more commonly) viruses and / or spyware on your PC.
Give your PC a thorough clean up to make sure that it can't be malware related and if the problem persists, phone your ISP.

Here is another question for you, hope you dont mind. We are going to get another PC in the house and want to conect it to the interent with wifi, now the main PC already has a router so there is wifi in the house all i need 2 know is what does the new PC need to have 2 be able to conect to it. I know with a laptop all u need is a wirless PC card but not all desktops come with a PC card slot so im not sure what i need.
Also if a virus is downloaded onto the new PC is there any way for it to transfer to the main PC?
Oh and 1 more thing, as we have 8mb at home is there any way to limit the new PC to lets say to 2mb?
Thanks a lot |

@p900
1. Your desktop PC needs only a PCI wireless card. It slots into any spare PCI slot actually inside your computer (you have to take the side off to fit it!). The PCI slots are the ones where your dial-up modem (if you have one) are fitted.
2. Yes, viruses can spread over networks. All PCs on the network should have their own antivirus program running.
3. Some routers allow you to impose cap limits for each client on the network via the router's control panel.
