It should be enabled by default, but if your not certain, you can check in the nVidia display properties.
is it called write combining?

is it called write combining?
If fastwrites are not enabled by default, it's usually a good indication you forgot to install some drivers (for your motherboard/chipset/AGP).
BTW, where are you seeing fastwrites as not enabled?
well, the write combining is enabled, and i see that under the troubleshoot tab in the display properties
but, i was at the windows media player site, and i wanted to play some HD video
i clicked on the software thing they have to see if my system could play it, but they said i couldn't because i don't have AGP fast write enabled
You should be able to still play it with fastwrites off but it is usually smoother when fastwrites are on. There's a chance it'll drop frames with it off but it worked fine for me with the 6800U even with fastwrites off (although I didn't check the statistics to verify frames weren't being dropped).
Also, if you turn on fastwrites, you might have issues with games. With my 6800GT, gaming was fine with fastwrites on but with my 6800U, I had to have fastwrites off.
Edit: What motherboard do you have? That might help us help you find the fastwrites option in your bios.
i have the ABIT AW8-Max 3rd-Eye II motherboard
and when i'm watching some the HD video, it seems to have lines on it?
i think it might have something to do with the AGP fastwrite
and when i'm playing doom, it's not as if the computer is having trouble with the game but the monitor is having alittle trouble with it. it is a flat panel
could that be the reason?

Odd, that motherboard is listed as being PCI-E, not AGP.
it is PCI-E
i have a PNY 6800GT PCI-E in it
Besides checking drivers and such, be sure that fast write is enabled in the BIOS!
Usually the default presets of motherboards have FW disabled because of compatibility issues with certain cards/configurations
Fast writes is a feature introduced with AGP 2.0 that allow the CPU to adress directly the memory of the videocard as if it were part of the main ram. It's useful in games because it allow faster transfer of the vertex data (==the polygons coordinates, so to speak).
would you happen to know where in the bios that setting is located?
i've been looking all over without luck

Do you even have fast writes with PCI-e boards??????????????

Nah, i'm pretty certain Fast Writes isn't even a factor with PCI Express systems.
No, fast writes is an AGP thing. There isn't a setting like that for PCIe.
then why the heck am i getting that alert?
and on my gigabyte motherboard that's 8x agp, i can't find anything about AGP fast write

Well motherboards with PCI Express x16 does not have AGP Fast Write setting, that is only for motherboards with AGP slot. It look like to me that you took the hard drive off from your old system with Gigabyte motherboard and installed it in your new system could explain that problem you had. All you need to do is to full format the hard drive and have clean install Windows XP will solve the problem.
well originally i was talking about my new system that i just made with pci-e and then asked about my other system with the 8x agp

On my gigabyte board the setting for fastwrites is under "Advanced Chipset Features" which is hidden in the bios unless I press ctrl+F1 when I'm on the main menu. It's on by default though and Ctrl+F1 doesn't work with all bios's. Only mostly with Award bios.
thanks alot man
i apprecaite that

I am sorry to say that you are not giving enough information about your problem with no spec of your new system posted. Could you please post full spec along with:
Motherboard BIOS version
Videocard BIOS version
Forceware driver version
Could you provide us the links where you been downloaded HD videos to see if we can reproduce the problem you had and also could you take a screenshot of AGP alert you had and post it or on imageshack (http://www.imageshack.us/) for free image hosting.
When you give all the information and we will have better idea what the problem is and how to fix it. :)
i apreciate you taking the time out to help aswel
tomorrow i'll go ahead and do that on the new system
i can tell you right now it's a PNY verto 6800GT and the motherboard is a ABIT AW8-Max 3rd-Eye II Socket T
however i'll get you the other information tomorrow
