want a faster windows XP

Hi everybody,
Please help me. I would like to know this...

1. I'm using winXP and Norton Systemworks. For winXP, they have their own
disk defragmentar and their error-checking. But norton also have Speed disk
and Norton disk doctor in norton utilities.

Is XP's disk defragmentar has the same function as Norton's Speed disk?
If yes, which is better and which should i use ?
If no, what is the difference between both and which should i use ?

IS XP's error-checking has the same function as Norton disk doctor ?
If yes, which is better and which should i use ?
If no, what is the difference between both and which should i use ?

Or can you suggest any other option for disk checking and defregmenter.

Pls help me about this, i'm using norton's Speed disk and Norton disk doctor,
but some person say this is good and some say this bad...i'm confused and
don't know which to choose. That's why i'm writting here.

2. In my 3dMark01 and 3dMark03, it show's like this:-
Total Local Video Memory : 128Mb
Total Local Texture Memory : 128Mb
Total AGP Memory : 120Mb

Why is my total AGP Memory is only 120Mb. Isn't it supposed to be 128Mb ?

3. I found that i can speed up my boot up process by installing "Bootvis"
from Microsoft. But this is only for WinXP.
This is the website:

Can you tell me, is this some kind of useless stuff. I'm afraid it will
do something bad later because i have never heard anyone talking about
this before.
Have you used it before, or have you heard anything about it. If yes please
tell me about it.

4. Should i enable write combining in my display setting. What is it actually
for ? Will it any good or bad ?

5. For my 3dMark03 i get 4165 marks.
Where else for my 3dMark01 i got 13500 marks out of it.
Is it fine with R9700 or should i be getting better marks for my card ?

6. I'm using Norton Systemworks and Norton Internet Security. It makes my pc really slow when startup. I mean it is slow for a P4 2.66 with 1Gb of corsair ram. Can i change any setting in these norton software to make it run faster.
I'm planning to uninstall the Norton Internet Security, but i need a good firewall to protect my pc since the students in my campus loves to hack into other pc's.(is there other way i can kick their ass). Please suggest me a good firewall...
Please, i really need one....

7. If i disable the floppy boot seek, will it do anything bad? what is it for actually?
I hate the floppy noise in the boot up...

8. 1. Can i turn off "Indexing" for my hard disk in the drive's
properties. I heard it will speed up the computer a little bit.
It is "On" which means the check box is ticked as a default setting.
What will happen if it's on and if it's off? Will it make my pc fast?
What is your advise, should i off it?

9. In regedit i can edit my user name and my organization.
Select HKEY_LOCAL_MACHINE / Software / Microsoft / Windows NT /
CurrentVersion / RegisteredOwner and RegisteredOrganization. (I got it from internet).
Will it effect any other software or any other stuff if i do this?
Is it safe to do this?
I want a different name and organization to be displayed in my "System Properties".
Please tell me whether it is safe to do that since i'm planning to do it.

10. If have any tweak for winXP, please post it to me.
(tweaks which won't do any harm later)


here is my pc spec for a reference..
P4 2.66
Asus P4G8X Deluxe
2 X 512Mb Corsair XMS3200CL2
Maxtor 80Gb 8Mb Cache
Hercules 3d Prophet 9700(non pro)

I have posted this message personally to a few person and i am waiting for their answer.

I really appreaciate all your help...thank you very much...
