Rob;

Wasn't meant to be insulting. Sorry if it seemed that way to you. The
point I was trying to make is that the issues you are having have absolutely
nothing to do with your AMD64 processor. It has to do with your video card
or other driver that requires mpegport.sys. There is no known workaround
that I am aware of, although I am sure that others will post if one exists.
I wanted to make sure that other people reading this thread did not begin to
think that there is a conflict with SP2 and AMD64 processors. It's a nasty
little rumor that just seems as if it refuses to die. I wanted it clearly
understood that the "Major problem) did not exist.

Here is the best information at hand to deal with this issue:

Microsoft has released a knowledge based article that covers an issue with
SP2 and the Athlon 64. Some users are complaining of constant reboots after
they have installed SP2. The cause of this issue is the mpegport.sys file
which tries to write to the memory protected by the NX bit.



This issue occurs if all the following conditions are true:

* You install the 32-bit version of Windows XP SP2 on a computer that
has an AMD 64-bit processor.
* You configure your computer to enforce data execution prevention
(DEP). DEP is also known as no-execute protection.
* You installed hardware that requires the Mpegport.sys driver.

When you restart your computer after you install Windows XP SP2, the
Mpegport.sys driver tries to write data to a memory location that is
monitored by DEP. This behavior causes the computer to restart.
RESOLUTION
You may be able to resolve this issue if you configure a DEP exception. To
do this, follow these steps:

1. Click Start, click Run, type Sysdm.cpl, and then click OK.
2. On the Advanced tab under Performance, click Settings.
3. On the Data Execution Prevention tab, click Hardware and software DEP
enabled for all programs except.
4. Click Add, type the path of the Mpegport.sys file on your hard disk,
and then click OK two times.

The other solution is to remove SP2 entirely.



As you can see, Microsoft is aware of the issue, and it is related to other
hardware and not to the AMD64 processor.

Thanks for that post BadDog , I am having this problem that may have to do
with this mpegport.sys , can you Please WITHOUT insulting me help me work
around this?
if you have any links or help topics handy please post.

PS: I tried the "Turn off DEP for all programs and services except those I
select" option (as suggested by Carey) but after a few reboots Explorer
has
to be added then Outlook express then Steam then HL Launcher and on and on
it
goes.

I have tried:
Reinstall of XP Pro with SP2 (on disk) installed right after all the
newest
drivers in the order recomended by MS and ASUS , installing 1 program at a
time to find the problem....I've done this 3 times.

Also I have tried , installing XP Pro SP1 , getting it all up and running
(Which I mght add has NO PROBLEMS) and then updating to SP2 from win
update......still a no go.

PLEASE if you have any HELPFULL comments please advise.

Thank you ,

Rob

Sheesh!! I have never seen a more bitter angry insulting bunch of people
in
one place in my life.........No wait.......maybe the Kerry Campaign after
Bush won.

ARGGG!!! ALL I WANT IS HELP!! LOL!!!

For the benefit of those reading this thread...

There is no issue with SP2 and AMD64 processors.

I'll say that again to be sure everyone understands it..

There is no issue with sp2 and AMD64 processors.

I have it running here just fine on all my AMD64 and DEP runs perfectly.

The issue is with certain drivers that require mpegport.sys. It is
related
to a completely different issue that AMD64 chips.

Somehow, this myth keeps getting resurrected, mostly by those who have no
clue what they are talking about.

Those of you reading this thread who own AMD64 procs should not hesitate
putting SP2 on your machine. There is no problem with SP2 and AMD64.
None
at all.

Does ANYONE have any info or links for SP2 for Win XP made specifically
for
AMD 64 CPUs?

Not a 64bit version!! but rather SP2 made for AMD 64's running on a
32bit
version of XP.

There is a major problem with AMD64's and the DEP feature in SP2 , and
it
was said somewhere (I can't remember where)that MS was/would be working
on
a
special verson of SP2.

I have serched the MS site myself and come up empty , MS FAQ's/Help and
Support pointed me here.

Thanks
