Hi, I'm new as you can see and I'm having some problems with my computer.  I tried asking on the Microsoft Newsgroups site and it's slow GOING over there because things don't go to the top with new replies...hopefully I can get some help here because I'm really getting frustrated.  I'm going to copy and paste what I posted on the M$ site.

This is the first problem-

Ok so I've been having nothing but problems with my computer. (Yay
Windows!)... The other day I tried to play a video with WMP11 and about 10
seconds into the video a blue screen popped up saying something about a
hardware or software failure...I restarted like it said to and when I
restarted at the log in screen a lil' box popped up that read "The instruct
at "0x77e7ebl" referenced memory at "0x00000001" memory could not be read" I
then had the option to either terminate the program or debug it. I've chosen
both and I get the message every TIME I restart my computer and I get the
blue screen every time I try to play a video.

Videos on Youtube work BTW just nothing from the computer...emailed the
videos to myself and played them on another computer and they worked there.

What I've tried to fix the problem:

1. Uninstall WMP11-still have the problem
2. Re-installed WMP11-still have the problem
3. Tried USING RealPlayer, QuickTime, and VLC (I think that's what it
was)-still have the problem

I'm running XP Pro, SP2, and current on updates. I haven't installed
anything lately and McAfee hasn't found anything. I don't EVEN know where to
go from here so any help would be great! Also I'm not a computer expert,
just your average college student. Thanks in advance!

And the 2nd

About a month ago I upgraded my motherboard, videoboard, and RAM. I repaired
Windows rather than doing a clean install. I've since got almost everything
working well on the machine except I'm not seeing my workgroup. I can't see
the printers that are connected to another machine on the workgroup and I
also can't connect to my Xbox360 for steaming media. I can however get on
the internet with it...I am right now actually. So how do I get this
computer to see my workgroup like the rest of my computers can?

Thanks for reading...and any and all help!  Just FYI I'm not the most computer literate person (I'm not like a programmer or anything) just an average college student as far as computer knowledge.If this is XP/Vista go to Start / Run and type in sfc /scannow and hit Enter...have your XP CD handy..
As to the workgroup question since you did a repair install you will need to re-create the workgroup from scratch even though it may still appear as healthy...It is XP (SP2).  What will the "sfc/scannow" do?  With re-creating the workgroup do I need to do that on all of the machines or just the one with the problem?  Thanks so much for the reply!
