Hello,

I have had several BSOD's on my Zepto 6615WD since I bought it.
So I have done a clean install (again) of Windows XP SP2. I have installed
the drivers
Zepto has provided and I have installed the drivers in the
order that they have recommended. The drivers have been
installed in this order:

Audio: Realtek HD Audio 1.64
BisonCam: 2.6.0.20
Cardreader: 2.0.0.4
Infrared: 5.1.3600.7
Modem: 6.10.3.0
Touchpad: 8.3.4.0
Chipset: Intel 8.1.1.1010
LAN: Realtek 664
VGA: Nvidia 9.7.4.4
WLAN Intel 54Mbit: Intel 10.5.1.72
WLAN Wpro 300Mbit: Atheros 6.0.3.62

I have uploaded a zip file which you can download from:

http://www.cherubia.com/debug.zip

The file contains screenshots, dmp-files, debug information and the
technical specs for my laptop.

I don't know exactly how to reach any conclusion from
the analysis of the dump files in windbg. So I hope there is a kind
soul (and expert) in this group who would be so nice to take a look
at it and help me figure out what's wrong.

I should also mention that Zepto delivered the laptop with BIOS
version 1.10, but I learned that they pulled the BIOS version off
their website after they found out that the v.1.10 BIOS made
laptops unstable. So - based on their advice - I downgraded my
bios to v.1.09 _before_ doing a clean install of Windows XP SP2.

Here is a list which describes the typical problems I have with
this laptop:

1) I am downloading a file and listening to radio over the internet. I leave
the laptop and return after a few minutes. The
netradio is still playing but the screen has gone black (like a
pausescreen). I can't return to the desktop by pushing a
button on the keyboard or touching the touchpad. I have to turn off the
laptop by pressing the off-button for some seconds
and then restart the laptop.

2) The on/off-switch for the wireless network adapter does not work. When I
switch to "off", I still have wireless access
to the internet.

3) Right after starting the laptop and logging in I get a BSOD and I have to
restart

4) Right after starting the laptop and logging in, I leave my laptop and
return a few minutes later. I see a BSOD and I have
to restart. In other words, I sometimes get BSOD without even using the
laptop.

5) I open a browser and surf a little bit. After a few clicks here and there
I lose wireless access. The list which usually shows
available wireless networks is empty and refreshing the list doesn't help.
Doing a "repair" does not help either. I have to restart
the laptop to re-establish the wireless connection. At the same time, I can
surf wirelessly with no problems on my other laptop.
I have run a netstat in DOS and it reports back very slowly until I close
skype. Sometimes, doing that, will re-establish the
internet connection. From the netstat, I can see that some application is
trying to access a lot of different ports (probably skype
trying to communicate?). However, the same version of skype runs smoothly on
my other laptop.

6) Before I leave the laptop I close the screen down so the laptop goes into
standby-mode. When I return I pull up the laptop
screen and I see that the ON/OFF-button is still lit up. The screen,
however, is black. I press the ON/OFF-button and either
[1] the laptop shuts completely down or [2] the laptop doesn't react at all.
In the latter case, I have to keep pressing the button
down until the laptop shuts down.

7) I pull the screen down so my laptop enters standby-mode. When I return
from standby-mode I get a BSOD.

I have checked the laptop for vira and spyware, but nothing was detected.

I have run memtest (for a whole night) and a tool for testing the hard
drive, but memory and harddisk seems to be fine.

I have also run some stress tests (BurnInTest from passmark) but also there
I get no errors.

Please help ) Thank you...

Forgive me my shortness here - but why do you put up with this?
If it's still under warranty I would be quick to return it.

Which wireless is installed in this "Zepto" thing -
Centrino or Atheros?

Atheros

Because if it turns out that the BSODs are driver related then the
warranty doesn't cover that and I will have to pay a lot of money
for "nothing".

That's why I have been trying to diagnose the problem using
windbg. But I am not an expert in this area, so I am seeking
somebody who can help me determine the cause(s) of
the BSODs.

Seek and you shall find )

As a regular user you should have no idea what a driver is or if some
'driver' is the cause of the system crash. What you know is that you
bought a laptop from some company and it doesn't work. It is not your
responsibility to determine why it doesn't work. Return the thing and
buy another laptop from somebody else that does work.

Some driver is corrupting memory. As your dumps are not consistent,
the perpetrator is not likely to be be any of the blamed components
from analyze -v. Send the POS back and buy something else.
