My story in summary goes like this

-installing usb devices and software
-computer stuck in reboot loop
-i triede safe mode, boot to working configurations etc.....everything and still the loop remained.
-so i did an xp repair

halfway trhough it was installing drivers. It asked for an install file for my intel graphics card.
I thought i could do that later so pressed cancel and carried on.

However the repair hasn't worked.

I now get the BSOD with the errrors: 0x0000007f (0x00000008, 0x80042000, all zeros...)
But yay no looping restarts.

I then turned my PC off and came here.

I hope someone can help.
thanks

Hi. Have you tried repeating the repair install, this time with the graphics driver it looked for last time available to install when needed? This guide may be helpful: http://www.geekstogo...ws-XP-t138.html

[makihara]

it wasn't helpful unfortunately.

The key thing i forgot to mention was that these erros are the same ones i got originally with the looping restart. They came up in boxes like " your system has just recoverd from a serious error". When i clicked more info i got the same errror message si get now with the BSOD.

What i'm looking for is some help in using safe mode to get my computer back to when it was completely fine.

System resore didn't seem to work last time.

So now i'm thinking my registry maybe the problem. Is there any way to check?

thanks

From your description and those error codes I suspect you may have some bad memory (or motherboard). Try this free utility: http://www.memtest86.com

Installation
===============
Memtest86 is a stand alone program that cannot be executed under windows and must
be loaded from a floppy disk.

To install Memtest86:
- Extract the files from the zip archive
- Open the directory where the files were extracted and click on "install.bat".
- The install program will prompt you for the floppy drive and also prompt you to
insert a blank floppy.
- To run Memtest86 leave the floppy in the drive and reboot.

NOTE: After the boot floppy has been created you will not be able to read the floppy
from windows. This is normal.

Do you have norton antivirus installed (or another AV program)?

Uninstall in safe mode -- see if the problem persists

[makihara]

memtest - i unfortunately cannot get acces to another computer with a floppy drive or cd burning capabilities until monday.

norton antivirus - when i go into safe mode i get the same BSOD

by the way what is "dumping physical memory" it has some sort of ticker counting something. Normall i just turned the PC off but should i wait?
edit - It got to a 100 then said some error then restarted.

anyway is it time to try a complete reinstall of windows or should i reformat the hard drive. no idea if there the same or how to do them!

thanks

Gerry suggested you uninstall Norton AV in safe mode.

Ignore it. Standard procedure.

No. If you do have a hardware problem, formatting and reinstalling will not help.

1. Uninstall Norton in safe mode.
a. If the problem goes away, let us know and we'll go from there.
b. If there's no change, reinstall it.

2. Run memtest to eliminate hardware issues.

sorry i think you misunderstood, but it could be me...

i would uninstall norton AV in safe mode but i can't get into safe mode to uninstall norton antivirus. Every time i go into safe mode i get the blue screen error messages.

No. If you do have a hardware problem, formatting and reinstalling will not help.

when you say hardware we're talking ram, motherboard and stuff like that...correct?

So as for your list of things to do:

1. Norton AV - i can't even boot to safe mode let alone uninstall anything once i'm there.

2. Memtest - i will do this as soon as possible. I'm working on getting the floppy.

thanks for all your help by the way

ok i managed to get the floppy with memtest on and booted it up.

it went through the nine tests smoothly.

In the table there was a lot of information but the main info was: one pass was completed and there was a 0 under errors.

i presume that means there were no errors recognisd by memtest.

can i rule out hardware issues now?

i'm still getting the BSOD obviously.
i was looking at the microsoft support pages - http://support.micro...kb/137539/en-us
it seems to say i have a double faulttrap. Can anyone help me understand this.

Quote

A double fault occurs when an exception occurs while trying to call the handler for a prior exception. Normally, the two exceptions can be handled serially, however there are several exceptions that cannot be handled serially and in this situation the processor signals a double fault. The two primary causes for this are hardware and kernel stack overflows. Hardware problems are usually related to CPU, RAM, or bus. Kernel stack overflows are almost always caused by faulty kernel-mode drivers.

under solutions it says

Quote

Test the RAM in the computer by running the diagnostic software that is provided by the computer manufacturer. Replace any RAM that is reported as bad. Also, make sure that all the RAM in the computer is the same speed.

didn't i do this with memtest?
what would i be looking for, for the "diagnostic software provided by my manufacturer"?

thanks again and a happy new year

Let's back up just a step...you cannot boot into safe mode, or real mode?

(just making sure).

You basically have a completley non-working machine?

You do however have a windows cd?

[makihara]

before the memtest

i get to the windows xp welcome screen and then the BSOD appears
this occurs in normal mode and safe mode

after the memtes

in normal mode i now get to the desktop. 20 seocnds later....BSOD
i havn't actually tried safe mode again.
I presume it would be the same
i also havn't tried botting to last known working conditions.

(i'm not suggesting that the memtest had anything to do with the change it's just that's the order things happened)

i do have a windows cd yes.

thanks

You could still have a CPU or motherboard issue, but that would be rare since you passsed memtest.

Since you have a Windows CD, my next step would be a repair installation of Windows XP:

Try it and let us know how it goes.

i already tried that. As the title says the winbdows repair failed. Should i just try again?

if my hardware is ok
yet a repair installation does not work

what must be the problem?

any ideas anyone?

thanks very much

[admin]

What happened whan you tried the repair? How did it fail?

[makihara]

Before windows xp repair

-every time i turned pc on i got to the desktop
-an error box would popup "your system has just recovered from a serious error"
-i click more info - i get the error codes i wrote down several posts ago
-the computer then automatically restarts

During windows xp repair

halfway trhough it was installing drivers. It asked for an install file for my intel graphics card.
I thought i could do that later so pressed cancel and carried on.

After windows xp repair

I get the BSOD with the same error messages i got inthe popup box originally.

thanks
