Okay, this is gonna be a very long post, so bare with me.... I have a hp Pavillion 424.uk, a fairly standard p.c when i bought it, but being an avid gamer i soon realised i needed to upgrade, since then i bought new memory and a new graphics card (Crucial RADEON x700 agp), everything worked great for months, with only a few problems with some games, but they were bugs with the game and not my p.c, i couldn't of been happier, but then my main harddrive started to go wrong, started making clicking sounds and soon enough my computer wouldn't start, i tried to get a professional to fix it, but they said it was unrepairable, so i ended up having to buy a new harddrive and a copy of Windows XP home edition. After re-installing all my drivers and software i thought everything would be back to normal, but no, my computer is having some really strange issues with my graphics card, for some reason it detects 8 "video controllers (vga comptable)", although i can install these controllers it also installs a new monitor for each (even though there is only one monitor connected) and by the 8th one the monitor goes back and makes the same clicky sound like when you try to change resolution. This forces me to reboot and instead of the standard windows xp welcome screen i get a blue screen saying windows has been shut down to prevent damage to the computer, with possibly the only relevant information on the screen being this "STOP 0x0000007F (0x00000000 0x00000000 0x00000000 0x0000000)" i think i may have got the number of zeros wrong on that, but anyway, i have to reboot and use "last know good settings" or safe mode, uninstalling the drivers is the only way i can get back into windows, although sometimes it displays all 8 video controlers as installed saying i have 8 radeon x700's but the computer is still running on onboard video. I know for a fact that there should on be two video controllers, a RADEON x700 and the RADEON x700 (secondary). On three seemingly random occaisions the computer actually gets it right and the video card works although rebooting or turning off the computer just means it'll go back to the original problem. I've tried replicating the conditions of the three times it worked, but each time the settings were different and replicating them has no effect. This problem is driving me insane, i've submitted this problem to ati and hp but they haven't got back to me at all (its been a month now). From what i can gather, there isn't a problem with my computer itself, as everything worked fine under the original windows install that came with it when i bought the computer, rather the problem lies with the new xp install, there must be some driver or some piece of software missing from the new install that hp had put on my p.c to begin with, which is now totally inaccessable due to the harddrive its on being completely useless (except as a paperweight). Anything anyone can suggest to help me with this would be greatly appreciated!

Hey nososcarey,

Welcome to PCHF.

Can you try removing your ATI graphics card in safe mode via Add/Remove programs, and then Device Manager. Then try to install it again using the installer? I've have seen this before with an Intel graphics card, and it turned out to be a hardware problem.

Also, to identify the BSOD,
- Go to Control Panel, Administrative Tools, Event Viewer and click on the System section.
- Look for event 1001, which should have the following information:

Event ID: 1001
Source: Save Dump
Description:
The computer has rebooted from a bugcheck.The bugcheck was ?
...A dump was saved in:.......?

- This will tell you where the location of the dump file is. Can you attach the dump file back here?

i would love to attach the file.... however, its 764mbs large.

uh? What is the name of the file you found from Event Viewer?

Oh, heres a copy of what the thing said:
Event Type: Information
Event Source: Save Dump
Event Category: None
Event ID: 1001
Date: 12/21/2006
Time: 1:38:49 PM
User: N/A
Computer: FRED
Description:
The computer has rebooted from a bugcheck. The bugcheck was: 0x0000007f (0x00000000, 0x00000000, 0x00000000, 0x00000000). A dump was saved in: C:\WINDOWS\MEMORY.DMP.

For more information, see Help and Support Center at Events And Errors Message Center: Basic Search.

(i can be a moron sometimes, sorry)

Soo, c:\windows\memory.dmp is 764mb not 764kb? That's not normal unless you have had over a thousand BSOD's since WinXP was installed. Are there any others? They are normally stored in c:\windows\minidump or c:\winnt\minidump?

The 0x0000007f error is generally caused by hardware. Your not overclocking at all?
