Well I have had the agp440 hang up problem many times and use to just reinstall the OS (WINXP PRO) on my Dell 8100 to fix the problem. Untill I read all the post on here and got an idea that worked for me.

WHAT HAPPENED TO ME.

I was jsut doing my usual on the web(get your mind out of the gutter) and my laptop froze. I hard shutdown the laptop and powered back up to get the lock up on the AGP440.sys.

WHAT I ASSUME...

While working my video driver conflicted with something else in windows and said #@!@
you! When I powered down that driver became corrupt. The file AGP440.sys was trying to call on the driver and being as it was corrupt could not work with it.

THE POSSIBLE SOLUTION

Before you try any of this PLEASE make sure you are comfortable working in DOS and know what you are doing.

YOU CAN MESS UP YOU SYSTEM AND POSSIBLY LOSE ALL YOUR DATA IF YOU DONT KNOW WHAT YOU ARE DOING!!!

PLEASE READ ALL OF THIS POST BEFORE YOU START.

I first booted to the "SAFE MODE WITH COMMAND PROMPT".

I then worked my way to " C:\WINDOWS\SYSTEM32\"

I then ran the program "CONTROL.EXE" This brings up a confermation window.

Click yes.

Then another window will pop up with your control panel.

I then clicked the "SYSTEM" icon.

I then clicked on the "HARDWARE" tab.

I went to the "DISPLAY" tree and right clicked and selected "UPDATE DRIVER".

Choose "INSTALL FROM A LIST OR SPECIFIC LOCATION(ADVANCED).

Then choose "DONT SEARCH. I WILL CHOOSE THE DRIVER TO INSTALL"

Click "HAVE DISK"

Navigate to your driver.

Choose the approiate driver and let windows reinstall the driver.

Finish.

Reboot.

If all went well and your fingers are crossed. You should get back to your desktop in no time.

I hope this works for you as well as it did for me.

I have the same exact problem, Bill. I tried updating the drivers and that didnt work. Thing is, I dont know where the file comes from. Its not contained in the current drivers that I see. Did everyone here update the OS or a clean install? What video card?

I upgraded from ME to XP, Ge Force. Im guessing there is a residual driver from my old ME install that is screwing this up....

Either that or it could be an IRQ conflict. Im going to try moving some hardware around and see what that does.

My Dell Insiron 5000e has the problem in Win2K, and it occurred after switching to 1400x1050 on another monitor, then shutting down without switching back. (maybe coincidence?)

It's a dual boot machine with XP Pro, and XP starts fine. At least I could get my data off.

Booting in safe mode worked the first time, then screen went crazy and couldn't be rebooted that way either.

I just came from Safe Mode!

I read in another forum that a guy deleted every agp440 key in his registry and it worked for him. I was going to do that in my next attemtp if updating the drivers didn't work...

I hope that it works for you too...

I had the same problem as described in the original post. I thought that there was an issues with agp440.sys since that was the last file name I saw when booting into safemode before the box froze.

It turns out I had a motherboard problem, as I stripped all the cards from the box and planted a different harddrive with a clean win2K install into the machine and the same thing happened. I took that same harddrive and planted it into another box and it booted fine.

To top it all off, I booted into safemode with the clean/functioning harddrive and agp440.sys is still the last file that shows on the screen in a healthy install, so seeing that file name before the freeze may not mean that agp440.sys is the actual problem.

I am getting the same trouble as you all,
with system stopping at agp440.sys in safe
mode [win2k].

In my particular case, the machine has been
working fine (BP6 w/2X 500MHz celeron, 768MBs
ram) for at least a year. I use this machine
mostly for multi-track audio recording.

Went for a location recording with the
computer today, for the first time in years:
of course, that's when the computer decided
to crash. Which probably means that somehow,
as someone else mentioned, it is tied somehow
to hardware trouble.

I still can't get the machine to boot, and
dread re-installing win2k. If anyone comes up
with a brilliant solution, I'd be very much
in their debt.

Thanks!

Similar problem to Martin Dupras.

I had a BP6 w/2X 500MHz celeron, 384MBs of RAM, a Riva TNT video card running Windows XP (latest updates as of late Feb 2001).

Problem started when I couldn't boot the computer into windows claiming that the ntoskrnl.exe was corrupt or missing.

Nothing had changed hardware or software in about 2 weeks.

I tried booting from the floppy (several types win95, winXP, maxtor util) and the CD (winXP) to no avail. Tried today replacing the motherboard with a MBI D6VAA motherboard with the VIA 694X chipset (what I could find fast at CompUSA). I only placed one of the celerons in the board and have only installed the video card, harddrive and cdrom.

Now I am able to boot onto a win95 floppy however if I try and boot from the winXP CD into Command-line mode it hangs up when loading the agp440.sys file. Same problem when I try and boot to command-line from the HD. Cannot boot normal to HD or CD.

I tried adjusting the AGP aperature from 64mb to 16mb and tried turning off caching of video memory.

Any ideas as to what is going on?

Thanks!

Re: The agp440.sys problem.

Installed XP Clean, without downloading the "updated" system files from MS. (Installed absolutely nothing else, just to prevent problems.) Couldn't get my video card (Hercules 3d Prophet Kyro II 64 MB.) to work at all, no matter how many new drivers I tried. It just didn't want to hear it.

Uninstalled, reformatted, reinstalled XP. I wasn't getting any "incompatibility" messages between XP and the hercules drivers, so I thought I was all set. Then this agp440.sys crap starts up. Couldn't boot, not even in safe mode.

Booted from a floppy, and renamed agp440.sys to agp440.old. Restarted fine, outside of an error message I get on boot. (But at least I get into the damned system now!). Video is absolute crap, though.

The hercules drivers are loaded, but I get a "This device cannot start (Code 10)" error message, because of the problems with agp440.sys, so I don't even know if my hercules drivers would even work yet!

Anyone out there find a definitive solution to this crap yet? I've flashed my bios, tweaked just about every bios setting available, set them back to default, reinstalled motherboard/chipset/video card/whatever else I could think of drivers until my eyes bled, disabled and reenabled the device. Nothing.

Intel doesn't have a solution I could find, neither does Microsoft or the Hercules website. However, if the X amount of forums I've seen regarding the problem are any indication, this is a major problem that's been around for a while, with no fix in sight.

On a clean install, if I use the setup disk files without updating them, I get no agp440 error, but I can't install my video drivers. If I update the setup files, I don't get an incompatibility message, but agp440.sys doesn't work, which makes me think it's a problem with the updated setup files. Then again, it's only a theory.

Booting in Safe Mode it hangs loading AGP440.SYS. I reinstalled WinXP from recovery CD 3 or 4 times but I had the same result.

Booting with DOS (Win98 Boot Disk), I deleted that file (c:\windows\system32\driv ers\agp440.sys). After that, the computer boot OK but without AGP suport. Now I'm using my laptop for work, browse internet but I can't use the ATI 3D features on video card. It works in VGA mode (1024x768 32bits). I can't install any driver without agp mode enabled.

tryed to open windows explorer to search for a file. Got a message that windows explorer had experienced are error and HAD to close, sorry for any inconvience (what a joke!). this happened about 4 or 5 times trying to start windows explorer, so I thought I'd reboot (mistake number x ?) hasn't boot since.

safe mode, the last file referenced is the agp440.sys driver.

did notice the referenced agp440.sys driver was shown in the safe mode boot as being in a directory \DRIVERS\ but the actual directory is \drivers\, doubt that makes any difference but thought I'd mention it.

guess i'll try the rename trick after work. I really need to save me mail if I can..

The laptop seemed fine when I got it but then it started locking up when I begain to use the mobility radeon to do hardware 3d.
Now its rate of locking up has increased horribly fast and I cant use it for more than 10 minutes at a time without it locking
and making a horrible black-screen with an odd pattern.

I am using XP and cannot boot safemode because of the agp440.sys file locking.

I'll just go ahead and add my problem, too, although it's not half as bad as most of these posts. Ever since I installed 2k server on my clone with a BXmaster motherboard, Intel P3 500, & nVidia Geforce2, it's stalled on boot-up. I turned on boot logging, I booted in that step-confirmation-safe-mode and saw it stall while loading agp440.sys. After reading all these posts, I'm not half as bitter about my 'puter taking 5-10 minutes to boot up. However, I know this is not S.O.P., since at work all the Dell GX1's and clones we install 2k server on start up in about the quarter of the time mine does.
My troubleshooting steps:
Install nVidia's newest driver
Install the latest BIOS for my motherboard
Tweak the BIOS video settings again & again
Spend hours upon hours on the web researching

Well, if I do find anything in my quest, I'll be sure to post it here. And I'll keep checking back to see just how many more people get this problem, and in case someone finds a solution.

I just started having the same problem. My computer was running ok, but very slow when opening Device Manager in XP Pro.

I tried to reinstall XP Pro, and after installing some ATA66 drivers the machine locks on boot. Disabling the controller in BIOS allows my machine to boot. So I tried lots of different combinations of drivers and options, got the Windows XP updates, and nothing worked. This is not an IRQ conflict problem as all my devices are using different IRQs. I even extracted a fresh copy of agp440.sys from the install cd, but that didn't fix the problem.

HINT: The previous post about agp440.sys being a red herring is correct. I was able to check the boot log and it does go past agp440.sys. agp440.sys is just the last driver line printed to the screen.

What has partially fixed my problem is moving a CD-RW off of my HPT366 controller. Win XP will boot now, with the controller enabled. This appears to be a 3rd party driver problem in XP. My drivers are not XP signed, but they were working before.

All of these problems don't appear to be directly related so this is most likely a driver related bug in XP.

Hello All.
I'm actually relieved a lot to know that I'm not the last person having this problem. Real big thanks to computing.net for putting up such a good service for boosting my lost confidence!
Here is my part of the AGP440 story:

I own a HP Pavilion 8509 since last 4 years. P III 450 mHz processor with 196 Mb RAM and nVidia graphics card with 8 MB RAM. Literally used every operating system since Dos 6.22 to today's XP.

I went on a vacation and when I was back my system wasn't booting. Found out that some of my friends tried booting the system but failed and tried to repair. After trying to solve the problem for around 11 hours, I suddenly found out that my LAN card had a burned chip on it with a hole!! In the first place, I dont know how it got burnt. And then this AFP problem started coming up. And upon that, HP uses Phoenix BIOS, which doesnt have the options to tweak with as specified by other posts.
Still fighting with the problem. 6 reinstalls, trying to boot with various options diabled in BIOS, booting with various deviced disconnected (including PCI cards and CD drives).. and still fightinhg..

Anybody out there with a HP version of AGP440 problem?? Please, please, help me.

Thank you all very much for all the info here on the site.

i sure will post how I'd solved this problem with help of all you good netizens out there.

FINALLY SOLVED

This is how I solved the problem on my HP pavilion.

After going through all the above posts, I decided that the problem is definitely with the Hadware of my system. As mentioned by other people here, I started disconnecting one unit after the other and booting the system again. The problem persisted until I removed the SD RAMs from their slots and re-inserted them one-by-one. I found out that one of the RAM chips (128 MB) was not functioning properly. I removed it and left ther other two 64 MB chips. Problem solved.

PS: Check the system especially for problems with RAM slots or RAM chips, in addition checking other devices. This damned AGP440 error almost always crops up because of Hardware problems. I feel that windows is not yet mature enough to handle hardware problems.

TRY TESTING THE SYSTEM HARDWARE WITH SELF BOOTING HADWARE DIAGNOSTICS SOFTWARE LIKE BCM DIAGNOSTICS. There are lots of other programs too. Its a better way to check the system for errors.

1. Boot to Win2k CD
2. Booted to the recovery console
3. Type: Disable agp440.sys
4. Reboot.

Your system will reboot, but your video will not display properly b/c agp440 controls your Motherboard video. To see what exacly what agp440.sys does display service in the recovery console.

I will let you know if I figure out how to get the video working again.

We have seen this problem many times. The problem is usually not the agp440.sys drivers but the acpi (it usually starts loading after the agp440.)

We had one system in the shop that worked for months with Win2k, then got the error. Changing the video card helped for awhile but then the problem reappeared. We then formatted and loaded XP fresh. The problem immediately appeared in XP.

Could get in using the recovery console (i suggest that anyone with XP install the recovery console) and then disabling agp440.sys. Which still makes one think it is the agp440.

One article we read happened to mention the installation of the hal would need to be forced to another hal. That worked too.

The best fix we found though has been either updating the bios or updating the motherboard to a fully acpi compliant board.

Hope this information helps some of you.

AGP440 is where it hangs up, not WHY it hangs up. It's a red herring. for me, this was a hardware incompatibility issue. My RCA DCM235 cable modem is not compatible with XP (check compatibility list at microsoft.com.XXX--sorry,I forgot the three letter extension). I deleted cable modem drivers, uninstalled modem, reinstalled lots of other peripheral hardware (mostly USB-stuff), and XP works like a dream. Added back the USB cable modem and enabled to test, and I'm back to blank screens at startup. when I buy a new modem and reinstall XP, I'll be fine.

I personally am not having this problem, but I have done technical support. I've read the posts, and I think I have an idea as to what to look into.

A wide range of video cards, computers, and BIOS seem to be represented here. The only common link I can find is the OSs. Obviously, some people have managed to fix the problem by replacing the faulty file. Others have reported that their system had to make repairs.

In my opinion, this may be related to either faulty CDs, or the program on the CD has a bug. This bug might be triggered by something happening on the machine, causing it to lock up and crash.

Either way, it looks to me as if the problem is NOT with the machines themselves, or any hardware. (Unless there does happen to be a common piece of hardware on these machines which are having conflicts. However, this is very unlikely, given the range of models and ages of the computers.)

As for solutions, all I can offer is trying to use a different CD to do a clean install, or try a different OS. I do admit that I have not worked much with either 2k or XP, so there may be other solutions.

Hope this helps someone, at least. Good luck to all of you.

Well I have had the agp440 hang up problem many times and use to just reinstall the OS (WINXP PRO) on my Dell 8100 to fix the problem. Untill I read all the post on here and got an idea that worked for me.

WHAT HAPPENED TO ME.

I was jsut doing my usual on the web(get your mind out of the gutter) and my laptop froze. I hard shutdown the laptop and powered back up to get the lock up on the AGP440.sys.

WHAT I ASSUME...

While working my video driver conflicted with something else in windows and said #@!@
you! When I powered down that driver became corrupt. The file AGP440.sys was trying to call on the driver and being as it was corrupt could not work with it.

THE POSSIBLE SOLUTION

Before you try any of this PLEASE make sure you are comfortable working in DOS and know what you are doing.

YOU CAN MESS UP YOU SYSTEM AND POSSIBLY LOSE ALL YOUR DATA IF YOU DONT KNOW WHAT YOU ARE DOING!!!

PLEASE READ ALL OF THIS POST BEFORE YOU START.

I first booted to the "SAFE MODE WITH COMMAND PROMPT".

I then worked my way to " C:\WINDOWS\SYSTEM32\"

I then ran the program "CONTROL.EXE" This brings up a confermation window.

Click yes.

Then another window will pop up with your control panel.

I then clicked the "SYSTEM" icon.

I then clicked on the "HARDWARE" tab.

I went to the "DISPLAY" tree and right clicked and selected "UPDATE DRIVER".

Choose "INSTALL FROM A LIST OR SPECIFIC LOCATION(ADVANCED).

Then choose "DONT SEARCH. I WILL CHOOSE THE DRIVER TO INSTALL"

Click "HAVE DISK"

Navigate to your driver.

Choose the approiate driver and let windows reinstall the driver.

Finish.

Reboot.

If all went well and your fingers are crossed. You should get back to your desktop in no time.

I hope this works for you as well as it did for me.
