Every time I try to access the internet, a blue screen appears. It says that the problem has been caused by a file called okfu53.sys and page_fault_in_nonpaged_area. It also tells me to disable the BIOS memory options such as caching or shadowing. How should I do this?

Congrats on your first post to HWA.

These controls are located in a part of the system called "BIOS Settings", "BIOS Menu", "CMOS settings", "CMOS setup" or some similar variation. This should be covered in your user manual.

You usually enter "BIOS Settings" menu by pressing a specific key or keys during the beginning of the boot-up process. The specific key(s) to press are usually mentioned in a corner of the display as the system boots. They should also be in the manual. It is sometimes the "F2" key, or "Del", or a combination like "Ctrl+S" keys.

Once you've entered the menu, you'll see it provides many parameter settings organized in "pages". Basically, walk through the on-screen prompts until you see the settings having to do with cacheing and shadowing.

Every system and even current BIOS version has a different way to present these data, so we generally can't give you a specific keystroke-by-keystroke set of instructions. Again, your user manual should detail this information.

If you don't have a current user-manual, you should be able to go to the motherboard or system manufacturer's website to download a copy. It will usually be in .pdf format which will (in order to be able to read it) require a free .pdf reading application like Adobe Reader or Foxit.

This particular error would typically indicate a problem with memory mapping associated with a peripheral device. I was unable to locate a hit for okfu53.sys, but most likely this is a device driver of some type. The instruction to disable cache is a holdover from old HW and OSs, and is most likely not actually applicable.
Could you check the bluescreen information once again to see if you mistyped the process/service name? Also the actual Stop code would be helpful along with the OS version you are running.

Gerritt is right about that. But, it's still a good idea to simplify the memory environment as much as possible by disabling any added cacheing and shadowing.

It might even not be a bad idea to reset the CMOS to default values, and minimize your hardware configuration until the problem is solved.

ok*.sys files might be associated with Okidata or Cisco hardware.

I'll tell ya, that's one thing I've never in my life of computers seen. Shadowing in the BIOS.
What the hell is it? And why have i never ever seen that in any of the MoBo's I've had?
And the Cache...???? I've had those BSoD's when I started overclocking as a n00b.
Never seen them again . But I am curious as hell as to where to locate the shadowing!



....I'm back, but only as a part-timer... :)

Back in the ancient days of the 386, the cache was not incorportated into the processor package, but instead was static ram located on the MB. At that time the shadow/cache COULD be enabled or disabled via BIOS. Additionally many RAID controllers had cache ram built in, and in some cases (especially when no battery backup for it was installed), it was safer to run them in a CACHE bypass mode.
Like I said, this particular error code was incorportated by Microsoft, I believe first, in the NT 3.1 Advanced Server software which was introduced during the 80386 heyday.

XP Prof OS
Microsoft Outlook (POP not exchange server)
ZoneAlarm Security Suite
AVG antivirus
Free Agent Go peripheral device with Ceedo

This is my first time asking a question on this forum. I have looked through the other replies and found this one helpful but I need to know what to do.

My computer was working fine. I installed an external hard drive (Free Agent) with Ceedo a program that lets you use the external HD as a mobile device. The new hardware seemed to be working okay but I didn't know for sure which files to include on the external drive so I put most of them on it. Trouble is Ceedo synchronizes files and folders (which should not be a problem) but I think that may be what started things going wrong.

I also have AVG and Zone Alarm and they sometimes interfere with each other. I noticed that AVG was doing a virus scan and would not stop scanning even when I canceled it--it would go on and on for days-- i so I uninstalled AVG. Then I noticed that my Outlook email program was messed up. When I would try to send and receive one of my accounts would attempt to receive over 3,000 messages (when there could really only be about 5 or 10 new ones). Also, a sguare envelope icon appeared in the system tray saying the Outlook is synchronizing folders. I researched this problem on the web and followed every piece of advice (unchecking "use exchange server for offline items in properties" on every folder in navigation panel--I don't know how this box got checked in the first place since I don't use an exchange server, but it was checked so I unchecked them all and rebooted. Still this did not work. I checked my account settings, etc. etc. nothing worked to stop the synchronizing process so I just canceled it each time and tried another suggestion. It was still treating my account like an exchange server account instead of a POP. I don't have any mobile devices.

Then I realized that Ceedo or FreeAgent may have given my computer instructions to synchronize these email files so I decided to eject and uninstall Ceedo but it would not allow me to eject it or use the safely remove icon. It said that the device could not be stopped. I removed it anyway and uninstalled Ceedo and FreeAgent (with add remove programs) and rebooted. The email problem still persisted.

Except for my email problem, everything else seemed to be working normally so I decided to ignore it for awhile (I had spent a whole day trying to correct it). However, a short while after I continued my work I got a blue screen error message saying that windows had shut down to protect my computer. It also said that if this happened again that I should disable Bios memory caching and shadowing. This has now happened two times. I don't have the stop error numbers and don't know how to get them unless it blue screens again. Is there a log of these somewhere?
So. . . .
I have two problems now. 1. How to stop the send/receive synchronizing files problem and 2. How to (or whether to) disable BIOS memory caching and shadowing?

Well detailed posting.
I don't have any specific knowledge of Creedo, though this seems to be the issue with your system.
I'd like to point you to:
http://www.seagate.com/ww/v/index.jsp?locale=en-US&name=ex...ee0a0aRCRD

If you did not have any issues there or if you could not find an answer then:
http://seagate.custhelp.com/cgi-bin/seagate.cfg/php/enduser/st...faqid=3535

If neither of these is good, then you need to hack the registry.

This thread sounds like a problem I have been having.

My laptop (please see configuration below) crashes and shows me a blue-screen with the message:
"A problem has been detected and Windows has shut down to
prevent damage to your computer”. It states it is a driver or hardware
or software problem and that I should disconnect devices to determine
what is wrong. The screen also says to disable BIOS memory options
such as caching and shadowing. Technical information is given such
as:

Stop: 0x0… etc. MULTIPLE_IRP_COMPLETE_REQUESTS
(of course now that I want to provide the exact code I can’t get the computer to crash and I don’t remember it!)

I can’t identify any consistency in the crash. Sometimes it happens immediately at boot after the operating system to start is selected. Sometimes Windows comes up and the crash happens without warning. And sometimes a Windows screen “The system has recovered from a serious error…” is displayed twice and the system runs for a while before crashing.

I ran CHKDSK and no bad sectors were found. I tried to run a DEFRAG but I got a message like “…defrag can’t be performed, an inconsistency was found in the file system, run CHKDSK or SCANDISK…”

I ran a security program (Symantech, not latest version) and no virus or malware was found.

I thought it might be the result of unsolicited Internet traffic by an application. But it seems but I’m not sure that the system runs longer before a crash if the laptop boots connected to the Internet. Crashing still affects the computer when it is disconnected from the Internet (but the application not being able to communicate in this case might in itself trigger the problem).

Ideas I read on the web are:
- install the latest or some specific generation of the driver for some hardware (which? In the case of the problem I read it was the driver for the Intel Application Accelerator for Windows XP)
- disable certain options within the BIOS (which and how?)

This from Dell and it works for me. Dell XPS 400 with XP. Physically open your computer with the power off and remove and reset the memory strips. This way you don't have to go through the system software to solve the problem. If you want to use the system software solution look at the rest of the replies on this topic.

Mine has the exact same problem.. the blue screen comes every time i turn on my webcam device & sometimes even when i start up the computer...

also when i try to run fix disk in the drive c properties it blocks me from doing so, same with the defragmenter saying "defragmenter could not be started" or w.e something like that..

i really want to fix this & i've tried many ways to fix it...

what should i do?

In the May to Present postings on this error, you are most likely looking at multiple virus/malware infections that work together to mitigate cleaning by any one vendors removal process.
My Spouse was foolish enough to let her virus protection updates lapse, and ended up with the same type of issues.
1. System boots, but then hangs almost immediately.
2. System boots, but will not permit a login if you delay the login request long enough for all the identified services to start.
3. System Bluescreens upon any access of any service/process.
4. Even upon booting in safe mode, get a mixture of the above issues.
I had to undertake a reinstallation of the OS in a DIFFERENT directory, and a reinstall of ALL programs. Luckily there was no rootkit issues. The Data is still there, and imbedded deaply in the archive.pst there is an additional injection source, so I've not been able to get her access to her stored emails as of yet.
She kept using the computer for weeks after the initial infection, so kept getting even more.
Some of the malware out there is cooperative now. In the past, a single vector was for a single piece of malware, but the orginized crime units in Eastern Europe, as well as elseware are sharing code to increase penitration.
DO NOT USE AN UNPROTECTED PC.

I have gone to F12 when the computer is reestarting but I did not find anything that says cache, caching or shadowing

What to do?

Unfortunately during i'am using it a big blue screen apper, with the same sign: "disable bios memory options such as caching or shadowing."

It show this information:

*STOP:0x000000c5 (0x00000634,0x00000002.0x00000000.0x8205987B)

I've been having the same problem. I'm really confused about the previous posts, which makes me feel kind of stupid. I have windows XP on my laptop, and on the eeror screen it showed : 0xC0000005, 0x80998CE7, and I think 0XAC048010. I'm sorry to be any trouble, but is there any way to explain it step by step that is easy to understand?
