Can I switch from vista 64 bit to windows xp?

I just uninstalled that driver or whatever, and I booted it up again and I got the blue screen again. Something to do with "MPRIFL.SYS", anyways when I try and install that thing I get this error

I'm using vista x64 (as you probably already know) and its a dell if that helps.

 

Okay, to get video drivers re-installed we'll use Dell's drivers, found here:

And since you bluescreened after uninstalling... that's not the problem. Googling "MPRIFL.SYS" did turn up a bit of information though...
Do you, or have you ever had a program called "Folder Lockbox" installed?

 

I'm installing that right now.
Yes, I do have Folder Lockbox installed on my computer

 

Hopefully you don't like that software too much, because guess what?
That's what's causing the problem. Funny how one little word was enough info to spur the research I had to do to solve your problem.

First, go back to programs and features. Uninstall Folder Lockbox (I would take anything you care about out of those locked folders before uninstalling...)
Then, go to C:\WINDOWS\system32 and delete "Windrvnt.sys"

Also download and install this program and find all mentions of Folder Lockbox and remove them.
And hopefully we'll finally be done.

 

wow I hate that thing, I can't believe that was the problem.
I can't seem to find "Windrvnt.sys" would it be in one of the sub folders?
I even searched for it and no luck.

 

If it's not there it was probably removed when the program was uninstalled.
Is there a "MPRIFL.SYS" present anywhere?

Just let me know if you get another BSOD, but I think you should be good now (as long as you used the driver manager software I linked to)...

 

Nope there is no "MPRIFL.SYS".
Yes, I did install that driver manager tool and I couldn't find anything that had to do with that LockBox.
Anyways thanks so much for all your help and time. I can't believe I found someone like you over the internet that was so nice to help me.

 

Glad to have helped.

Post back if you get another BSOD. If you don't post back in a couple days to let me know that it's solved now.

 

Will do, thanks again.

 

Just got another BSOD

Something to do with:
BAD_POOL_CALLER (thats what it said at the top)

STOP: 0x000000c2 (0x0000000000000007, 0x000000000000110B, 0x0000000000000000, 0XFFFFF88018E61010)
(I think I wrote it down correctly)

 

have you tried to reinstall from the recovery cd ? or does it do this everytime you reinstall ?

 

I don't have a recovery cd. This has been going on for like 9 months now since I bought my computer so I'm not exactly sure if that would help.

 

is the laptop still under warranty?

update here s a link you can go to tha thas that error ur getting now and also has a solution for that error try that and let's see what happens

Do you use this laptop on your lap, or on a table?

My sister had a laptop with a loose RAM slot that would freeze (not sure if it would BSOD) the computer when the computer was being moved around.

 

It's because of that software, it's still got a bad device installed.
I am confident at this point that it is a software error, I think the best thing for you to do would be to just reload the computer.
Do you still have your recovery partition intact? If so, just back everything important up and use the recovery partition.

 

hep. he told me he doesn't have a recovery dvd. i doubt there's a recovery on his hdd. i hope he does have one though.what he needs is a good program that will download and install the right updates for his hardware also.

 

Well, he has a Dell and Dells come with recovery partitions, and I have doubts that our friend has done a clean format, or he'd have the disk to do a reload with! So I feel pretty confident that he's got a recovery partition.

The problem is not that he has the wrong drivers for his hardware, it's that that software lockbox has emulated a device and installed a driver incompatible with the rest of his system. It's gotta be removed. If I was personally in front of his PC I might be able to fix it, but volleying data back and forth can get tiresome. At one point, it's better for the user to just save themselves the headache and reload.

 

As an aside, to get past the validation prompt from Dell/Intel I had to uninstall the driver from Control Panel then restart the computer, then install the new driver. See here: http://forum.notebookreview.com/showthread.php?t=329737

OP might want to try that.

 

Also here is another BSOD I'm getting.

Win32K.sys

STOP: 0x00000050 (0xFFFFF900c3A00010, 0X0000000000000000, 0XFFFFF96000134950, 0X0000000000000000)

 

do you have a partition on your hdd called recovery?

but did you tell me you have been having this problem ever since you bought the computer?
