mup.sys reboots during bootup

[Highlandish]

any ideas why my friends pc cycles through rebooting on this part of the
boot up?

could it be another problem with the viaagp1.sys file it cant find during
the initial install?

It could be, but you really haven't given us any information about your
friend's machine so we can help you. If this is a clean, initial
install and you are having problems doing the first boot, you probably
have hardware issues. With so little information from you, that's about
all I can say. Here are some links to help you make a good newsgroup
post:

Then do come back and repost with all necessary details. There are lots
of people reading this newsgroup who want to help you (like me), but
you have to give us something with which to work.

actually, I know very little about his machine. it was an initial install
that had problems loading the Northbridge driver for the viaagp, ignoring
that problem and continuing the install gave graphics problems in the fresh
OS. upon rebooting, it then just continuously reboots without ever fully
loading. booting into safe mode displays the drivers and at mup.sys it
reboots.

Here are some general hardware troubleshooting steps. It certainly
sounds like you do have faulty hardware. You could start with the video
card.

1) Open the computer and run it open, cleaning out all dust bunnies and
observing all fans (overheating will cause system freezing). Obviously
you can't do this with a laptop, but you can hear if the fan is running
and feel if the laptop is getting too hot.

2) Test the RAM - I like Memtest86+ from www.memtest.org. Obviously, you
have to get the program from a working machine. You will either
download the precompiled Windows binary to make a bootable floppy or
the .iso to make a bootable cd. If you want to use the latter, you'll
need to have third-party burning software on the machine where you
download the file - XP's built-in burning capability won't do the job.
In either case, boot with the media you made. The test will run
immediately. Let the test run for an extended period of time - unless
errors are seen immediately. If you get any errors, replace the RAM.

3) Test the hard drive with a diagnostic utility from the mftr. Usually
you will download the file and make a bootable floppy with it. Boot
with the media and do a thorough test. If the drive has physical
errors, replace it.

4) The power supply may be going bad or be inadequate for the devices
you have in the system. The adequacy issue doesn't really apply to a
laptop, although of course the power
supply can be faulty.

5) Test the motherboard with something like TuffTest from
www.tufftest.com. Sometimes this is useful, and sometimes it isn't.

Testing hardware failures often involves swapping out suspected parts
with known-good parts. If you can't do the testing yourself and/or are
uncomfortable opening your computer, take the machine to a good local
computer repair shop (not a CompUSA or Best Buy type of store).

what's MFTR?

With this tiny bit of information, I doubt anybody can pinpoint the
problem,

Rest assured, however, that the problem has almost zero probability of
being caused by mup.sys. MUP gets a bad rap, as it's the last driver
to load during boot. Whatever is causing this problem is occuring
after that.

Manufacturer.

"ignoring that problem" ... hmm...

You say it is a new initial install where something went wrong during
the install and that it has never worked right, right?
I'd weipe the installvolume and rinstall (after cleaning the CD) hoping
it was just a bad fluke the first time.
If the same happens again, maybe your friend have a bad install CD.

(VIAAGP1.sys, indicates the northbridge is a VIA chip. If southbridge is
also by VIA, the motherboard driverbundle, that includes the Accelerated
AGP driver, is called Hyperion (aka '4-in-1').)

I'm sure if I had the machine to myself (and installed a floppydrive) I
could fix the thing, or at least narrow down where the problem lies, however
it is a friend, not a customer. I wanted to throw some insightful
possibilities at him on how to fix it himself. on Tuesday I get to see the
machine again, this time I am taking more than software over to look at it.

Quoth The Raven "... et al."<[email protected]> in

Does http://cquirke.mvps.org/sp2intel.htm ring a bell?

That usually applies to lockups after mups.sys rather than restarts.

On many systems, mups.sys is the last listed file during Safe startup,
so it gets blamed for everything that goes wrong between this phase
and the (non-)appearance of the desktop.

On other installations, agp440.sys loads after mups.sys and gets
blamed instead ;-)

I'd check hardware first:
- eyeball for bad mobo caps
- test RAM via MemTest86 or SIMMtester (DocMem)
- check HD for physical defects
- copy the installation CD to HD twice, FC to look for variance

As per last point; expect error copying CD if so.

Might be bad drive, too, so doing the test on a working PC may not
exclude if the sick PC's CD drive isn't used too.

There's a known IDE data loss bug with some VIA chipsets, so I'd read
up on that. It usually presents more insidiously than this, though.

how is it that mvp's don't bottom post to show an example? OE-QUOTEFIX was
brought to us by an MVP so all must be using it...

Well, it is RTFM backwards. I was just telling the truth.

I don't get it. He needs a t-shirt for that?

The front of the manual tells you what the features are.
The middle tells you how to use them.
The end tells you why they don't work.

Guess what I want to know first?

Uhm, yup. Our tri-parish area knows that I own/run a computer repair clinic
and love to ask questions. At the games, Tim wears the t-shirt to say,
leave us alone we are watching the game. )
