4760 - Can't find OS then MUP.sys error

post #1 of 9
Thread Starter 
My neighbor bought a Sager 4760 for college through PC-Torque at my suggestion. He isn't the most tech-savvy, so he calls me when he has a problem.

He said he woke up, turned on his comp, it made a clicking sound, started to boot and said "Operating system not found" or something to that effect. He took it to the campus tech support folks, recreated the error, and they said his hard drive probably crashed. He called me to find out about return options and procedure and I explained the RMA stuff but asked to take a look at it over the thanksgiving break to see if there's anything I could do.

Well, when he brought it over today, it started to boot. It got to the WinXP splash screen with the Knight Rider thing on the bottom, but then it rebooted without notice. It brought up the "safe mode" screen and I selected "safe mode with command prompt". It proceeded to list all the drivers it was loading and hung at MUP.sys. I can't remember if it rebooted on its own or if I had to ctrl+alt+del. Anyhow, I searched MUP.sys on the internet. The solutions I found had to do with everything from USB 2.0, to the BIOS (on this forum concerning Alienware), to a faulty CD-Rom. I tried disabling the USB controller in the BIOS but it still wouldn't boot all the way into windows.

I then put in the recovery CD to try to do an overwrite on the windows system files (repair?). The repair console just gave me a bunch of commands like format and fixboot, but nothing to actually reinstall. I did run chkdsk, which found some errors on the disk, but, unlike scandisk, there was no option to try to repair the errors.

Convinced that the HD was the problem, I thought about trying to pull out the HD to get the data onto another comp and then sending in the whole thing for a replacement HD. But, before I did that I searched MUP.sys in Microsoft's Knowledge Base. It told me that the "Multiple UNC (uniform naming convention) Provider (MUP) is a network resource locator that runs in kernel-mode memory in Windows NT." Since applications use UNC or WNet API to access resources on the network, this gave me the idea to check the internal wireless. I switched it on and pressed power. It booted into windows!

So, the comp is working now. However, I'm still quite curious as to what was the problem, and what I should do about the errors on the HD.

Any ideas are appreciated.

It seems as though the HDD is failing. It happens. I believe the command is chkdsk /F from a command prompt. it will complain about not being able to run because the disk is in use and will ask if you want it to run at next boot say yes and reboot. After it fixes the problems back it up and hit up sager for what they want you to do. Just my $.02 but I'd wrather repalce the drive and be done with it. When windows can't find the os it's gonna be a long day. Best bet is to ghost it to another drive or make an image even better. That way when you get it back you pop it in the other machine and ghost it back. The only problem is that ghost makes a bit for bit image which means if files are corrupt on the original it will be corrupt on the image.

The HDD needs to go to the ICU or the graveyard...

Get it replaced...I think you should be able to get a new one under warranty but ask Sager if they will cross ship the new drive to you (unlikely but give it a shot)

Cheers!!

Yeah, there could've been more than one problem, but if the hard drive clicks or clangs louder than normal or longer than normal, you have a problem.

if u want another input, i was unfortunate to buy 2 ibm 75gxp drives in 2001. both of them failed within a year. there was noticeable and unpleasant clanking, scraping sounds from the HDD's that accompanied their demise.

Has the computer been functioning normally since then?

If you do a chkdsk on three subsequent days, does it discover more and more problems?

I believe that there are shareware utilities on the net that can check drive functionality, have you tried any?

I had various initial issues with my computer which turned out to be software and cable related. But, before finding the cause and solution, I almost sent it in for repair which would have been a waste.

Yes. I ran chkdsk /f and it went through the 3 steps upon reboot, but it didn't linger after it was finished long enough for me to read what it had done. Running chkdsk at the command prompt says there's are still errors on "Volume: Bitmap"

Thanks to those who suggested we trade in the HD. That will probably be the route we take when Christmas break rolls around. Right now, as finals approach, my neighbor has decided to just back up his files and hope for the best.

The HD lasted until today. Now, when we boot we get a long pause (15 secs?) at the bios statistics screen, and then a blank screen with "No Operating System Found". This sounds like the error he had back in November. The BIOS claims his Primary Master drive is "none". His CD/DVD appears as Secondary Master. I checked the HD cables and they are secure. I tried to boot with some Partition Magic floppy disks I have, but it says it can't find the specified drive.

I don't notice any unusual hard drive noises, but I don't know if it's spinning or working at all because I haven't turned the thing over while the system was on. I think this month marks 1 year. Any suggestions besides "Hurry up and send it in while it's under warranty!" (though I'll take those too )?
