Nat, it sure sounds like that was the problem, and it would be consistent with every symptom you described.

update. New ram chip put in last night. Server stayed on all night. Keep your fingers crossed for me!

Hi Mr. Bott.
Again, thank you. I did swap out the memory, and it boots with either one in place, and recognizes that there is only 512 present. But I continue to have safe mode crashes, most now with no notation as to cause at all, a couple with irql not less or equal. I found a cpu tester at pc world, but while i was transferring it to cd on my laptop, the server, which was in safe and doing nothing else but waiting, crashed again. What now? Do I give up, replace the cpu and hope that solves it? Your insights appreciated.

Nat, if you are seeing stop errors in safe mode, the cause is almost certainly hardware. When you’re in safe mode, neither of the suspect drivers is being loaded.

I would recommend either (a) running the most comprehensive memory test you can find or (b) remove half the RAM and restart, and if the errors continue then reinsert the RAM and remove the other half and test.

I’ve seen RAM fail in service before. It’s not unusual or unexpected.

Hi Ed.
I found this post very helpful since I had turned on verifier and was in a bsod loop. This post got me out of it. Thank you.

I then went in safe mode, turned verifier on, and found only two unsigned drivers, exifs.sys, which is apparently part of Exchange and shouldn’t be an issue, and filedisk.sys, which was part of winimage which I downloaded yesterday to try and make a seagate boot cd to test the hard drives (it didn’t work). Also, the bsod loop comes back even in safe mode if I leave the server running with verifier on.

So, I don’t think these two drivers are my problem. One is too new and the other is apparently part of the program, although I haven’t been using Exchange. Now what?

This all started because of frequent random crashes. I had the server rebuilt, keeping the cpu, the ram (and adding more) and the hard drives. Since the problems continue, and I reinstalled sbs, and the hard drives passed the Western Digital test I found, I guess I’m left with the original RAM being bad. I’m going to try and test that next, unless I’m missing something with the drivers? Could it be one of the signed ones?

Thanks for trying, this BSOD is a problem, maybe i’ll try the Verifier.

Steve, your blue-screen errors are caused by faulty drivers. You need to find the driver and remove or replace it. A registry cleaner will not help, and I know of no driver-scan sites that will be of any assistance either. Sorry.

Will any of these driver scan or registery clean up sites really get rid of BSOD? I”m getting an error code of OxOOOOOO9c.

Looks like some folks had trouble disabling Verifier. One way to disable Verifier is to:

1. Boot up in Safe Mode.
2. Run “verifier.exe /reset”.
3. Reboot.

Driver Verifier is disabled in Safe Mode.

If you are curious to learn more about Driver Verifier, its documentation is available at http://www.microsoft.com/whdc/DevTools/tools/DrvVerifier.mspx.

I get blue screens of death all the time. Ed, I have no idea where to start. I don’t understand what the hell I am doing, is there anyway we could do some live for of chatting to fix my computer? I am considering going to Macs, please save me!
Thanks in advance!

I experienced the BSOD three times in the past couple of weeks. The last one was an 0xC1 error. I heard about Driver Verifier Manager and checked if any drivers were being monitored. When I displayed information about currently verified drivers, it listed brpar.sys, mpfirewall.sys, scsiport.sys, snapman.sys, tifsfilt.sys, timntr.sys, xmasbus.sys and xmasscsi.sys. I didn’t add any of these drivers to the monitored list. In, fact I never added any drivers ever. How did these drivers get into this list? Can just delete the existing settings?

Thanks,

i have a bluetooth usb dongle which works fine(laptop) until i plug the power lead in,
i then get bsod usb bugcode,would this be the bluetooth driver even though it runs fine on battery supply.

Thank you very much for helping me out with this manual. I had the same problem as RuizdelVizo and it turned out Driver Verifier itself was the problem. No more BSODs for me and again thank you!

I have a problem when I open Excel, I go into reboot
Word and Power Point work fine
Could this be a problem Verifier could help resolve
