rgodart 0 Posted March 16, 2002 I'm getting the above BSOD every hour. I don't understand why, the computer has been running fine for about a week and now i keep getting this error.

Nemesis 1 Posted March 17, 2002 rgodart, This is the general KB from Microsoft: http://support.microsoft.com/default.aspx?scid=kb;en-us;Q275678 Not much help though, CLASSPNP.SYS is part of the OS. You could try re-applying the latest service pack, but my experience with STOP 0x1E messages is a clean install. Share this post Link to post
kg5uc 0 Posted August 21, 2002 I'm having exactly the same trouble, though my system has been up and running for around a year and a half. It seems to me my problem started when I contracted a virus (from what source I don't know...I'm very careful about such). I'm hoping Nemesis is wrong, but I'm getting to the point that I think that's going to be the only way to take care of the problem. I've tried a couple of Warm-Reinstalls and it didn't help, nor did anything else I've tried. Good luck! Share this post Link to post
rchhabra 0 Posted November 11, 2002 Hi guys! I'm also a victim of BSOD KMODE_EXCEPTION_NOT_HANDLED classpnp.sys - every 60 min. System Profile - Win2K Pro on a PII, 350 Mhz, 384MB RAM, 2 HDD (IDE-1 30GB Maxtor Ultra Max Plus ATA/100 DMA and IDE-2 8.4GB Maxtor UltraMax ATA/33 DMA) - HDD connected on Maxtor/Promise Ultra ATA/100 Adaptor Card. - OS resided on 30GB HDD in 4GB partition. Have tried the following solutions, but no avail. 1. To begin with, I installed Win2K Pro SP1 last year. No problems (related to above error) until last week when first attack of BSOD happened. Thought it was firewall, got rid of it. Problem persisted. ( 2. Checked MS KB, found an article 311278 related to STOP 0x1E errors and classpnp.sys - solution was to upgrade to SP3. While doing upgrade, system crashed and had to clean install Win2K with SP3. One hour later, the same BSOD with STOP 0x1E error in classpnp.sys eek ( 3. Went back to internet, found that error is related to Maxtor HDD's SMART technology. Downloaded Maxtor's Powermax diagnostics software to check HDDs. Found that my 30GB HDD had SMART problem. Waiting for replacement at present from Maxtor (thanks for their promptness) eek ? 4. So, migrated the system to 8GB HDD with clean install of Win2K SP3. One hour later, the same BSOD. ? ( cry Any solutions? My weekend's been destroyed by this silly error. Some say change the location of controller card to different PCI slot, I might try that. Also, I've downloaded new drivers for Ultra 100 from Promise Technologies website. These are my only weapons left. Any ideas to get rid of my misery? Would XP help? Thanks in advance.

Jerry Atrik 0 Posted November 11, 2002 seems odd that every hour on the hour the error occurs. what happens once an hour. scheduled task?, time check? power management turning the hd's off bios power management turning things off screensaver? Share this post Link to post
rchhabra 0 Posted November 11, 2002 Jerry No scheduled tasks every hour or screen saver. I've done 3 clean installs of Win2K SP3 Haven't had a chance to play with power console, but doubt that causes anything Computer could be idle or in the middle of executing some program, BSOD comes up with the exact same error by the clock. In past, I used to get errors (not STOP errors) with Ultra, but they seemed to have stopped and given way to this new periodic phenomenon that seems to exist for other users too (see above). Any ideas? ? Share this post Link to post
zmlb20 0 Posted January 10, 2003 I am a SURVIVOR of the "hourly BSOD - KMODE Exception not Handled - classpnp.sys" nightmare! I've been scrouging through all the boards on this subject since it just started happening last week. Rchhabra - thanks for the suggestion of up[censored] the Promise driver. It worked - the machine has been on all night without one BSOD!

pprlb 0 Posted March 6, 2003 I too was a victim of the dreaded hourly BSOD. I finally narrowed the problem down to 2 things Hard drive and controller. I have a Fujitsu 40GB hard drive and the Maxtor ATA/100 add-in card. The first problem was that I had an out of date driver on my Maxtor card. The second problem was that my hard drive was sending SMART failure prediction codes to the controller. With the version of the driver I was running, the SMART failure was not handled correctly, causing the BSOD. I went to Adaptec's site and downloaded the newest driver for my controller and installed it. The BSOD went away, and the SMART failure was logged into the event viewer properly. (It occurred exactly an hour after I rebooted from installing the new driver). Incidentally, after up[censored] the driver, I only got the SMART failure once and no more. The system ran all night without any more errors at all. Hope this information helps!! Share this post Link to post
