Windows 7: random BSOD when browing directories

random BSOD when browing directories


I have an issue with my PC whereby it randomly crashes with BSOD after constantly browsing through several directories for between 5-15 mins using windows explorer. More specifically, I produce music, and when browsing through my samples library on my hard drive, and randomly listening to the sound files, after roughly between 5-15mins of browsing, I will double-click on a directory, and my PC will freeze momentarily and then crash showing BSOD. This only happens when I've double-clicked on a directory (folder icon). This has also happened when I just browsed through folders (without listening to any soundfiles). However this is happening very randomly. I have two HDDs in my PC and this happens when browsing through both individually. I have refrained from browsing through files/directories using windows explorer for several days now and my PC hasn't crashed once. I have also selected a slower CPU setting within my BIOS, everything seems to be stable for now.

The BSOD show various information and then reboots my PC, when back into windows I am able to view the following info in dialogue box:

OS Version: 6.1.7601.
Locale ID: 2057

Additional information about the problem:
BCCode: 3b
BCP1: 00000000C0000005
BCP4: 0000000000000000
OS Version: 6_1_7601
Service Pack: 1_0
Product: 768_1

Within the BSOD it mentions that cause may be due to the file: ews88wdm.sys, which I have researched, and found that this is related to my Terratec Phase 88 soundcard. However, I have no other problems occuring with the soundcard or PC. I checked IRQ assigned to this soundcard and found that it is shared:

Attachment 171026

I am unable to manually allocate a different IRQ for my soundcard as the option to change it (within the properties/resources tab) is 'greyed-out'. Could this be related?

I am suspecting that it is an issue relating to my soundcard, I have updated my driver, and tried older driver versions however this has not made any difference. However I am unsure as to whether it is a hardware failure or software related failure.

Please see attached file: related for further details. Any help would be greatly appreciated.

Hi sar23 and welcome to W7 Forums

There are a number of things you can try. First of all, if you are overclocking (or even underclocking), try returning to the default settings. Secondly, do you have another PCI slot to insert the card?

It could, of course, be a driver issue. That is quite an old soundcard you have. See if these drivers help (you might need to install in compatibility mode).

I have tried to do the above but it hasn't made any difference, this is what I have done:

- set CPU to default speed, i.e. no overclocking or underclocking
- moved my soundcard into another PCI slot
- reinstalled drivers (latest version from Terratec weblink above)
however Terratec only supply you with driver files, not an executable program and therefore compatibility mode
cannot be applied to the driver files
- moved HDD sata cables onto different sata ports on motherboard

The PC crashed in the same way as stated in my original post.

Does the additional info in my original post give an indication as to what is happening? i.e. the BCCODE, BCP1, BCP2 etc. I'm unable to find any reference info on the web or Microsoft website.

Thanks for the help, I've just bought a new soundcard instead, hopefully there will be no more BSODs

There have been no more BSODs with my new soundcard. I bought a MOTU audio express, and would recommend it to anyone whose budget is around 300. Everything is running very stable.

I have a feeling that the cause of the BSODs was due to the Terratec soundcard being very old and therefore not stable when running with Windows 7 x64.
