CSRSS.exe Causing BSOD's

4 posts in this topic

Hi Folks!

New user here - I came upon this site while doing a search for the root cause behind BSOD's from CSRSS.exe.

I'm working on my Mom's laptop and today she mentioned (again) that it had a BSOD and if I could look into it. The mini dump section had 33 files of identical size all the way back from November of 2006 to yesterday.

I checked 5 of those 33 files and each one of them seemed to be complaining about CSRSS.exe. I don't know what's causing this issue but obviously it's been going on since the laptop was bought new back in 2006. I've kept this machine literally squeaky-clean over the years and in fact just went through it. It's virus-free and has as many updated drivers as I could find.

Anyway, I've zipped up the last 7 mini-dump files in the hopes that someone might take a look and narrow down for me why CSRSS is actually coughing. In the meantime I've enabled full dump reporting from this moment on should it be necessary for more info.

Any help that could lead me to the underlying cause is much appreciated. BTW, it's not a virus :thumbup The system really is squeaky-clean and all up to date (as far as I can tell). It's Media Center 2005 and csrss.exe is version 5.1.2600.5512. I just did a complete Media Center re-install on my own workstation yesterday and after all updates I have the identical version so it must be the latest.

Thanks everyone!

You really need to at least change the dump type to kernel (and honestly, I'd prefer a *complete* memory dump, as per the instructions in the sticky at the top of this section). Because otherwise, I have no idea what's happening. The dump does indicate that a device was attempted to be accessed that doesn't exist under the hardware_disk category, but that could mean anything (including virtual CD drives, a mounted device, a network device, anything). I need to see the other end of this LPC chain, which doesn't exist in a minidump.

Note that csrss.exe is not your problem, but csrss.exe is crashing as the victim of something else. Again, we need at least a kernel dump, and preferably a complete dump, before we can give you anything from this.

Minidumps are useless, I'm honestly not sure why they're the default option for dump types in Windows - I wish this would change.

Hi cluberti;

Thanks very much for the reply - I'm not a pro in crash dump analysis so it's nice to be able to talk to someone much more familiar with these things :thumbup

After reading the other thread on CSRSS I anticipated your request for a full dump and changed the settings on the laptop to do so next time it coughs.

Question: Do I really need to do this step;

1. Create or set the following registry value:

Key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\i8042prt\Parameters

Value: CrashOnCtrlScroll

Type: REG_DWORD

Data: 1

or is it enough to just enable a full dump when a BSOD occurs?

Thanks again!

No, you just need it to crash. You'd only do that if you wanted to crash it via the keyboard on purpose.
