Hi everyone, this is my first post here so excuse any errors!

I am hoping someone can shed some insight on what is going on here. We have a mass amount of PCs (Dell Optiplex 740s) that are having an issue rebooting. It seems intermittent, and we have no real pattern as to why it's happening. It seems to be after patches, but our other machines seem to be fine. I've run Memtest and chkdsk which have come back with no errors.

I have gotten quite a few dump files from the various pcs and this seems to be the common one amongst them. Just wondering if anyone has seen this before. Any help would be muchly appreciated :) Jaclyn

Well...I think you are making a big mistake...by trying to treat all system problems...as if there is one common element.

Individual systems reboot for any number of reasons...defective hardware, overheating, and malware would be my top 3 picks.

Csrss.exe...if valid, is a critical Windows file. Maybe that's why you get F4 STOP errors, but I would not expect it to be the cause...but rather, the scene of the crime.

A standard definiton for this error, per the Aumha website: "One of the many processes or threads crucial to system operation has unexpectedly exited or been terminated. As a result, the system can no longer function. Specific causes are many, and often best resolved by a careful history of the problem and the circumstances of the error message."

A common element...would mean some app that runs on all systems..or some malware infection (if the systems are networked), IMO.

Generic Info On CClientSvc.exe

If that's applicable to all systems...the finger points that way, IMO.
