Windows 7 64 bit - Random Freezing
I have a network with about 15 computers all running Windows 7 Professional 64bit SP1. They are connected and joined to a local domain running SBS 2008 on a VMware server (ESxi).
Three computers on the network are experiencing random freezing where I have to manually shut the computers down and reboot them. The freezing happens 1-3 times every hour and doesn't seem to be related to a specific action or application the user is doing or working with. It started with just one computer and after scanning for viruses running hardware diagnostics with no results I figured it still must be hardware related. Then the exact same problem happened on a second computer... and now a third. Don't think it is a hardware problem anymore.
Event logs are mostly clean. I did see one error event id 1001 bugcheck error 9087.
Very strange...

Overclocking and memory related problems don't make any sense... first of all it is happening on 3 computers not just 1. Secondly these are Dell computers and have never been overclocked. They have been stable for the past 2 years and now all of a sudden 3 computers start freezing? Sounds more like a windows update or something of that sort...
Were they always Win7 64 bit or have they been upgraded recently?
ASKER
Always win7 never upgraded.
I would check for driver upgrades starting with video. The other PCs all running the same set of software? Anything unusual about the ones that crash compared to those that don't?

video driver not recently upgraded just checked... other PCs are running same software. Nothing unusual that's why this is so weird.

Looks like a service which automatically started at startup caused the problem. I am still determining the exact service but basically I went into msconfig and disabled all services at startup except the Microsoft ones and the problem went away. I am now in the process of enabling all services one by one until I figure out which one caused the system to freeze.
