Hi, You may analyze them with Debugging Tools by yourself. You can install it and it’s Symbol Packages from the following link: http://www.microsoft.com/whdc/Devtools/Debugging/default.mspx WinDbg will tell you the possible cause.

autochk program not found - skipping AUTOCHECK STOP: c000021a {Fatal System Error} The Session Manager Initialization system process terminated unexpectedly with a status of 0xc000003a (0x00000000 0x00000000). The system has been shut down. I have tried the startrep.exe bootrec.exe /fixboot etc. When searching for the file through "Repair your computer" command prompt I can see autochk.exe sitting in the system32 folder, but for some reason when booting it doesn't find it. Any suggestions?

1. What has happened before the BSOD? Sometimes the revealing history may help. Any driver, update or application installation? 2. Look into minidump/dump memory. This may give you more information.

The last thing I did was updated BIOS on all servers and Firmware on a storage controller through the Intel Modular Server. All the other servers came up fine, but this one I can't even boot into safemode.

Hi, have you went through the repair process and completed? may be you can try that option. if that also fails, only left option is for you to re deploy the Server. seems to me the problem related to OS Crash. you should be able to run the Repair process to fix it. Thamara.

Yes I have run the repair option. I either get a message saying it can't be fixed and send to Microsoft, or when doing the sfc I get an error saying that a repair is scheduled and to run it again after restarting the server. The only thing I wonder is if I can reinstall over the current OS without losing data.

you may be able to re install the OS over the existing one. But the's a huge mess. only situation you should do that is to copy what ever the data from there and format it to install a clean OS again. Thamara.

There is upgrade option. Insert installation DVD /w SP go through Install and instead of new installation take Upgrade option. This will remove some components like IE9. Next time - upgrade BIOS and firmware if you really solve a problem. Otherwise you tease the tiger. I would recommend to test HDDs in RAID. Chance is that upgrade revealed a problematic disk.
