Set "Automatic Updates" to Disabled for now and reboot; this could be an issue as when it fails it can cause other services to fail as well. There is a fix for it, but let's test first to see if it is involved.
I am uploading a zipped copy of the cryptographic service registry key Download it, unzip it and double click and confirm the merge to the registry. Reboot and see if it starts and stays started.
The Black Viper site here has a list of default service configurations. Let me know which ones you have that cannot be set to their defaults. A blank status window just means it is not started. Most of the ones on "manual" will be that way.http://www.blackviper.com/WinXP/servicecfg.htm
Also can you upload or copy paste a log of "silent runners". You will need to download the vbs file to your desktop or other convenient location and run it from there.http://silentrunners.org/
