Service Control Manager Error

[glennc]

Hello,
Received a Service Control Manager Error "The DHCP Client service depends on the Ancillary Function Driver for Winsock service which failed to start because of the following error:
A device attached to the system is not functioning."
This caused my W7 Ultimate 64 Bit computer to lock up after the control/alt/delete screen. After I hit Ctrl/Alt/Del the screen does not show any users to log in.
According to the event log this has happened before and I have noticed the same issues before. It will reboot in safe mode.
Can anyone give me some advice on determining which device is not functioning as I can't decipher it and could this be a failing board related problem? I have gotten Kernel Power Errors "the system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly." even though the computer was restarted by a program and did reboot, or from a user shutdown or restart in which it did reboot?
I hope this is the correct area for this question and I appreciate any assistance.
Glenn

It sounds like a hardware error to me. Since Winsock is mentioned I would concentrate on the Ethernet interface. If it's built into the motherboard then I don't know how you'd test it except by swapping the whole thing out. I know when I got defective network cards in the past it was one of the few things that would hard lock the machine. The system would come up, but then when the card heated up, the whole system would freeze. Trip back to the computer store. Insert a good card. All is honkey dorey.

Hello MilesAhead,
Thank you for the response!!!! The network is built into the motherboard an MSI 7551. I bought the board and Phenom II 965 processor used.
Do you think that the failure to shutdown properly during a operator or program initiated restart or shutdown might also be Motherboard related??
Really appreciate the help. Starting to look real serious.....

It's hard to say. But the OS by default is set to reboot on hard errors. Is there any way to get the motherboard out of the equation? Maybe by trying to boot the HD in a similar machine, if that's possible. Or temporary replacement MB? I'm more of a software guy on PCs. Most of what I learned about PC hardware was just background for programming in assembler.

Howdy again Sir,
I may have found a causal problem. I have a second Hardrive encrypted with TrueCrypt. It is set to auto boot and ask for a password. I disabled that and few other items from starting up and if hasn't failed all last night and today. I have been restarting and shutting down repeatedly to force a failure.
If this continues, I think I will try replacing the secondary hard drive. My processor is again, not supported so I will have to get a new Motherboard, processor and DDR3 ram..................... Finger's crossed!
Thanks
Glenn
