Hello,

I posted this in the Windows 7 forum as well.

I'm having a problem with my laptop lately and so far I've been unsuccessful in finding a solution on the internet.

Computer:
Dell Inspiron
Windows 7 Home Premium 64 bit

Problem:
The laptop boots without any issues and loads into Windows without any problems at all. When I click to open any program after a few seconds or so the laptop automatically says it is 'Shutting Down' and restarts back to the Windows login screen. This all happens gracefully.

I believe this has something to do with the Networking on this laptop. My reasons for this are as follows:

1. I boot into Safe Mode with Networking and I experience the issue as stated above.
2. I boot into Safe Mode and everything works fine
3. I shut down all services via msconfig, rebooted and the laptop never restarted. Once I activated all services the latop started rebooting.

I've tried updating the Wireless and Ethernet drivers but I still experience the same issues.

I booted into Safe Mode after experience the issue and took a look at the 'Event Viewer' and the Windows logs. Here are the errors that are showing up a lot.

The Network List Service service depends on the Network Location Awareness service which failed to start because of the following error: The dependancy service or group failed to start.

DCOM got error 1068 attempting to start the service netprofm with arguments "" in order to run the server:

DCOM got error 1084 attempting to start the service wuaserv with arguments "" in order to run the server

Let me know if you need more information. I'd appreciate any help you could offer. Thank you!

I have CCCleaner on the laptop. When I run the Registry scan it returns a list of issues. I'm not sure what I'm looking for in this list. Do I just check everything and 'Fix selected issues'?

I also have Microsoft Security Essentials on the laptop.

So I cleaned all the registry errors with CCleaner.

I installed Malware Bytes and ran it which found 4 problems. I cleaned those and restarted. However, it looks like there is a Trojan in the svchost.exe. I remove it and then it just comes right back. Also the computer is still restarting like it was before.

So I may have dug myself into a deeper hole. I ran Windows Defender Offline to clean the trojan. After it was cleaned out and the latop restarted it would start to load windows and then immediatey go to the blue screen of death.

I tired a system restore back to a certain point, now when it trys to load windows it blue screens then restarts.

Well that really sucks. I have a Win 7 Ultimate cd, however this is WIn 7 Home premium. Will it still work? Are there any other ways I might be able to boot back into windows?

This is the error code: Stop error code 0x0000007B

Do you have empty DVD or empty 4 Gb USB? If so, you can download your ISO for free from microsoft.
http://social.technet.microsoft.com/Forums/en-US/w7itproinstall/thread/c0e78d7a-883d-4caa-a8c0-1e127a14612a/

Here you will find links with options to download.

You can use Novicorp WintoFlash program to transffer your ISO files to USB and boot from there. Or you can burn it do DVD if you like.

I downloaded the ISO file for Win 7 Home Edition and set up a USB to boot it from.

So when I boot to it it loads fine, I go to Repair My Computer and it searches for Installations. Says Windows found problems with your computers startup options. I click 'Repair and Restart'. It says 'Failed to save startup options'. How do I fix that?

I executed bootrec /rebuildbcd which found 1 Windows installation at d:/windows. It asked if I wanted to add the installation to the boot disk which I said yes. However it then says 'Register system device cannot be found.' I just can't win.

Really don't know how did you MBR got messed up like that.

Run startup repair again from USB disk. If that doesn not succed again, run normal windows installation and choose upgrade if you get that option. It should leave your programs intact and fully reinstall windows. If that does not succed then i don't know. If you don't have some important data then clean install with format will be your best option. I hope it won't get to that.

I believe I got it to work.

I found the following instructions:

diskpart

lis vol

( Look to see the drive letter for your main windows partition - if it is D then type as below, otherwise replace D with the letter diskpart gives for the main windows partition)

sel vol d

act

exi

bcdboot d:\windows /s d:

bootsect /nt60 all /mbr

I am not getting restarts anymore. I did run the scan again with Malware Bytes and the trojan shows up again. Is it ok to run the Malware Bytes rootkit cleaner?

http://www.malwarebytes.org/products/mbar/

The rootkit scan found 6 malware infections

I believe the restarts arent occurring because the Malware Bytes program has the trojan quarantined. I could be wrong.
