Laptop freezes on shut down.

[venom0706]

Hello, I am using a Lenovo z510 (i3 4000 M, 2,4 GHz, 8 GB RAM and Geforce 740M) laptop, running on Windows 7 (64 bit). Recently, the laptop started hanging on the windows shutting down screen. I noticed that the loading circle doesn't hang up, it moves, but the OS just doesn't shut down. Which probably means there is a program which doesn't close properly, because the system is still "thinking".

I noticed that the problem started to occur after one time, my Skype couldn't detect my laptop camera. The camera problem got fixed after Skype automatically installed its latest version, but the shutting down problem started to happen. I don't know if it's related, but I think Skype is the issue.

The laptop has the latest drivers for all of its components installed, the GPU drivers as well. No viruses, damaged files or malwares were found when I did the relevant checks. Also did a sfc system error check (no system problems found) and a defragmentation of both my disks. Did a registry clean up as well. None of these fixes the issue. My last resort is a re-install of the OS, but I don't want to waste time and efforts on this.

Any idea what the issue might be? I would really appreciate it. Thank you.

My first hunch always starts with the network drivers in this situation, but being that you mentioned camera driver issues, it could be there too.

Have you checked to see if this occurs when you load/shut down in safe mode (with and without networking)?

The world would have saved lots of wasted time if we all keep back ups of our stuff, so we can just "Go Back." Run RESTORE and see if your system have kept "checkpoints" for restoring.

My W7-64, at times would timeout waiting for apps to close but it WILL timeout and does a forced terminate, a box pops up. I don't remember having done any configuration to tell it to do that so I must assume this is by default. Somethings special on stuff you installed lately.

Okay, I went to the last resourt - re-installed the OS. However, another issue started to appear. Sometimes, when I try to install anything (software, or a driver) the installation would just freeze on a random moment. It doesn't happen always, but when it does, it is annoying. Any idea what the problem might be? I don't want to go through another reinstall of the OS, it is exhausting and I spent so much time installing all my software again... Thank you.
