Vista Wont Shut Down

Hello everyone,

I've been having a problem with Vista lately, when I shut down my PC Vista shuts down correctly showing me the usual procedure, but when my monitor says "No video input" ( meaning Vista has shut down) my Computer is still on. Its quite annoying because I have to shut it down with the power button on the case every time. When it started acting like this I thought if i had installed any particular program, but I couldn't think of anything except that i did a Defrag and used Glary utilities or CCleaner (I don't remember which one) for my temporary Opera/FF/Internet Explorer files. So I tried to restore the system to a previous point but it didn't help. After I did a full Antivirus scan with: Kaspersky Online Antivirus Scanner, Malwarebytes Anti-Malware, hijackthis and even RootkitBuster. None of these softwares found anything. I really don't understand whats happening.

I have very few programs that open at startup ( Nvidia Drivers, Audio Drivers, ,Password program and obviously all of the usual vista services) no Antivirus and Vista built in Firewall.

I also have a Dual Boot With Ubuntu ( I'm not much of an expert, but I don't think Ubuntu could be causing this).

If specs could be useful just ask.

Thank you

Hello Arguggi, and welcome to Vista Forums

If it has not been to long a go, you might see if doing a System Restore using a restore point dated before this started can fix it for you.

In the mean time, you can try this shutdown shortcut to see if it may work for better. It forces a shutdown.

Hope this helps,
Shawn

Untill Now i have tried to:

1)Close every program that wasn't from Microsoft, including my razer mouse configurator, my motherboard Audio Drivers and my password program but it didn't help. I didn't close any microsoft services because i wasn't sure if i could damage my pc.

2)Restore the system to a previous point, but i didnt help. When this started happening I hadn't installed or modified any particular programs or windows settings, as far as I remember.

3)Check if my Motherboard BIOS was updated and it was.

4) Shut it down in safe mode, problem still happens.

5) Use a Shutdown Shortcut instead of the usual shut down buttone in the start menu, didn't help

6) Run a System File Checker, no errors found

7) Run a checkdisk on my only Hard Disk, found nothing

For Some reason it shut down properly when i manually closed the windows defender User interface, or something like that. So i tried to not make Defender start when i boot but nothing changed.

I'm really dont know what to try next. Could Ubuntu be causing this maybe?
Any other ideas?
