Windows 7 hangs on shutdown

[thegatekeeper]

Hi guys, I have been having this random problem where my computer fails to shutdown every time. I know it is a general question but I have no idea why this happens. The only thing I remember changing was my sound card, but it is disabled in the device manager so I don' think that is the issue.

Is there any way I can log events to see why it is crashing?

Thanks.

Search for "event viewer" on your PC.

Where should I look in event viewer?

Gonna try that program.

Still can't find out why...

I just tried and it crashes in safe mode too. Does this mean it's a hardware problem?
