I've had my HP Pavillion dv6 laptop since last November - and it has had 8GB RAM and a 256GB Crucial M4 SSD installed since the start.

I use it for software development and it's had a Windows 8 RTM installation since early September.

Yesterday I had to give a presentation at a customer site - so used Powerpoint for the first time since installing Win8... since that point my machine has 'frozen' every 2 hours or so after startup.

There doesn't seem to be any easy to see reason behind the freeze - the system just freezes, even if I have left it idle with just a desktop there.

My immediate suspicion is that the SSD is the mostly likely cause of the problem. I've looked at some of the questions on here - e.g. How do I troubleshoot hardware issues related to a computer freeze/crash? - but don't really want to start taking my laptop apart.

Another suspicion is that this might be related to the WiFi adapter (Broadcom 802.11n) since I have noticed that this doesn't seem to play perfectly with things like Hyper-V in Win8.

Can anyone recommend any software diagnostic tools that I can run in order to evaluate the health of the SSD or of other parts of the system?

Thanks

Stuart

P.S. I doubt Powerpoint is the cause of this, but I may use it as an excuse never to use it again... More realistically perhaps something got damaged during travel to the customer site?
