Just in case anyone comes across anything similar...
Over the last couple of weeks I was getting regular crashes in Steam games. At first I thought it might be pushing my overclock too far, but I reset everything to defaults and still got the crashes - in fact they got more regular. Eventually last night Windows failed to boot when I rebooted after a crash (hung at Windows logo).
I tried safe mode boot and that hung at loading the "classpnp.sys" file for about 4 minutes, then eventually booted to safe mode (I assume if I'd waited this long for a normal boot it would have booted also).
Googling the error and classpnp.sys hang there seemed to be some driver conflict basis for this error and this got me thinking.
The only recent change on my system was that recently I bought a second SSD drive to run my games from. with this in mind I changed the SATA port that the new drive was running from. Originally I had connected this to Intel port 2 on my motherboard (boot drive is on port 1). I moved it to a Marvell SATA port.
This has instantly cured the issue and also increased the SSD drive performance in Crystal by 25%. Games no longer crash and I'm back to my full stable overclock.
The storage SSD was the Crucial V4, boot SSD was OCZ Agility. I'm thinking maybe that either they conflicted, or the SATA2 Crucial SSD didn't like the Intel SATA3 drivers.
Hope this helps if anyone else searches for the issue some day!
