For the last few days, I've been getting BSOD at random times. Sometimes it happens during startup, sometimes during shutdown, and sometimes at random times while in mid-session.
Attempting to restart after crash often (but not always) brings the message 'no boot device found' and a prompt to insert a bootable disk. Generally after leaving it for a time and coming back later, it restarts OK.
It's an HP G62 laptop with Windows 7 Home Premium 64-bit pre-installed. I bought it around Christmas, so it's only about 6 months old.
Dump files attached, and any hints gratefully received!
