Have you checked your power supply? One of the commonest causes in my experience - even when they appear to be working fine.
Yup. Power supply seems fine as does the ram, the motherboard and the CPU. I have narrowed it down to Hard drives and will be installing windows on SSHD to see if it is my SSD that is the issue.
Thanks.
I had a bad HD once causing me BSOD's. Turned out the boot sector was imploding randomly which was locking it up. Ended up installing a new HD and completely reformatting, fixed it completely.
