Windows 7: BSOD computer crashing randomly, twice with BF3, once in Firefox 2day

This has been going on about 2 weeks, I have rebuilt twice, and this issue keeps returning.
I have attempted to follow suggestions on this forum, I have updated my asACPI files, (I think it was behaving worse prior to this); however after restarting it crashed again.
My main partition is on an SSD; after the BSOD the computer will not boot, it either keeps resettings or BSOD, on the odd occasion it can't find the drive, and complains of missing bootldr press ctrl-alt-del. after turning the PSU off, and purging power from the system (pressing on off button until all led's switch off). then next boot it will progress into windows.
At the last occasion I was running Chrome, Remote Desktop.
I have enabled the mini dump, and I am awaiting my next crash. so I can post that.
I am enclosing my sf .zip hoping somebody can help.

Welcome aboard

Your crash dumps are not showing any finite probable cause. In such a situation, it is better to enable Driver Verifier to monitor the drivers.

Driver Verifier - Enable and Disable

Run Driver Verifier for 24 hours or the occurrence of the next crash, whichever is earlier.

Let us know the results, with the subsequent crash dumps, if any.

Also can you please post the info outlined here - Windows Genuine and Activation Issue Posting Instructions

Ok,
So Yesterday after I posted, it was 100% reliable, thought maybe I had it. Today I have been proved wrong.

I have updated my Crucial M4 SSD Firmware,
After about an hour my PC died again. It's taken approx an hour to wake it back up again.
THE MOTHERBOARD Keeps losing the SSD. that seems wrong to me. (Bootldr missing Ctrl alt del to continue).
Next post hopefully dumps.

This is as seen , a Stop 0x74.

Boot into safe mode, disable Driver Verifier.
Then try Advanced Boot Options, Last Known Good Configuration.

If still not fixed, try a Clean Reinstall - Factory OEM Windows 7.

But, what about the thing asked? Windows Genuine and Activation Issue Posting Instructions

Thanks for the help guys, after all the crashes chckdsk had cleaned a few important windows files, decided to cut losses and start again (3rd try at a clean install wish me luck) put primary SSD onto a different sata cable and port.
step 1 install AV Client.
Solved-ish until tomorrow probably,
