Random BSOD's

Here's an extract from the stress.txt file:

WHAT TO DO IF A PROBLEM IS FOUND?
---------------------------------

The exact cause of a hardware problem can be very hard to find.

If you are not overclocking, the most likely cause is an overheating CPU
or memory DIMMs that are not quite up to spec. Another possibility is
you might need a better power supply. Try running MotherBoard monitor
and browse the forums above to see if your CPU is running too hot.
If so, make sure the heat sink is properly attached, fans are operational,
and air flow inside the case is good. For isolating memory problems, try
swapping memory DIMMs with a co-worker's or friend's machine. If the errors
go away, then you can be fairly confidant that memory was the cause of
the trouble. A power supply problem can often be identified by a significant
drop in the voltages when prime95 starts running. Once again the overclocker
forums are a good resource for what voltages are acceptable.

If you are overclocking then try increasing the core voltage, reduce the
CPU speed, reduce the front side bus speed, or change the memory timings
(CAS latency). Also try asking for help in one of the forums above - they
may have other ideas to try.

The point here is that I wouldn't try any of it until I fix the SSD issue - as it can be the cause of the problem.

See, I told you I wasn't familiar with SSD's! :)
Seriously tho', there's an issue with your other HDD - so I'd suggest disconnecting it to prevent further problems from affecting your system.

Then, once it's removed (both the power and the data cables), then rerun Prime95 to see if you get the errors again.

Sorry for the delay - I've been sick and then the neighbor nicked our cable with his lawnmower.

I'd disconnect the data cable from the motherboard, and the power cable (from the PSU) from the drive. This'll rule out any problems with the data cable also.

Zip up and post the memory dumps that happened with the drive disconnected. We'll see what they say and move on from there.

There's many different reasons for a BSOD not being captured. When does the crash occur (in relation to the boot process - before/after the Windows Splash Screen, before/after the Windows logon/desktop, etc?

When the next one occurs, please capture this info from the screen:
