OK, the latest fashion is irql_not_less_or_equal 0x0a
I have attached the minidump just in case but (as long as I could see), it says nothing of value (ntoskrnl being the perp as usual)
I'm preparing for a clean re-installation now - I just hope this will solve the problem.
If not, I'll try a memory-stick change as a last resort (although, I doubt this is the problem).
Anyway, thanks everyone for your help!
