I believe it is possible to run memtest86 from a floppy disk if that is any

This sounds almost certainly like a hardware problem.

Try some basic hardware checks:
 - Make sure all fans are running (particularly processor fan).
 - If possible, check what temperature the CPU is running at (sometimes it 
says in the BIOS setup program).
 - Try removing and re-seating RAM, PCI cards etc.
 - If you have more than one module on RAM, try one at a time.
 - Make sure your power supply is sufficiently powerful for the system (on 
each rail, particularly 5V, not just total).
 - Remove all unnecessary components (e.g. PCI cards, extra drives) and see it 
it runs more stably.
 - If you have spares, try swapping out parts one at a time.
