|Well if the BSOD error is appearing immediately after a fresh install on to re-formatted partition, I am led into thinking it must be faulty or incompatible (old) hardware somewhere in the system.|
Most references I've looked at refer to it being one or more corrupt system files. The only way a fresh install can get corrupted before downloading anything (ie a virus) is either with bad RAM (which you say you've tested already) or a failing hard disk with (for example) a large number of permanently damaged sectors.
If you haven't done so already, I would test the hard disk with the disk manufacturer's own diagnostic utility. Give me the make of the disk (model number not required) and I'll post the necessary web-link. After that I can do no more to help you with this.
This particular error is apparently one of the hardest to nail down to a specific cause.
