Hi, just popping in to answer a few of your questions :)
I haven't tried clearing CMOS, mainly because the video card blocks my access to the battery and I'm reluctant to mess about with PC innards unless I really have to. Would this actually help?
It
may help. I usually reset the CMOS after I add or remove hardware, or mess with the BIOS settings a lot when troubleshooting a memory issue and I have to constantly switch timings, voltages, etc. In case you do not know of course, clearing the CMOS essentially brings the BIOS back to default settings. The most important part however of clearing the CMOS is the rebuilding of the DMI Pool. The DMI Pool is a table that is used by the OS to determine which devices are available.
If I am helping a user troubleshoot BSOD related issues, and it's starting to lean towards hardware being the issue based off of evidence, and possible evidence for memory (memory corruption, etc) I always recommend a clearing of the CMOS before running a Memtest to ensure the memory will or will not be stable at default settings.
The final step they suggest seems way beyond my comfort zone, I've never tried mounting or dismounting a motherboard (I'm guessing they are checking for short circuiting with the case).
Most likely. Do not fret, uninstalling and reinstalling a motherboard from a case is not difficult, but as always, just be very careful.. you don't want to cause ESD to the motherboard. When removing the board, ground yourself.
I recall that you can run Windows for a while without activating it, might be wrong about that though.
Correct.
Also, your cooperation is worth noting, and for that I'm sure we all thank you. You're the kind of person we analysts dream of assisting :lol:
