Yes a clean install does recreate a new MBR. But something could be
modifying it. As it seems to stick for awhile and then poof, right?

Most BIOS uses flash memory. And sometimes flash fails. Thus either the
settings won't stick very long or not at all. A weak RTC battery can
also cause similar symptoms, but it is rare it does.

I just worked on an EeePC 702 that couldn't read the SSD (solid state
drive). And I couldn't flash the BIOS either. Pulled the SSD out and
popped a new one and everything worked again. I could even flash the
BIOS. Weird that the BIOS needs a working drive just to flash the BIOS.
Who would have guessed that one?

Yup, you are probably right. Although I wouldn't write it off yet. ;-)
