Don't get me wrong, I like ASUS boards, and BX chipset boards were a
very safe choice at the time, that's why this problem was very
disturbing when I experienced it on 2 or 3 boards (out of more than 100,
but I guess many never ran Photoshop since then).

I digged my archives.

Adobe Knowledgebase article about the problem
(http://www.adobe.com/support/techdocs/2256a.htm) mentions spontaneous
reboots with Dell Optiplex GX1, ASUS P2B-F and ASUS P3B-F.

I could not find anything about the problem on ASUS websites at the
time.

(unofficial) P2B-(L)S fixing is documented here:

(unofficial) CUBX fixing (some of those are also affected):
