i had the same problem, industrial PC card P4 800Mhz etc, I’d put some memory in from other machines and thought it was ok, it ran and I went to watch tv, heard the m/c blleping and going through the cycle, rebooting on the aswrvrt .sys as above. So I removed all mem except one DIMM , hey presto it seems to work again. Dont blame windowze immedialty (I always do grrr) when you see something like that it may just be the h/w, think it through…
