Update on my problems ,I moved the modem up aslot to slot 3 & that cured the BSOD probs & is ok now

,I guess it didn't like what it was sharing the IRQ with
Re sound probs ,I updated the sound drivers from the latest drivers available at
Cmedia & the sound now works fine

.Btw Asus do not have any recent drivers avialable at their website atm!
As for the sound quality ,its ok but its not as good as my old Creative AWE 64 that I had ,whilst music sounds fine some sound effects sound slightly disorted ,hard to explain exactly how!

The reserved setting is supposed to be for XP's & there thermal diodes but there is a problem with it ,nearly all users I have seen report temps say they get between 49-50C constantly regardless of load(me included) ,hopefully a future bios update will sort this.For now I have set the jumper to Athlon & I now get varying temps with varying load,though it is fairly slow to respond ,so it would seem it is now using the external cpu sensor.
With a GW FOP 32 I get max cpu temps of 48C with a case & room temp of 25C ,this is with my XP 1500 o/c to 1.45GHz
