it's to do with irq's or device drivers.

firstly, and most importantly, in most cases you must run standard pc mode.. .... find out more about all this on www.musicxp.net (installing xp tips)

the best thing is to check device manager and see if there's a load of things sharing irq 9 (3 or 4 is normal but any more than that and you should worry). if so chances are you are running in the wrong mode. you must reinstall windows from scratch in the right mode.

are you still running your 828 on a firewire card?

check the driver that seems to be the problem near the bottom of the blue screen...

if it's motu.sys or ochi.sys, then it's a firewire problem. this was my problem for a long time until i sorted it. make sure you're running a texas instruments firewire card (check in the device manager). if you are, the drivers need to be rolled back. this solved my problems instantly. you can do a search on the net for the older versions of ochi.sys and 1394.sys. if you can't find them, pm me and i'll e-mail them to you.

then you need to replace these files in the windows>system 32>drivers folder. but do it in safe mode or it won't replace them. xp is crazy - if you replace a driver file with an older one it doesn't like it and automatically updates to what it wants it to be. crazy i know.

if it's not the motu or firewire that seems to be your problem and you're getting IRQ_NOT_LESS_THAN blue screens because of something else, but careful to note down all the info that comes with the blue screens. post it here and i'm sure we'll be able to help.

also go into device manger and see what is sharing the same irq's. post that info here too.

as a rule of thumb make sure all soundcards are on irq5. usually messing about with different pci slots can achieve the required results if you're having problems. or of course you can force it to have a certain irq but that comes l8r in sorting out this problem of yours... hehe...
