I'm running xp pro sp3,which is running much slower than usual,the only unusual thing I've discovered is seven things are sharing IRQ9
these are
ACPI
SCSI
WIFI
SB SOUND CARD
USB
RADEON GRAPHICS CARD
CARDBUS ADAPTER

I know they were spread over different IRQs,I've forced the IRQs in the bios but they don't change in the O.S

Change them in device manager - select properties for each device - resources tab - untick automatic settings then you can change them as you wish.

can't manually change even in safe mode,opton to untick automatic settings is greyed out

If windows does not throw up errors, you should leave them. Check other places for the slow down

BTW system is dual boot win98se which allocates IRQs more even.
Also deffo clean,no viruses,scanned with different scanners.
Regardless of performance,why has xp changed from even distribution to allocating all those items IRQ9?

Two Operating Systems two IRQ lists

If You are not getting IRQ conflicts move on to the sores of the lose of speed. most likely programs start at boot
