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
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?
