changing irqs

[nicki]

my motherboard is a,MSI.K7T266 (ms-6380).my graphic card
is a nvidia Gforce 2 PRO/GTS, DDR 64mg.power supply 350 watts.system mem,256 DDR.I'm having mega lock ups in 3d games.running windows 98se is ok. I noticed that the graphic card is sharing, irq 11 with my, pci, network card & pci, irq steering. Would this cause my system to lock if so how do i change irqs.or can someone please tell me what might be causing me so much grief?

PCI devices are designed to share IRQs, so unless there is a hardware conflict in device manager, then this is not your problem. Try updating both DirectX and your display card drivers. If this fails to rectify the problem then my next suggestion would be the display card itself.
