I was having issues with system freezes after trying to install a couple of different PCI cards; one was a USB 2.0 card, and one was a 56K modem. After talking to a couple friends, it seems the issue is related to IRQ conflicts. The soyo motherboard has onboard sound, LAN and USB, and all of these are sharing the same IRQ, along with the video card and any new PCI card I install, regardless of the slot I try to install it in. Right now, I have removed the two separate cards mentioned above, but there is an IEEE1395 card installed, and it is sharing the ever popular number 11 spot, though it doesn't seem to be causing any system instability like the other cards:
IRQ Number Device
9 Microsoft ACPI-Compliant System
11 RADEON 9500 PRO / 9700 (Omega 2.5.76)
11 VIA OHCI Compliant IEEE 1394 Host Controller
11 Realtek RTL8139/810x Family Fast Ethernet NIC
11 VIA USB Universal Host Controller
11 VIA USB Universal Host Controller
11 VIA PCI to USB Enhanced Host Controller
11 CMI8738/C3DX PCI Audio Device
11 VIA USB Universal Host Controller
11 VIA USB Universal Host Controller
14 Primary IDE Channel
15 Secondary IDE Channel
8 System CMOS/real time clock
13 Numeric data processor
6 Standard floppy disk controller
4 Communications Port (COM1)
3 Communications Port (COM2)
12 PS/2 Compatible Mouse
1 Standard 101/102-Key or Microsoft Natural PS/2 Keyboard
I have tried going into the BIOS to change the settings for anything related to IRQ's, but it seems no matter what I do, a new card is always assigned to IRQ 11. I read on one board that IRQ 11 is actually an IRQ that sets up 255 virtual IRQ's within it, so there should really be no conflicts between components sharing it, but there is definitely a problem between the cards and my system when I install them, particularly with graphics and sounds applications causing freeze ups.
Is there a fix for this situation? One friend of mine thought I might have to reinstall Windows, but I'm really hoping I don't have to do that. Is there a possibility I could do a repair instead? I'm running Windows2000 Professional with SP4 installed.
I'll give you my system specs:
AMD Athlon 2600+ XP CPU
Soyo DRAGON Ultra KT333 Mobo, Platinum edition:
Windows 2000 Professional w/SP4
1024 Mb PC2700 DDR Ram
ATI Radeon 9500 Pro Graphics card w/128 Mb Ram
Western Digital 250GB 7200 RPM ATA133 HDD
Western Digital 120GB 7200 RPM ATA133 HDD
Plextor 712A DVD Burner
TDK VeloCD CD Burner
I have the latest drivers installed; Catalyst drivers for the GPU, VIA 4 in 1 chipset drivers, DirectX9.0c, etc.
Anyone familiar with this kind of problem and who knows of a possible solution, please don't hesitate to suggest it to me. I'd really like to resolve this issue, and will of course provide any additional information needed to do so.
Thanks
Lane
