The Backstory: Today, my Realtek ALC883 chip stopped working on my motherboard. I tried reinstalling the drivers and such but nothing worked, so I did a full uninstall of the drivers, disabled the onboad, and turned off the pc. I grabbed my SB Live 5.1 and popped it in the PC. It booted up fine and I went into windows. I went into device manager to update the driver. I clicked update driver, it proceeded installing the WDM drivers for it. It seemed like everything installed fine. I started to reboot, and upon that I BSOD'd. I couldn't tell what it said too clearly, as it just flashed for 1 second before it rebooted. But I did see "IRQ" on the screen. I booted back into windows. Still, no sound. I went into device manager, it looked like the SB Live Drivers had been installed. I double clicked on them and they said that they were working properly. But still, no little sound icon in the system tray. I went into SOund and Audio Devices and could not select ANYTHING. Could not move any tabs or sliders, everything was greyed out except the cancel button. Whenever I tried to uninstall the drivers, I would BSOD again. Whenever I try to go to the "Resources" Tab in Device Manager on the sound card, it locks up. Whenever I try to disable the device, blue screen. What I have tried: Uninstalling it: BSOD Reinstalling Drivers: BSOD Changing the Resources: Lock-up INstalling the Creative Drivers: BSOD Removing the Card and Putting in another and installing their drivers still results in BSOD and the same results. All cards work perfect in other PCs. My Hypothesis: I have reason to believe that this is an IRQ conflict of some sort. It's currently assigned IRQ 21. The card has worked in other PC's so I believe there might be some sort of conflict between the chipset and this card. But it seems like once I install it and this happens, no other audio cards work and they suffer from the same exact problems. Please help. This is the third time this has happened and the only way I fixed it before were full reinstalls of windows.
