Basically, I went out today and bought some nice 2.1 speakers, and I thought to myself 'why not get a new soundcard'. MY old one was a Realtek AC97 one, which I know has had a lot of problems. I bought a PC Line 5.1 Channel Sound Card (model: PCL-SC5100). Went home, fitted it into a spare PCI slot. I didn't connect any wires for CD/DVD audio. I couldn't take out my old sound card because it was factory built, so it was onboard. I put it back together, and installed the drivers. After installing the drivers from the CD, it worked, much yayness. I restarted the computer as the setup asked me to, and when I did my computer didn't load up the logon screen. It just stayed black. Yikes. I loaded it in Safe Mode, uninstalled those drivers and restarted. It worked, but no sound was coming out. I put a song on, and I had this message come up (using Winamp ) Bad Directsound driver. Please install proper drivers or select another device in configuration. Error Code:8878000A Yikes... Well, this is my problem. Since, I've reinstalled and uninstalled the old drivers twice and it didn't work. Seeing as I had the other sound card still in, I tried installing the old drivers for the AC97, and it still doesn't work. I'm having a lot of trouble with this, please give us a hand guys. Thanks muchly. =D EDIT: My specs, incase its too much trouble to go back and forth to my profile. Intel P4 2.6GHz 512 DDR RAM 80GB HDD ATi Radeon 9200SE Old sound card: Realtek AC97 New sound card: PC Line 5.2 Channel Sound Card (model: PCL-SC5100) And I've tried loading Everest/AIDA32 to try and find out the make and model of my motherboard, but under the Motherboard Name field it just reads Unknown. I dunno if I have a crappy Mobo, or if I'm looking in the wrong place. Thanks again guys.
