hi, i'm in desperate need of some help here. i installed a pci soundcard today. after it gave me tons of problems (windows applications were telling me that the audio device was always in use, or there wasn't one installed), i uninstalled it. however, before this, in trying to fix the no sound issue, i came across an article that told me plug and play was the problem, so i changed my machine.inf file and re-installed plug and play with the new one, but this resulted in tons of stuff going wrong. now, i've got about 5 different plug and play devices listed in the device manager, and none of them give me the option to uninstall when i right click on them. i can only really run my pc in safe mode, as all applications freeze as a result of what i'm guessing is all these pnp devices. please, someone help!
