Computer Recording - Hum related to LCD monitor

Hey all,

I'm having an annoying hum problem with my computer recording setup. I notice it goes away when i turn off my monitor. Weird.

I moved the PCI card away from my video card, but no dice. Weird.

Any suggestions?

My setup:
Box: Dell Dimension 8300 - 2.6 Gighz
Video Card: Nvidia GeForce FX 5200
Monitor: SyncMaster 941bw
Audio Card: SoundBlaster Live!

Audio output run through a mini-to-RCA cable to an Alesis RA150 connected a pair of Tannoy passive speakers.

    it may well be the Soundblaster - I am doing everything internally and only using the SBL to monitor because that was the only card I had when I lost my interface - it has a weird ass hum a lot of the time.

        I agree.

        I absolutely will not use the SBL for anything other than playback. it's really frustrating because I am building a rather nice Jazz/Funk/Soul collection on wax that I reaaaaaaaaaally wanna sample... and put scratches over tracks, etc... got some stuff with the Last Poets I wanna sample SO bad but I won't, because I hate the sound quality.

        I think the E4 was a great unit and I miss mine, even tho I can do it all in software now. but perhaps Emu's last great unit?

    Thanks for the suggestions!

    I feel embarrassed to say this, since it's the audio engineer version of "did you remember to turn it on?" But as soon as i put the monitor on another circuit, the hum went away.

    Thanks again,

    bi

      hehehe

      I think we all do that from time to time.

      (upgrade your interface when you get a chance. I am brizzoke but I'm going for RME or Lucents when I actually have some dough - don't like the Apogee's much. also, try running everything mono you record thru an Avalon U5 - not that expensive but DAMN! I was recording a Minimoog and I was like, "hmm, this ain't all that" and then ran it thru the Avalon DI and suddenly went "HO SHIT!")
