Pre-amp turntable hum

[Unley Legend]

Cheers, got myself one of those turntables with a pre-amp, the theory being you plug it straight in the back of the computer and record all of your old vinyl and put it on CD. Problem is, I get a hum when I "record." I tried it hooked up to a mate's computer and no problems. He has a sound card and mine is "on board". Is that the problem, or is it more likely circuitry in my house? Sounds wierd I know. I've tried running the turntable from a power point on the other side of the house, but no joy. Has anybody else experienced this? Thanx

Sounds like a grounding problem.

Tried grounding it to the PC case, made no difference. Is there another way?

only a guess but the fan of the pc could be causing the hum had this problem when burning cds on my old pc

Do you get the humm from your HiFi as well?

There is a way to do it... Althought I wouldn't recommend this if you weren't an ace at electronics, as it involes removing stuff.

You really should ask someone like an electritian or ask some Hifi store.

It could also be your PC's power supply, poor quality power supplies do this when running at full capacity.

Took it, the turntable, to a mate's place and it worked like a charm. The difference, we figure, is he had a sound card, and mine is "on board". Sound fair?
No hum when hooked up to a hifi, but you turn the pre-amp off when you hook it up to a hifi.
