Tyan Tiger S2460 EMI problems- very difficult one

[tab62]

I am having EMI problems with this board. So far I?ve replaced the power supply, video card and monitor but no luck yet. My monitor and TV in the family are getting some serious noise on them when I turn my computer one.

Here is a list of my components:

Tyan Tiger Athlon MP S2460
Global Copper Heat Sink/Fans
Crucial ECC memory
Athlon MP 1900 Dual
Geforce 3 Ti 200 64 DDR
In-Win Q500 300 watt Case
Dell P1110 Trinitron Monitor
Western Digital IDE Drives
Iwill PCI ATA 100 Controller card

Any ideas on what might be wrong?

Thanks

Tom

how do you know it's EMI probs? It could be something else.
Try to enable spread spectrum option inside bios if your mobo has it. That option supposed to neutralize EMI probs but sacrifice a bit of stability.

Get some aluminum foil and put it in the case. It will shield EMI if you do it thoroughly. No, this is not a joke. Mind the heat though.
