Could be a few things...
1. IRQ conflict if using PCI/PCI-E, or could dislike running in a too fast PCI-E slot
Solution, change to MSI IRQs for the device, and/or set bios to 1x for PCI-E port card is using.
2. Make sure full mux reception is off.
3. Check cabling
4. Driver issue
5. Plug in power connector to card if appropriate.
....Likely bad cabling, or interference, none of the above will always give/not give bad signal quality/SNR
As a note though, low "signal quality" means that the electrical signal being received from the dish/aerial is weak, this isn't strictly related to bad reception, you can have a strong signal quality and still crap reception due to low SNR. This would point to bad cabling or power not plugged into card, likely the first as most cards are fine without their power cable plugged in.
Sorry for the vague info and if you already aware of all this.
