My DN2800MT board is set up with mSATA OCZ NOCI 60gb + 1 off 4GB Kingston SoDIM, its running Windows 7 Ultimate with the latest BIOS from September flashed.
The PC runs fine and does all as expected until i plug my TBS6981 DVB S2 Tuner card in, once plugged in and powered on the board does nothing other than illuminate the power light, the VGA doesnt bring the monitor out of standby and i don't get any POST indication or beeps (not sure if there is an onboard beeper). All i can do is just power it off again.
I have tried almost every setting in the BIOS and i get the same effect
From what i can see the card is PCIe 1 compliant using a boot, n2800mt

Latest drivers etc installed, although this doesnt sound like its a driver issue
Ben64, we try to make our products compatible to many third party components as possible, but we cannot always guarantee compatibility. Unfortunately in this instance this would appear to be the case.
Have you tried another PCI device on your motherboard, like a video card, in order to check if you got the same behavior?
It does seem to be a common issue with some motherboards, but it does appear to be the motherboards issues rather than the card. it seems to suggest it will work as long as the PCI-e spec has been followed correctly
