It greeted it me on start-up with the usual black screen but decided to stay that way, all day.

First thought was the monitor had carked it, but the other monitor didn't want to play either.

A look inside the case was disturbing with all the dust and crud in there but quickly showed that the fan on the VC wasn't spinning.

I unplugged the power lead, blew some dust off the card and plugged it in again. Nothing, nada, zip!

So I'm guessing that it is either a faulty power supply (it's a Seasonic and it wasn't cheap) or the Video Card has given up the ghost. All the other fans are merrily spinning away which sort of convinces me that it's the VC.

Am I overlooking anything before I order a new card?

And AK, how is your new(ish) card going. I cant remember what you got but at the time your reasoning sounded good. I'm thinking something like a Gigabyte Radeon RX 560 Gaming OC 2GB 128-bit GDDR5 on board memory.
