GA-990FXA-UD3 problems..
I was carefully when installed the processor and memory to an Corsair 1200i. It started up with nice temperatures together with a R9 290X card.

Went into bios to check some settings, closed all down. Now, I added a drive, and at powerup i smelled a light burning. Stopped fast.

Now, the board just starts up with blank screen (the R9 is alright..), the keyboard light lits up, but nothing more. THe led display says: 0d.

Not my day... Any clues?
I did. Eh..opps! Working fine, 3 * R9 290X. And I have a couple of older cards to play with, too..
