Asus Crosshair V Formula-Z - Error 99

j666gak · 15 Sep 2014 at 21:20

For the past 18 months I have had no issues. I recently decided to change my case and moved everything over to the new case, and now it won't even POST or display anything on a screen. The only item I have added to the system is a Corsair sealed water cooled unit.

I was then advised to clear the BIOS, however this got me no further. I get Q-Code 99 which means "Super IO Initialization". I have check all power and SATA cable are seated correctly.

I am at a loss as to what to try next, can anybody help?

Thanks

Have you checked ACHI is enabled if you have an SSD?

I can't check it without getting in to BIOS, and I can't get anything on a screen or hear POST.

Make sure you don't have any short circuits anywhere - motherboard standoffs installed correctly, no loose power cables touching anything they shouldn't.

If the rear I/O plate has those metal tabs on make sure they're not shorting on anything.

Make sure all the power cables that should be connected are - 24 pin & 8 pin to the motherboard, any 6 pin/8 pin cables required by the graphics card.

On Intel motherboards an overtightened CPU cooler can cause problems. I don't know if AMD is the same but it might be worth loosening the cooler a touch to see what happens.
