7950 Does not display POST

post #1 of 3
Thread Starter 
Hi everyone, my new Asus 7950 Direct CU II will not display either the POST screen or the Windows start up screen. When the desktop loads, it displays perfectly and runs games well, oveclocks like a beast etc but no POST.

All I get is a thin white line at the top of the screen until the desktop loads then all is normal.

PSU is a 1000w 80+ coolermaster silent pro that easily handles the high power draw of a 1.3V overclocked 5870.
MB is an Asus Crosshair IV formula
CPU - 1090T overclocked to 4.1 but have tried it with standard clocks.
All leads etc perfect, I have a 9600GT for hybrid Physx so luckily can use that to test everything else is fine and it is!

I will receive my third card today and fear that it will be exactly the same.

I have read that there are sometimes some issues with HDMI resolutions during the POST but with my set up the only option is to use HDMI for the digital sound (AV receiver)

Can anyone help me towards a solution.

Oddly enough, when I have both cards installed, even with the HDMI plugged into the 9600GT, the post does not display. As soon as the 7950 is removed it all works as normal so my 7950 is actually stopping the POST being displayed even when it has no outputs connected and is not being used to display anything!

Cheers guys, i'm at a loss, the card has the latest BIOS so does the MB.

One last thing, I read that sometimes on the newer cards, it tries to output a 360 or 480p resolution during post and some displays don't like this on HDMI the older cards apparently output 720p so no handshake issues. could this be altered in a bios editor for the card?

Use DVI port on the graphics, if you use HDMI or mini DisplayPort then you might have a blank screen during POST and Windows loading until graphics driver takes over.

CHEERS..

Hey, thanks for the reply but that's not an acceptable workaround. It would sort of be like buying an Audi R8 new but only being able to use First and second gear mad.gif

When i bought my 5870, it was the most powerful card in the world and worked perfectly, now I have one of the top cards out right now and having it not work with HDMI is crazy. It should be solid as a rock as it may even become legacy hardware with Ultra HD if HDMI 2.0 isn't a success.

I HAVE to output from HDMI as I have £2000 worth of speakers that need a digital and lossless source or I may as well get a £100 5.1 system in a box setup frown.gif

Would this be an issue with the Asus bios or across the entire HD 7xxx range?

I got a reply from Asus from a girl saying she is just leaving for a 4 day holiday...... thanks Asus lol
