Try the VGA port if you have one. If you're using a higher tech port for video, switch to that later. As well, if you're using an add-in card, disable any MB video device first.

I have written to ATI but, of course NEVER got any reply
This is ONLY a recent problem - I have had this computer for a couple years with this current configuration & have installed several Hard drives during that time for different reasons (size, OS (Windows, Linux) ETC) - but, with Microsoft ending support for XP - I decided to get an SSD drive, I wanted install a small partition of XP for programs I really love on XP (photo, etc) & a new version of LINUX for my main OS
However, as I have done times before on this computer with NO prior problems, what is happening now & at first for whatever reasons made me think it was with my motherboard (ASUS) to which I wrote to the company as the company for your motherboard also provides the BIOS for your system - But, ASUS is no help at all & responded with a half ***, pass the buck response - obviously they won't help their customers ------- but, then it hit me like a ton of bricks, who knows why it didn't before hand
What is happening, is now when I am trying to install a hard drive - during the installation of the OS (have tried both Windows & Linux - and this happens with both) - that my monitor switches off -of, course it's still got power but, as if it no longer is getting signal power, as if I put it in sleep or turned off the monitor ----- I haven't had this problem before & the computer works fine with no problems at all with my current hard drive - once with NO drive attached while adjusting BIOS settings - it did this
This isn't a compatibility issue with the new SSD as I had also tried using an older unused HDD drive reformatting with LINUX on there & this also occurred - NO new hardware (graphics, sound cards have been changed) - the computer is how it has been for a couple years BUT, only now is this problem occurring --- I did actually get Windows installed onto the new drive & have had it boot to the desktop - I have even started to set up once before my monitor turns off - even if this was because, it still hasn't updated all the drivers yet - it hasn't happened before with other drives used - I did try to plug my monitor to the onboard VGA port of the motherboard to get to finish setting up but, no signal at all there
I can get as far as the actual installation of the OS - & Windows did actually install but, still turns off & can only get so far with the LINUX install before it too also turns off ------- Because, I have an ASUS motherboard - the Bios sucks, very very limited settings - I am only impressed by the fact that it does in the least offer USB support --- but, again as far as the monitor & screen goes - this problem has NEVER happened before & does NOT happen at all with my current year old drive with WINDOWS XP - but, I will have to stop using it as XP is no longer supported I will eventually be unsafe & unsecured to viruses & such
