Read about this on ATI's forum. You see the windows loading bar, then after that the screen goes black and the "no signal" pops up. The problem is DVI input with the 4800 series are effed up for Vista. From what I understand the drivers are defaulted to a super high resolution and high frequency, so if your monitor don't support it you get the blank screen.

You can go into safe mode and try to fix the issue, but I've been there and back and nothing has worked.

Right now I'm running Vista but I did not install the video drivers, nor did I let windows update get any drivers. I'm loading a screen every time.

There was a hotfix released by ATI that, when I installed, did not fix the problem. There is also some people saying that they load up the monitor with a VGA adapter, then switch to DVI. I'm not going to do that every time I load up the CPU.

I'm resigning to buying a new monitor that isn't affected by this ordeal and giving my monitor to my dad.

Unless someone here has a fix that FOR SURE works.

What monitor do you have?....I'm using Gigabyte 4870 card in DVI mode which works fine on my monitors with Vista x64(Belinea 102035W 20" 16:10 screen and Asus vw246h 24" 16:9 screen,using Windows default monitor driver).

No issues with any CAT drivers btw(full CCC package I use).

Btw you tried using DVI to HDMI cable or adaptor if your monitor supports HDMI.
Make sure your refresh is at 60Hz in Windows since blank screen normally happens if refresh rate is too high ie if you have a CRT set above 60Hz then plug in a LCD after,seen this happen a few times.You might need to borrow a different monitor so you can get pass the blank screen part and check 60Hz setting plus load drivers etc..Sometimes in rare cases its the monitor thats used with the video card that causes the problem or incompatibility.
