I am having the exact same problem with a similar setup computer (Dimension E521, AMD64 dual, 2GB RAM, 250 GB HDD with plenty of space, Radeon X1300 with 256 MB and Dell standard 20" monitor, Vista Home Premium SP2) and I am in the process of going through the same list of things to try... checking cables, reboot (several times), safe mode, updating drivers, BIOS... alas nothing has worked.
The most curious thing, as you have found, is that the system will not detect the Radeon X1300 from a 'cold' boot but after three or four reboots using the onboard graphics card (nVidia 6150LE with 64 MB) and VGA cable, once the system had 'warmed up' it will detect the Radeon on the DVI cable - it will continue to work on reboots and shutdown/restart until the case 'cools down', for example, the next day when im back to the same old problem.
If anyone knows what is causing this - and how I can fix it - your advice will be greatly appreciated.
Cheers, Damon

When I decided to re-try the monitor, I unplugged my ViewSonic LCD and plugged in the LCD off one of my old computers. When I had tried this a couple of weeks before, I had gotten a driver error. This time, the screen came up immediately and worked every time I booted up. Next step, take the monitor from my main machine and plug it in to the old WinXP computer. I got the same error on the old computer with the new monitor that I have been getting with my primary computer. One more try. I unplugged the digital monitor cable and plugged in an analog cable on the old machine. Same error. I went out an bought a new Samsung 23" LCD and it has worked beautifully ever since.
I can't believe that I didn't re-try the monitor sooner. It was easy to believe the monitor was functional. It worked beautifully when I was able to get it running and when I couldn't , I either got nothing or a message showing no feed trom the graphics card. Other posts have reported black screens from Radeon graphics cards, so It had to be inside the CPU box....

Hi Mike,
