ATI Radeon HD 3650

The original issue was that at 1920x1080 59 Hz the text (and mouse pointer) was blurry in some places, not all the screen. I've solved this before by changing the refresh frequency on other systems and monitors. But here, no way...
So, CRU brougth me back to life, and I couldn't believe my luck when I saw every letter perfectly defined. But happines won't last forever. After reboot, the image got blurry again.
Anyway, I've been trying several frequencies, over 59Hz (the monitor recognizes 59, 60, and 61 Hz as 60Hz.) at 1920x1080 res., and it works perfectly, but when I reboot, or power off, the image becomes blurry again. If I run restart64.exe, everything looks perfect again.

If you have to run restart64.exe after rebooting, that usually indicates a driver bug. The only way around that would be to flash the monitor's EDID. That would fix it once and for all.

I'm more concerned about why 59 Hz is blurry. You didn't show me what you did to fix it. 1920x1080 @ 60 Hz should already be defined as exactly 60 Hz with a pixel clock of 148.50 MHz, so I don't know what you changed. Normally the driver adds 59 Hz as an alias for 59.94 or 60 Hz, so that shouldn't make a difference. Are you using DVI? HDMI? VGA?

Make sure 1920x1080 @ 60 Hz is only defined once. It should be a detailed resolution and not a standard resolution. If the monitor has a default extension block, change it to a custom extension block to make sure it's not defined in there as well.
