Hello Bojan -
I have not heard of this particular issue, so let's go over the basics.
Be sure you have the latest BIOS update for your board. Since you've had this system for a while, it is likely using the latest graphics driver. However, you should verify your system is using the Intel® Graphics Media Accelerator Driver version 220.127.116.1126.
Are you using VGA or S-Video for your monitor/TV? Have you verified this is not a monitor issue by using a different monitor for troubleshooting?
The additional information may help us troubleshoot the issue.

Dear Mr. Casey H.
I read your message and in the meantime I think I know what cause the problem, there was nothig wrong with drivers or monitor connections, it looks that the problem lies in the Compact 2 Port KVM Switch + Audio (PS/2) from Sweex. All this time I had two computers conected troughout KVM Switch having no idea that the Vga cabels have in the second line one pin less than the standard monitor Vga cable, on my Asus S-presso berbone (the first computer) I had no such problems, probably because its Pentium 4 3.06GHz (478 motherboard), but the second computer with Intel D945GCLF2 motherboard got disturbances wel, even when I would click two times on the intel graphic icon in the tray I would get stripes over the screen, some icompatibility perheaps. I hope that the problem is resolved now.I would like to thank you for your quick reaction on my question and for your time, that's what I call good service!
P.S. Sorry for my bad english, I don't use it much.
