Window 7 RC and used, and monitor and even change the graphics card and tried on another computer, everything is fine. Apart and also used other graphics on the same motherboard to see if the problem was that.

In the video you can see the problem on the desktop, when you make these "Artifacks" very rare, are not for the camera, set well.

E usado window 7 RC, e cambiado de monitor y incluso e probado la tarjeta grafica en otro ordenador, todo eso esta bien. Aparte tambien e usado otra grafica en la misma placa base para ver si era eso el problema.

En el video el problema se puede ver en el escritorio, cuando hace esos "Artifacks" tan raros, no son por la camara, fijaros bien.

Could you be having a heat problem? Verify that all the fans are working.

Open up the side of the case, and direct a house fan at the innards. If that fixes the problem, you have a case cooling problem.

check your graphics card fan isnt clogged up with dust and grime.

The fan is fine, I can assure you that is totally clean inside.

Temperatures

Is that at idle, or under load?
If it is at idle, the cpu temperatures seem very high. That is often caused by not mounting the cpu cooler well.

The gpu numbers are ok, assuming that they are correct.

Another cause of strange problems is a bad or poorly performing psu. What make and wattage is your psu? In particular, what is the amperage on the 12v rails?
