If you visit the forum often you learn that these do require maintenance such as a good cleaning of the vents, heatsinks and maybe a check by a technician that the heatsink(s) haven't lifted off the chips. The artifacts are common signs of overheating and will lead to an early demise of the unit if the yearly maintenance is not being done.

My HP Pavilion zd8000 has started to accumulate white, whispy screen artificats, that also appear to be increasing in opaqueness and number very quickly. Has anyone else had this problem? Or know of a way to remove them sans a major repair job? Thanks.
