on Elite series of HP Pavilion desktop PCs. I saw an article on an ex lawyer who got over $800 dollars in small claims court over the same thing. Class actions only make money for rich lawyers. Probably didn't even punish HP enough!
I've torn my hair out for three years with mine; and if but only for the fact I am a technician, I would never have come to the bottom of the problem with this series of junk PCs! It is now a pretty good computer after about six or seven .NET updates over the years.
Don't dare use HP drivers for x64 systems - only Microsoft codes them correctly. I replaced all of mine with Windows drivers and am finally getting a functional PC. This is the exact opposite of the past with most XP designed computers. I include XP 64 bit (based on 2003 Server kernel) in that statement.
