I have a m17x with q9000, 260m sli and i have been having some problems, only owned less than a month, first

screen freeze, no mouse, have to hard reset, run diagnostiics and everything is ok, (2 times) black screen, have to hard reset

run diagnostics and everything is ok(2 times).  third, today i got a multi colred screen freeze same as before, ran diagnostics everything is

ok(twice today)   I have updated per dell driver site and still does it, (updated the first time it happened). does it in sli and normal modes

anyone have any ideas.  any help before i call dell support would be helpfull, i really hate to spend hours on the phone if

i do not have to.
