Hi HyperViper,
I've posted on this poblem a number of times as an owner of an early 2010 MBP.
I had a whole range of problems when I first installed Mavericks including the graphics corruption, stalls, crashes, turn-offs, general slow performance.
I first tried a reinstall to no effect. I then tried a reinstall having done an erase of the hard drive, no effect.
I then did a reinstall having first underaken a zero overwrite of my hard drive and bingo, no problems of any kind since, even prior to installing 10.9.2.
If you decide to try this route PLEASE DO A FULL BACK UP TO AN EXTERNAL DRIVE OTHER THAN TIME MACHINE, as a time Machine reinstall is not always successful.
I'm convinced that the problems are somehow related to a conflict with an earlier operating system and only doing a zero overwite which completely erases the hard drive as opposed to an erase which removes the disc directory only cures the problems.
