Z60m FAILURES/ LENOVO IS KILLING ME!! HELP HELP!

[mattscool135]

now look...i have posted once before...but i need more help...my Z60m has a wierd problem. When ever i try to move it...the screen will phase in and out, pixelate, or give me a series of mysterious colors then go black, and the computer will shut down. I also get the problem if i put my hand down to hard on the left palm rest, or if i just nudge the pc on the left SIDE!

this pc has been a problem since the begging. it is one year old... and i have had to replace:

the key board
1gb of the 2b of ram i have (the ram broke somehow)
the system board
and the HDD
NOW MIND U THIS IS A DESKTOP REPLACEMENT FOR ME I DONT MOVE IT EXCEPT FROM MAYBE MY DESK TO MY TABLE OR TO MY BED!

I HAVE SENT IT BACK TO LENOVO EXCATCLY 4 TIMES! THEY REPLACE THE SYTEM BOARD, MOBO, HDD, BUT THEY NEVER TOUCH THE GPU....WHICH I THINK IS THE PROBLEM..THEY HAVE EVEN LOOKED AT AND RESEATED THE CPU! I NEED HELP...IS IT TIME I CALL THEM BACK AND DEMAND THEM A NEW PC...AND NOW THEY DISCONTINUED THE Z SERIES IN THE US. WHAT WILL THEY DO...THEY OBVIOUSLY CANT SEEM TO FIX IT.....PLEASE NO JOKE..SOME ONE HELP ME, AND ACTUALLY GIVE ME HELPFUL ADVICE, UNLIKE WHATI GOT LAST TIME! DOES ANYONE ELSE HAVE THIS PROBLEM
