My M15x is suffering something horrible

Well to cut right to the chase my M15x seems like its ready to croak. I've had it since about mid-august and occasionally playing starcraft 2 or another game the screen would just go black and i'd have to do a hard reboot. However in the past few weeks its been either black screening or sort of a bluish white screen with vertical lines on it all the time. Whether gaming or even just watching YouTube videos in Chrome. I do have the latest bios and just a couple days ago reinstalled the newest ATI drivers. That seemed to stop the problems for a day or two but just now browsing on chrome with iTunes going the screen went that weird light blue with vertical lines. Its extremely frustrating to say the least and even somewhat embarrassing (watching youtube videos with a group of friends and its needs to be restarted twice ). So is this like anything all of you very computer savvy people have heard of or is my 5850 most likely defective? Thought i'd check here before Dell as I hate phoning them (can never understand what there saying). I've monitored my temps a couple times in the past and they seemed pretty normal from what I could tell. Nothing really high.



Thanks for any responses guys, Its very frustrating when your baby isn't running at full efficiency so hopefully someone can help me out. Anything I can try to avoid a tech ripping open my M15x is greatly appreciated.



Oh ya just thought I should mention this, also a couple weeks ago I installed Civ 5 as well as Fallout New Vegas. The installs went smooth but if memory serves I accidentally reinstalled Directx from Civ 5 when I already had the latest one installed. Not sure if that could be causing any issues as I did get the black/ blue screen randomly before that. Thanks!
