GTX295 crashes

Hey guys , 

                   I was just playing modern warfare 2  and my aurora crashed and restarted then it wouldnt reboot and was making  6 beeps i checked my owner's manual and this says 6 beeps means  video card or chip failure.........  After waiting 5 minutes i tried to boot again and it seems to be working now but i haven't tried games yet. As I've previously stated i was getting a hell of a lot of crashes a couple of months ago but turning off alienware fusion services seems to have fix that but i have had a few random crashes over the last month probably 3 or 4.  This is the first time I've heard the 6 beeps  but now im wondering if my graphics card is whats been causing the crashes since i fixed the fusion issues .......  I'm basically wondering do u guys think i should ask for a replacement graphics card.....    I don't think 4 months after buying my Aurora i should be having these problems also how would i go about requesting a replacement ?  

The fact i heard the 6 beeps has me worried that my gfx card might fail completely real soon
