hey y'all 

im having trouble trying to boot my gateway FX laptop...it has been working for a good 2 years but now its not booting....it all started when i was playing Rfactor and it froze up on me. and ctrl alt del didnt even respond so i turned off the laptop with the power button...now it keeps trying to boot...it makes it all the way to the black screen load bar right before the vista logo comes up but then it goes into the transition black screen and stays then it restarts going to the windows repair thing. it runs though it and sometimes it attemps to repair it and then restarts and then the same thing happens...i dont think its a hard drive problem because i was able to get into the cmd prompt and i can see the files...i also totaly restored windows to factory default using the repair tool and still it does it...im starting to think it might be my video card because right when i turn it on and the gateway logo is on there is a couple really thin purple lines through it....if anyone can help me try to solve this prob it would be very helpfull...is it possible that the videocards heat paste is bad and could be affecting it in this way?
