Need help! display issues with brand new laptop.

ok ffs now I'm annoyed... just ran L4D and while it is better when I run it at the native resolution it does the same flickering ****. This is not what is supposed to happen on a premium alienware laptop.please can someone help me this is really frustrating

Sounds like either a driver issue or the GPUs are bad or overheating. Can you find the temps on those cards? Update your drivers, too.

you have a bad video card

oh and because for no apparent reason I cant edit my last post I will have to do a new one.

it cannot be drivers because I have reinstalled new ones repeatedly and no one else on earth appears to be having the same problem as me, as usual. I reinstalled the OS and it worked, then in the middle of playing somthing it happend again, no reason for this either it just happend. Can anyone help please.

Update:
ok yes I think there is one faulty card, every time I reinstall the drivers it automaticly disables one card for some reason; and an error message pops up saying how the card is incompatible with the driver. So I think it is effectively only running one of the cards, and everything runs fine like this without issue.

Then when I restart/shutdown it automaticy enables the other card, thats when problems occur, so, one faulty card I think. And thanks for everyones help.
