However, not sure how it works with mobiles. Does the 5870M use system memory kinda of a hypermemory/turbocache dealio?
That might be worth looking into. IE, its not failing because of weak VRMs, or 3D clock mode, but from an increase is necessary memory caching.
Worth looking into at least.
(Was looking into this for a LLano setup I built for a buddy is why I thought of it mem changes resulted in no video, turns out its just a failure of Asrock).
Actually they come with two drives retail so it had a drive in it when he bought it - just one drive though. He already answered that question, though.
The 5870M in these models use dedicated GDDR5, but some laptops with 5870M use shared resources. Not in these though...\
To OP: Try a CLEAN full install of win7 64 bit. Install drivers, but NOT the asus crap you don't need. Make absolute sure you have the latest drivers from the internet. Make sure you're not overclocking at all. You say all the temps are nominal? The ram and such are not getting too hot? If all this fails, I would definitely take it out and try and reseat/reapply TIM - but ONLY if it's out of warranty, they won't RMA, and the lady won't take it back.
Honestly though if she sold it to you broken, you should be breaking down her door to murder her.
