Had the same issue with an HP Envy using the (7690m) crashing on shader 4 before startup. Since HP's drivers are outdated and ATI drivers wont install (as HP are modified versions so hardware mismatch causes abort)
ATI recently did release the 12.2 pre certified drivers though, which solved my crashes at least.
Taking a break from Regnum due to work leaving me little free time! So my laptop must go for now! (ask me for full details, it is an Alienware Mx18 3rd gen Ivy bridge i73920xm & configured with SLI twin Nvidia 675m, paid 3,330$ asking 2,800$ or 2,400$ + netbook.
