Laptops are bulletproof, (meaning so the owner cannot screw it up!), they are not designed to be overclocked and have no BIOS features that allow it.
If gaming fps was important, you should have bought a much higher end laptop with upgradeable GPU capability, rather than that Dell Inspiron 17r SE, Walmart Special.
Unfortunately, the end result is, you get what you pay for, especially when it comes to laptops.
Another lesson learned the hard way.
