Hi guys, hope someone can help.

First problem I have got is that when my screen turns off for power saving, it will not turn back on, no matter what keys I press or how much I move the mouse. The only way I can get the screen to come back on is by putting the computer to sleep/hibernate and then resume windows - can be annoying.
Second, when I resume from sleep, my computers clock speed is pegged at 600Mhz - only a restart cures this.
Finally, when I change the power settings so that my screen does not turn off so soon, they work for the time the computer is on, but reset themselves after a restart.

Any ideas as to whats wrong with my computer?

Its an Alienware Sentia (model 233ii0) if that helps

TIA
