My Alienware computer died. When I turn it on, it doesn't boot up the OS, it doesn't beep, it does nothing except run. No bios either. And then strangely, I can't shut it off unless I unplug the power cord.

Sound like the power supply to folks?
 
What happen to cause this? Was it all of sudden or were you tweaking around?
Call Alienware too might have a warranty
 
No tweaking. Just a sudden occurrence. It's a 6 year old Alienware rig, so it's out of warrenty.
 
Get a new psu and hook it up, if it doesnt work return the psu and start planning a new system.
 
Do you have (or know anyone with) a known working comparable computer that could be used to check components one at a time?

You could also go the other way and try someone else's PSU in your box to see if it works.
 
"It does nothing except run"

What runs? The PSU fan? The HDD's? The on-board fans? The HSF fan? The video card fan? Case fans?

Is there an indicator light on the motherboard that determines whether or not it's receiving power? Do you have a multimeter to test the PSU?
