I have a acer aspire one d225e. I was talking to my girlfriend on my computer and everything froze so I turned it off. Now I turn it on and it keeps beeping and it comes to this black screen that says,
check cable connection!

no bootable device -- insert boot disk and press any key

Yikes - it's not finding your boot drive for one of any number of reasons. Take it to a reputable computer shop and if they can recover your data, buy an external hard drive and start backing it up regularly.
Every student unfortunately seems to learn this the hard way, for the most part, but maybe you'll be lucky and your drive won't be fried. Even though you'll have to shell out $ for an external, it's totally worth it to prevent having to rewrite a thesis or something like that.
Well, it honestly sounds like your hard drive might be dead. If you have a spare one or access to a SATA to USB cable, you can test it but if you drive is dead you'll need to replace it.
Alternately, you can try to force the computer to boot from the hard drive (sometimes the boot order gets messed up, although it happens more on desktops than laptops.) Right when you turn it on, there might be an option to press F12 or something like that to change the boot order. Try that and make it boot from the hard drive.
You can also try going into BIOS to see if maybe the drive isn't recognized. That will help shed some light at least - post back here what you find and we'll go from there.
