Getting BSOD, can't logon

I have a windows 7 home premium 64-bit Acer Aspire 5253 laptop
I'm having some serious issues with it, Im guessing regarding the hard drive,
When I turn on the computer, I get the black screen, with a few options, Safe mode, safe mode with networking, safe mode with command prompt, last known good configuration, and start windows normally, Any one of them I try, the computer loads, it gets to the Starting Windows screen, and then for literally about a quarter of a second you see the blue screen, and it restarts to the same black screen, this happens with ALL the options available at the black screen, I can't get to the logon screen at all, I have given it to repair shops, they all say, they need to install a new hard drive but they are not sure if they will be able to save the files, I really need to save a few VERY important files, I need them, and I didn't have any backups, can anyone help me with this?
Or give me a link to where this issue would be better handled?
I have the laptop with me right now, any help would be HIGHLY appreciated!
Thanks

Thanks for the link, just a couple questions before I try it
1) I am going to download Ubuntu on a 32bit laptop, but the laptop I need it for is 64bit, which version should I download?
2) It says Ubuntu Desktop download, would that work for my laptop as well?
3) I only have plain DVD's, no plain CD's, would that work? I also have a 16GB USB Flash Drive as an alternative

Thanks for all the help

Thanks, it worked, I got a chance to see and save the files I wanted to save, guess it just needs a new hard drive now

I didn't install it, I just tried it off the DVD, if there isn't an issue with the hard drive, then how do I get past the blue screen, to get to the logon screen?

Nope, none of the modes work, they all go straight to the blue screen after the starting windows logo comes up, the blue screen shows for less than a second, and then it restarts
