Laptop: Dell XPS L501X
OS: Windows 7 Ultimate
Processor: Intel i7

I was reading through the system logs on my Dell XPS Laptop running Windows 7 Ultimate, and noticed the error: Processor ____ is being limited by system firmware. After some research, I determined that this was a result of Intel Speedstep and, being the dummy I am, decided to disable Speedstep from the BIOS in order to stop the error (not yet realizing it was only doing this in order to save power when not in use). After doing so, the computer took a ridiculous amount of time to boot (around 7 minutes) and continued running much slower than usual. I restarted, enable Speedstep again, and found that Windows would not boot at all. I then ran the Startup Recovery program, and the only thing it said was that the System Files were possibly corrupted. I then ran a system restore, with the computer still running slow, and then another restore to an even earlier date. Now I get to the Windows logo animation and then get a BSOD saying Unmountable_Boot_Volume and Stop: 0x000000ED.

So, now I've gone from laptop that was working fine, to something that won't boot in a matter of a couple hours.

First of all, was it in fact disabling speed step that caused this? Or could this have been from a virus somehow? Seems too coincidental to me.

Secondly, I am worried that since this is running an i7 processor, that the reason it was so slow was that the processors were overheating after I disable Intel Speedstep. Possible?

Thirdly, is this fixable, or am I better off saving what I can off the hard drive and reinstalling?

Let me know if you need anymore information. And thanks in advance.

UPDATE:

I've created a Recovery Disk using a separate Windows 7 machine and can boot into it on the laptop, but after I select my language, it spins indefinitely at the screen asking me to select my operating system.
