Windows 7 - Dell laptop suddenly running slow now Bad_System_config_Info

So I have a Dell Inspirion 1545; One day when I turned it on, it started running extremely slow. It took almost 30 minutes just to boot to password screen, I put in the password and almost took another 30 minutes to get to desktop. Well then it started giving me errors like Dell Dock has failed and Windows (Something) had crashed, I got it up long enough to run Malware Bytes, and CCleaner to fix registry errors but nothing. Now I try to turn it on in normal mode and takes about an hour and thirty minutes to get through everything and to the desktop and thats if the icons decide to show. and if I try to get it into safe mode I get Bad_System_config_Info bsod.

I dont really know whats going on, it decided that it was gonna shit out on a random day. The computer is out of warranty and Dell doesnt provide support for it anymore.

Its basically un-bootable. There are no system restore points aswell, Repair your computer says it fixes everything but it doesnt.

Has this happened to anyone else?

Nope but you could do a clean install if you have the win 7 dvd.

Is there a way to do this without losing all data

If you cant boot in any other way your options are limited.

Learn how to break down your laptop to get to its' h/d and remove it.

Go to a friends house and print out the service manual for your machine to get this info.

Purchase an adapter for it from Newegg to plug it into a regular pc. The adapter will change the interface from 1.75" to 2.25"(IDE) where you can attach a ribbon cable and a molex (normal 4-pin plug) power connection.

Open up your friend's pc and attach it to the middle connector on either ribbon cable. When you boot up, it will be recognized. Get your data off via burns to dvd's.

When you've captured your stuff, you now have to wipe this drive. Print out a tutorial from this forum to do this. One of the gurus on this site will post which one.

Re-install the "cleaned" drive back into your laptop and do a clean install of your OS. You will need to know your key. Do you? If you have no idea, you will have to cull it from your OS now with a utility to do that.

Yeah, I know how to do all this. I was just wondering if there was a work-around. I was hoping it wouldnt have to come to this.
