Repair reinstall Windows 7 without using autoplay or explore.exe

[swimmeroc]

So the explorer.exe on this computer crashes all the time. I am unable to open folders of any kinds. I can however open chrome and certain other program. Some of them crash the first time but open the second. I want to reinstall Windows 7. I can log on in normal mode, its slow but it does do it. However, inserting my usb flash drive with the windows 7 install files on it won't open. The autoplay feature never opens. Guess it requires explorer.exe The start button works and sometimes I can open command prompt but its random. ctrl+alt+del does not open task manager. Usually just freezes the computer. I really just want to reinstall windows so that I don't have to wipe the hard drive. As I am unable to open folders I do not know how to back up files on my desktop that I forgot to back up and are essential. Any ideas would be greatly appreciated.

My only idea that I had thought of so far was using an .iso file and a mounter. I can install the mounter and put it on the desktop where I can open it but then I don't know how to get to the .iso file I have saved. If I can reach it, would this work to start the process of the repair or is that not possible. I know its two different things I am asking.

And right clicking anything causes everything to crash as well

Hi
to get your files you want you could run a live cd like ubuntu and save them to a flash drive. on some toshiba laptops you hold down the 0 key while you turn power on will get you to the recovery option to restore it back to how it came out of the box.

I'll try the ubuntu. The 0 key thing won't work because I did a clean install of windows 7 and wiped that feature to oblivion.

then you will need a disk or a flash drive with the win 7 iso. can follow this guide http://www.sevenforums.com/tutorials/2432-usb-windows-7-installation-key-drive-create.html
