Windows 7 "repair your computer" after BSOD is not doing anything

I have an old Dell Latitude E6400 lying around, (80 G HDD, 2 G RAM, I think, Win 7 pro 32 bit) and I was trying to see if I could bring it back to life, so I powered it on and it stated running system diagnostics. Everything was fine with that. Then I tried to boot it but I didn't get past the logo, instead I got the BSOD and a warning about something being wrong with my hard drive. It said try restarting it, and I did but the same thing happened. It said "run CHKDSK /F" but since I can't get into the OS, I can't do that. Then I went into the BIOS to see if I could do anything like run CHKDSK /F or wipe the hard drive, but no. I tried to find a way to bypass the BSOD, and there was something about using safe mode with command prompt, but I still got the BSOD. After searching online a little more, I found this saying to press F8 and select "Repair your computer" so I did that, and It's been 2 hours and nothing has happened. I have a cursor that I can move around, and the welcome screen with nothing on it (see picture below, but imagine it's completely blank otherwise). I read on some other posts and other support forums that this can take a while, but here's the thing: I don't have an installation disk or flash drive or a system repair disk or flash drive. Basically all of the other posts involve an installation/repair disk/drive.
Is this computer gone forever, or is there some solution? Do I just need to wait? I don't have any important files on it, so it's not high stakes, I just figured that it would be better than junking the whole thing.
If I ran a permanent magnet over it, would that wipe the hard drive and allow me to restart, or corrupt it beyond all future use?

Using a second computer, you may have to Frankenstein a few DVDs and USB flash drives with a few well-known boots and fixit utilities. Right now, I can't discern whether it's hardware or software or a little of both. Windows Repair (All in One) maybe can help with the software side.

This reinstall media for the 6420 which should do https://downloads.dell.com/Restrict...1CMP&uid=c07a39bc-ee68-4aba-b91b-3e53726a2011

OP, follow SIW2's advice, and of course the advice of others, they will not steer you wrong!

Do you have a Win 7 or 10 installation disk?

With a Win installation disk you can boot from it and on the install screen press Shift+F10 to launch a CMD window.
Type:
diskpart
list volume (take note of the HDD letter assigned to windows partition as it may not be C
exit (to exit diskpart)
chkdsk x: /f (replace x with the letter assigned to windows partition found above)

Pay attention on the results, specially bad blocks, bad clusters, bad sectors etc (indication of a failing drive)
