Hackintosh freezes in few second or minutes (OS X 10.9 on Dell Optiplex 780)

[BatteryNone]

Hello,
I've installed Mac OS X on old Optiplex 780 and everything worked fine. It worked great, I could use everything with no problem. However I tried messing with configuration and it didn't even boot. It wasn't worth trying to edit those config files from another PC, so I went and reinstalled the whole OS. Oh boy, that was a huge mistake. No matter what I tried, how many times did I try changing BIOS settings, swapping and removing RAM sticks, reinstalling again and again... Installed it never worked more than 2 minutes. Interestingly, installation from USB went fine, so if that installation OS has same kernel as installed OS, it probably can't be the cause of my problem.

Have you got any ideas, why, after reinstalling, it stopped working? I've found same problem on Apple forums, where it was happening to a real Mac and solution was easy - replacing the HDD, because the old one had gone silently bad, although it was still doing it's job somehow. I consider this very well as a possible cause of my problem, because HDD in my Hackintosh is from January 2008...

Thank you for all replies!

Well, I was trying to force resolution as drivers weren't working at that moment. I don't know what went wrong.

Sadly no, I didn't have a backup. I was planning to make one after reinstallation so this doesn't happen again, but as I wrote, reinstallation wasn't successful.
