VIsta Business and 7.4

[mix_master_adam]

Ok, so heres the story: get a brand new quad core with 4gb from dell, starts up fine, install 6.1 then 6.4, then 6.7, then 6.9, then it wont let me install 7.3 because of no installed 7, so I dump it all, buy 7.4, intall, all is good, but still have not opened a session, before installing all the PT though I installed to hard drives, an Acom Data 80GB USB/Firewire and a WD 500GB USB, restart after 7.4, then blue screen says system fail or something, it fades so fast before I can read it, keeps in this loophole of blue screen then restart for 15 minutes, stick in recovery dvd, restore to before any PT or hard drive, here I am with no PT and wondering if I install the 7.4 will it crash again? any ideas or things to throw at the new machine? Thanks...
