My 8.04 went amiss, so don't worry about it. The lack BIOS of options on your PC, I will put down to Dell customizing it. Fan/temp setting are aften found under Computer Health.
Will work just as well as the latest in the stores, >
A QUESTION/confirmation about sata cables:
fyi...was curious, so replaced rear case fan with the original hp case fan and computer booted up without<br style="color: rgb(13, 41, 117); font-size: 13px; line-height: 19px; background-color: rgb(242, 242, 242);">
This is only guesswork. Dell have used their specified fan with different pin out wiring or pin out on the MB socket. Can't see that it is the new fan as it runs.
AS the computer boots up to the Windows screen, (if you mean the Desktop?) I would leave that part of the hardware as is.
Have you looked at Connecting the front fan yet?
Test your sound.
AS you have done a restore to the OS, it will need to be updated via windows Update. Until this is done your system may not be secure for going to other sites.
You will then need some free Virus protection like Avast!, AVG.
