something is wrong with the hard drive, I'd try another one. Use your system recovery media to put Vista on it.
I have a HP computer that runs Vista 64 bit Service Pack 1 and has appeared to crash. It is a desktop Model S3500f. It had been kept up to date.
I tried to load the computer today and it gets stuck in the load screen (little progress bar) and then goes black or sometimes blue and stays there. I tried the diagnostics and it said the hard drive did not pass. It was the BIOHD 8 error. I cannot get it to go into any mode at all. It showed the start windows normally screen once and now won't do it. I tried F8 and it will not open a screen to choose safe mode. I cannot get into it at all, just the F10, F9, and ESC. I tried F11 and all it says is Windows is Loading Files and gets stuck again.
This computer is out of warranty. Any tips, tricks or help will be appreciated. I am not sure what to do.
