Have you tried inserting your Vista installation DVD and running Startup Repair, as detailed on this page:
How to automatically repair Windows Vista using Startup Repair

What is Startup Repair?  This Microsoft page has a great deal more information about that:
Windows Help and How-To:  Startup Repair: frequently asked questions

Startup Repair is designed to detect operating system startup problems and troubleshoot any found and correct them with little user interaction.  It can repair problems such as:

- missing or corrupt drivers
- missing or corrupt system files
- missing or corrupt boot configuration settings
- corrupt registry settings
- corrupt disk metadata (master boot record, partition table, or boot sector.)

When the Startup Repair Tool has taken control, it analyzes startup log files for clues about the source of the problem and launches diagnostic tests to determine the cause. If it determines the cause of the failure, it attempts to fix the problem automatically. After successfully repairing the problem, it will reboot the system, and notify the user of the repairs, filing a detailed report in the Windows Vista event log.

If the Startup Repair Tool can identify the cause of the problem, but can't repair the problem by itself, it will provide access to a set of tools that you can use to manually troubleshoot the problem further.  One of these is the Bootrec tool described below.

If the Startup Repair Tool cannot identify or repair the problem, it will roll back the system to the last configuration that was known to work (Last Known Good Configuration.) Again it will add detailed information about the problem to the Windows Vista event log.

yes i have, and when i select repair, on the screen where it asks me to select the OS to repair i see nothing on the list.  I know i have the option to install drivers and what not for my HDD but i'm not running RAID or anything, just a normal hard SATA drive attached to the mother board.  I hit repair without selecting an OS (cause there isn't one to select)  and it runs for about 10 min. and prompts me to restart but nothing.
If you restart the computer and try pressing and releasing the F8 function key so as to get to the Advanced Startup Menu (normal mode, safe mode, etc.) there should be an option to turn off reboot on error.  Choose that, so that the next normal boot you try, when it blue screens, you can see what the STOP error.

While there were several headline-grabbing ransomware attacks during in 2017, another big threat started appearing at the same time that didn’t get the same coverage – illicit cryptomining.

ok, i was actually able to run repair on the OS from the windows disk.  i get

Root Cause found:
A patch is preventing the system from starting

and it supposedly repaired, i restart and see the windows start up screen, then it goes black, and just sits there (the monitors do NOT go into standby)   i let it sit there for about a half hour or so, no blue screen this time.  

I attempted to reboot in safemode again and once again the last line i see is  at
Loaded: \windows\system32\drivers\crcdisk.sys  and just see "Please wait ..." at the bottom.  whatever is trying to load after crcdisk.sys is what is hanging, but the system repair isn't helping.
I found this page:

A post by McKinlsm:

Found the following on a disscusion board at:

Have been searching the forum for months trying to find a solution to the halting installation, usually thought to have been associated with crcdisk.sys.The problem is in fact caused by pcmcia.sys files! To get round this, you need to delete or rename two files, but this can't be done from the safe mode command prompt, due to permissions.Instead, reboot from the install dvd and go to repair, then command prompt. Locate and rename the following files...Navigate to: c:\windows\system32\drivers\      Rename pcmcia.sys pcmcia.oldNavigate to: c:\windows\system32\driverstore\filerepository\      Rename pcmcia.inf_539d553e pcmcia.inf_539d553eoldTried it on my computer and it worked great, figure you already know this but maybe by chance someone else is looking and this is what they get first

I tried once again to repair the OS with the utility, i got this information which may mean something to you, it doesn't to me.  its interesting that after 3 repairs i'm getting unrepairable stuff.  i'll try that solution in the previous post and return.

also inrelation to your last post, i have renamed the files in \system32\drivers\
but in the \driverstore\fileRepository folder i have pcmcia.inf_1259a379 and pcmcia.inf_78f9157e but not pcmcia.inf_539d553e that your instructions talk about.  should i edit both of them to ....old or just one and if so which  one?
You may have different names if you have different models of pc.  I would suggest trying both of them at first...
vbaccountAuthor Commented:
renamed them both,  still hanging after the crcdisk.sys

running check disk from a Bart CD that i had laying around.... prehaps this  files was in a bad sector (the drive is only 2 months old though)
vbaccountAuthor Commented:
i've got it now booting to a black screen with a movable mouse pointer.   it is unresponsive to a ctl+alt+del or any other input other than moving the mouse.  i get the same thing whether i boot to normally or in safe mode.  any other thoughts?
Found another Previously Answered Question with your current problem, and also the old one of CRCDISK.SYS in safe mode:
Vista starts loading then hangs at black screen
