did you try to enter last known good configuration? low resolution might help but not likely if its just a boot issue or disabling drivers. i'm not sure whether or not there is driver information contained in a boot sector, but i had a similar issue after an update and was able to enter safe mode (so obviously they seem quite different). It seems you have to exhaust your options at this point or go the long route. You may as well enable boot logging as well so that in the future if you have issues and can boot (albeit with issues or crashes) you will have a reference.
i know you said you're getting the black screen and white letter scroll when you try to enter safe mode, but are you getting the blue screen of death if you try to load straight through? I looked on the internet a minute, but all entries have suggested using the command prompt. chkdsk /r and /p have been suggested although R is the more complete (and by far longer) option. fixboot and fixmbr are the other two that again require a command line. the reason check disk is so vital is because if its simply fragmentation or missing headers, windows will find them in the boot sector and fix them. that's the entire idea behind the tool to fix damaged hard disk sectors. if I was you I would go to microsoft.com and search through the windows 7 knowledge base if you want to fix the issue without reformatting or connecting the drive to a computer which has a working copy of windows 7.
In either case, when the computer crashes, you'll want to look for any hexidecimal output like 0x000000; etc. This will help you find the correct entry in microsofts knowledgebase, the error can be produced for varied reasons. Here's a link to a simple entry, and you can go from there.
Read this first, and after insert your installation disc to get to computer repair. You don't have to hit f8. Tell the disc to repair windows when the screen loads and perhaps this will fix your issue. I thought I had said that, here is the link.Microsoft Windows 7 Solution Center Search Results for Unmountable Boot Volume
