Windows Vista Vista Hangs During Startup

Hello, I have started this thread because I have been experiencing problems with Vista as of about an hour ago. While I was playing a game (StepMania, which I've been playing on this laptop daily since I bought it), my computer randomly locked up, and I had to hard reset. I was not browsing the internet when this occurred, and I was in the final stages of cleaning my computer from a malware attack, and everything seemed to be working fine up until my laptop crashed. I've put the malware cleansing on hold until this is sorted out.

Now, every time I boot Vista, about 30 seconds after the welcome screen appears (even if I haven't typed in my password yet), the computer locks up, and all I can do is hard reset. The mouse can move, but clicking does nothing.

I have Windows 7 installed as a dual boot, and it loads fine; I would really like to get Vista running again, though, as that's what I'm more comfortable with using, and most of my programs are installed on and configured for Vista. I am posting this from my laptop right now, using Windows 7.

I really don't know where to start when it comes to fixing errors with my computer, but I did run CHKDSK and it seemed to perform quite a few more actions than I've normally seen it do. Should I post a log that it created, and if so, where would that log be located?

Thank you for your time.

 

Broni has declared my computer at this point to be malware-free.

Anyway, here's what I've done today to try to fix this problem myself, because it's very important that I get Vista running again for some programs that I need, like Microsoft Office.

1. I tried booting Vista in safe mode, and it worked; I tried ComboFix and OTL, but they didn't fix the booting problem.

2. During my next period at college, I started experiencing bluescreens while booting Vista, and safe mode would no longer boot; it would hang while loading BtHidBus.sys and then restart every time, and it still does. After loading Windows 7 and trying to access the C drive, it said it was corrupted and inaccessible. (however it could still load partially when I attempted to boot Vista, so it was certainly readable to some extent)

3. Later I borrowed a Vista install disk from my friend (my laptop had Vista pre-installed, but it did not come with a CD for Vista), and after booting it from the CD, I tried accessing C with Command Prompt, but it gave me the same "corrupted and unreadable" message. I then ran CHKDSK.exe with write permission. It did quite a few fixes, for about an hour and a half. It said afterwards however, that a log file was unable to be created. (with attribute 50, or at least it said something about some parameter "50 ")

4. I then attempted to run a repair install with the Vista disk, but it said it couldn't repair the system files. After the CHKDSK fix though, I could at least access and copy files from the Command Prompt. I then backed up the last remaining personal files from my C drive to my D drive.

5. After this, I still couldn't boot Vista even in safe mode, and in Windows 7 it still says the C drive is inaccessible, but this time because of "Access denied ", even though I am on the administrator account. However, the files I backed up from C in Command Prompt are still there in the D drive, which is good.

I'm starting to wonder if a clean install of Vista on the HD would be the best thing to do. If there's anything I could at least try though, I'll do whatever could possibly fix this problem without reformatting.
