Apologies for opening a second topic, but the guy who is very kindly helping me with the initial problem says he does not know about file restore.
Here is my original topic which is still open and unresolved as yet: http://www.bleepingcomputer.com/forums/topic379459.html/page__view__findpost__p__2133787__fromsearch__1
Basically I have had to install a new Windows Vista on my machine and all my files and settings have been saved in a folder called 'Windows.old'.
Basically I could not boot up my machine without getting a BSOD - whether it's was normally or even in Safe Mode.
The problem began when I got some Malware on my machine and it would not allow me to open files off my second hard drive (which had no OS installed on it) without giving an error message and saying I needed to download Windows something or other to defrag and repair the disk.
Much to my shame, it looked legit...but I quickly realised it wasn't. So I uninstalled the program and then tried to run Combo Fix to clean things up. I've used CF 100s of times before and never had an issue.
Anyway, CF asked if I wanted to update so I did and then it began doing its thing. However, an error message appeared saying there wasn't enough disk space to create a restore point and then it restarted and that's when the BSOD issue started.
The error was STOP: 0x0000007E and then it began a crash dump, which took a few seconds before the machine rebooted.
The way I fixed this was be reinstalling Vista.
I followed some steps on Microsoft about restoring from Windows.old but when I did, the BSOD error reappeared.
Also, the machine is not picking up my second hard disk, where the malware was originally found.
It is an IDE hard drive connected to a SATA MB with a coverter and has worked fine for three years now with no issues.
I'd be very grateful for any help on either problem.
