This, I'll explain why below.

While that might repair the sectors that could be bad it won't repair files properly. chkdisk (or whatever) can't tell you if a file part is missing, it can't fix "lost data".
Think of it like this, the virus attaches itself to parts of the file in a way that you (might) have to physically remove part of the file. The original file might be like this (binary example):
Now the virus attached itself, giving the file this:
That represents the virus attaching itself to the functions located within the brackets. The brackets represent the virus code as well as the embedded attachment. When you get a BSOD it's generally the result of the virus being embedded too well, causing the AV software to remove file code.
This causes a problem, the original code that the system is looking for is gone and that can cause a KP, or BSOD.
So what do you do? You can run Windows repair, but if your backup files (if any) were also infected and repaired they could be missing code too. The Windows repair on the install disc might be able to use the file on disc (if any) to replace the original with an original copy on the install disc, but that could cause problems later down the road. You could be using a less secure file or even take the chance of re-infection booting the same system (might not be fully clean).
I recommend backing up any data that can not be infected, or at least data types with the least chance of infection (mainly exclude .exe, .msi, anything that "installs" or runs on it's own). Media files, such as mp3 or videos, can be infected but generally aren't and I always keep those and haven't had a problem yet.
After backing up the crucial files then I would recommend doing a format, not because you have to but to make sure you delete everything and don't have the chance of "accidently" running a rogue file.
