Hello mate,

It just depends on what was affected by the software. It's not uncommon for software to break something without affecting system files.

SFC will only check for corrupted or modified system files, and then attempt to repair them by replacing them with an original copy from the component store if it's not also corrupted.

It was a screensaver, and although my A-V reported nothing, it screwed with my OS, and I developed 4 or 5 problems. Aren't corrupted files what causes bugs?

Not always. It could be changes to settings, or just something the software is doing.

I always use this section of the forum to read again, you will need these commands.

Many times it is not corrupt files but incompatibility with other apps.
If you have to anti-virus running, not recommended, M$ version and another may conflict.
Always a good idea to backup your system to an external hard drive, if you install an app and it causes problems, reimage the drive with the backup and we are not needed to help you figure it out.
BSODs are always fun, and axe0 is usually one that can finger (typo intentional) it out.
