I am using superspeed cache.
Other computers also use superspeed with no problem.
Also I often got message that this dll not working that dll not working. I often have to reinstall dropbox firefox and office.
I do not set the C drive for late write. Even if it's a problem, it wouldn't be like this. The reason is because drive C contains program and those dll is very rarely rewritten.
The drive D that has late write feature don't have this problem.
I scanned the C and D drive and no bad sector is fine.
Usually programs run just fine before restart. Something happen during restart that mess things up.
