I run Windows 7 Home Premium. Last night (I can't determine what the cause of these problems were) I began noticing glitchy behavior. I don't get sound from some applications (BYOND, Firefox/IE, etc) -- certain programs won't load if I'm trying to use them online (BYOND, again) -- Windows Media Player won't properly load -- And finally, the kicker that gave me a clue of what was wrong was an error I got loading Microsoft Word 2003 --
c:\Windows\System32\MSACM32.dll is either not designed to run on Windows or it contains an error. Trying installing the program again using the original installation media or contact your system administrator or the software vendor for support.
As a note, Word _does_ load after this, but it seems to load without Aero active in its interface.
I've gotten a similar error at a different time (I can't remember what I was running) with the ntmarta.dll as well.
I've tried Virus Scanning, ran Malware Bytes, nada. After a tip I found online, I tried the sfc /scannow command on the Command Line, and got the result that's something to the effect of "I can tell there's something wrong, but I can't fix it." It left me a log file I can place if necessary.
I can't figure out what step next to take in trying to fix this problem other than reinstalling Windows itself, which I'd really rather avoid doing. Any ideas?
