Server Shutdown - Cacti No Longer Working

[Diggit2001]

Hello. I am running Cacti on a Windows 7 box and have had it up and running for several years. Last night we had some storms roll through and we lost power for longer than the UPS's could keep the load up. As a result, my Cacti box shut down. When I boot it up now, the Cacti site is no longer accessible and it appears to be an issue with PHP. When I try to hit the site locally, I get this:

HTTP Error 500.0 - Internal Server Error

C:\php\php-cgi.exe - The FastCGI process exited unexpectedly

Module FastCgiModule

Notification ExecuteRequestHandler

Handler PHP-FastCGI

Error Code 0x000000ff

Requested URL http://localhost:80/cacti/index.php

Physical Path C:\inetpub\wwwroot\cacti\index.php

Logon Method Anonymous

Logon User Anonymous

I get the same error when I try to launch my phpinfo.php file.

Obviously something got corrupt, I'm just not sure how to fix it. Any assistance would be much appreciated.

run chkdsk c: /f ?
php -m have any errors?
anything in windows event logs?

Chkdsk came back fine but I did see a lot of errors in my server App log mentioning php_snmp.dll so for kicks, I commented out that line under extensions in my php.ini file and Cacti started working again. I figured that was probably a pretty important component but everything appears to be working, as far as I can tell. Any idea how to get that extension working again?

The only thing I see now in my server log is one of these about 10 times a minute:

C:\Program Files\MySQL\MySQL Server 5.6\bin\mysqld.exe: The table 'data_source_stats_hourly_cache' is full

Thanks.
