Using an Asus a7v133-c for a home entertainment system. It was up and running, but was having issues with video being slow during DVD playback and such. I changed some settings in windows and re-started, then went into BIOS and checked all settings. All I did was enable some settings for CPU fan monitoring and saved. System wouldn't re-boot, so I cleared the BIOS by removing the battery, same result. When I power on I get one long beep, then the system shuts down. I tried a different stick of ram to no avail. Will try a different vid card later. Any ideas on this and/or how to fix it?
