I recently upgraded my system by changing my PSU to a Thermaltake TX775 and my GPU up to a Gigabyte ATI Radeon HD6770 Silent Cell. My motherboarde is a Gigabyte GA-M56S-S3. Ever since the upgrade, a quite clicking sound comes from my PC speaker just before POST. It's something like this:
"click-click, click-click, click-click" for a bout 10 times lasting around 30 seconds. The system then boots and runs all day without any other problems, it's just on startup and restart.
At first I thought it might be an HDD seak issue but having disconnected all drives and reconnected them one at a time, that isn't the issue. Last night, I put the old GPU back in the system and the problem went away. Can any one offer a solution? The driver and software for everything in the PC is up-to-date.
