Hi all. Back in june 09 i bought a bundle from overclockers and much more. Here is what i bought

*OVERCLOCKED* Intel Core 2 Quad Q8400 2.66GHz @ 3.20GHz Gigabyte GA-EP45-DS3P Intel P45 Motherboard Kingston HyperX 4GB 8500C5 DDR2 Bundle

Anyhow My mobo had a shortege problem so i sent it back. Overclockers kindly sent me a new EP45-UD3LR which looks slightly diffrent to my first its smaller only has a 4 pin 12v slot instead of 8 im guessing its a newer model. The problem iv been getting is a electrical buzzing noise which sounds like its coming from the graphics card when i browse move windows and use the mouse wheel. Has anyone else had this problem? It never used to do it with my original board. Its driving me mad trying to work out what it is. If anyone thinks they know what might be causing this please post here thanks.
