Hi guys,

I finished my first computer build yesterday and I'm having no problems, well, no serious problems. The computer runs fine but for some reason it lets out a screeching noise for a few seconds then stops. It only tends to happen when the computer is under moderate loading (I'm currently downloading a couple of games) and doesn't occur at any other time, such as when I'm browsing the internet or sitting on the desktop. The sound appears to be coming from around the mother board (gigabyte sk 1155)/ graphics card (sapphire radeon 7970)/ cpu (intel i5) area. It's not a serious problem (I hope!) but it is slightly annoying.

Could someone please tell me what's causing it and if it's a problem or not?
