I have a video clip of the noise but I am not sure where I can post it and link it. It starts on startup and goes away for a few seconds then kicks back in. I'm not sure if its my mechanical hard drive or a fan. I went into my bios and put it in silent mode, and it made no difference. If anyone can tell me where I can post the clip so you can hear it, please let me know. But it's driving me crazy. I don't think its a fan pc my pc stays cool due to my ac making my room freezing. It's a new pc. Thanks for the help, it's much appreciated.
