My Computer is 1 year old . I bought new graphic card (Nvidia Gigabyte GTX970 G1 gaming) 20 days ago and it was working allright, but two days ago I started hearing high pitched noise coming from my PSU. Before I could only hear it sometimes while playing newest games. Now I hear it while browsing google and watching video on youtube. My PSU have 550W. I also noticed on my OC Guru that when voltage reaches 1V this noise start.
So any tips?
