This is one of those "passive" cooled GPU's i bought in 2009. It's served me well, albeit it running hot (65c idle - 85-100c load).

I installed it in a new case, and since then i've been noticing a "buzzing" sound. When I minimize a browser window, or use the scrollbar it buzzes, and i think its also causing interference with my integrated soundcard (realtek).

Under load it buzzes pretty loud, it sounds like electricity is arcing through it (like a tesla coil). im using all the same hardware as i had in the old case.

I'm wondering if maybe its had its better days and I should replace it? I'm selling the PC to my brother and don't want to sell him something that has a bug like this. And definitely dont want to give him something that might fail.

Thinking of replacing it with Newegg.com - HIS H467QR1GH Radeon HD 4670 1GB 128-bit DDR3 PCI Express 2.0 x16 HDCP Ready CrossFireX Support Video Card (dont think i'll do passive cooling again, too much worry).

Last question. If I did end up replacing the video card with a new one, and i still have this buzzing issue, what would be the next thing to troubleshoot to find out whats causing it. (i cant tell whether or not its coming from the videocard or the motherboard right near the videocard, its somewhere in there. but it definitally gets worse when the videocard is under load.)

thanks in advance.

Another detail, when i plug in headphones into the front audio jack, the buzzing is much more noticeable. Too noticeable to even use the front audio.

If the same sound is being heard with two GPU's that pretty much eliminates them as the source. Brand & Model of your Mobo?
You need to be at 650W or better for the 6970 GPU.

its a GIGABYTE GA-EP45-UD3L , bought it at the same time as the GPU. heres the newegg page: Newegg.com - GIGABYTE GA-EP45-UD3L LGA 775 Intel P45 ATX Intel Motherboard

Also, the one i'm going to put in it is a step down on power requirements a 4670 not 6970. My brother isn't planning on doing any serious gaming, just maybe some occasional WoW or L4d.

EDIT: I was playing Allods Online yesterday at medium settings, and even though the GPU temp didn't go over 85c in rivatuner, the video started freezing up and getting choppy after about 6 hours. All the while the ticking arc like sound from the GPU. This is at 1920X1080 on a 23" lcd. anti-aliasing was only set at 2x.
