"New" build is having strange audio and graphics problems - Hardware & Software

I recently upgraded my PC and now had a lot of components left over and decided to build a second semi-gaming capable PC. CPU: Core2Quad Q9550 GPU: Radeon HD 5770 RAM: 2x2GB DDR2 Motherboard: Asus P5QLD PRO PSU: be quiet! Pure Power 530W At first I booted from an old harddrive with Ubuntu already installed. It worked fine until I started XBMC. Whenever the scrolling text at the bottom moved it made weird noises (out of the actual speakers, not onboard or transistors) and the text slowed down and sped up every second or so together with a change in noise. When watching a show it didn't cause any problems as long as only the video was onscreen, but as soon as I paused and the pause menu appeared it made that noise again. After a few minutes in that state it would also produce weird graphics artifacts. I assumed it was a problem with my old Ubuntu install and I got a second harddrive and installed Windows 7 on it. As soon as I had installed the graphics drivers it made the same weird noise anytime the GPU rendered a frame. The higher the framerate the higher pitched the noise became. Scrolling Chrome produced a high pitched noise while some complex pixel shaders with a very low framerate caused only a little beep with every frame. I assumed it might be the PSU (I had my old 700W PSU in there which had already caused problems in my new build) and used the be quiet! instead since 530W should be plenty for a 5770 anyways. I booted both OSs again and had exactly the same problems in both of them. I assumed it might be the mainboard (I used my old P5B SE at first) and used the newer P5QLD PRO instead. The same problems continued exactly as before in both OSs. At this point I thought only the GPU could cause problems like that. So I took the 5770 and replaced the 5870 in my (half) new build with it and everything worked without any problems at all. So the GPU can't be broken either. So in summary: It's not the mainboard. It's not the GPU. It's not the PSU. What's left is: The CPU The RAM The case The harddrives (not really since I used two different ones for the two OSs) The TV I connected the PC to From my knowledge none of them could produce audio and graphics artifacts like what I'm seeing. Any ideas? I do still have 4x1GB DDR2 RAM, a Q6600, a few old 80GB harddrives and another TV if you think replacing any of these parts is even worth a try.

Whatever you're plugging your speakers into probably has poor shielding. Try plugging the speakers into a different port, using different speakers, or using a different sound card. [editline]asf[/editline] Wait, scratch that. You're getting graphical artifacts too. Is your audio and video going through HDMI to a TV? Make sure the cable isn't damaged.

Maybe these are two unrelated problems. [B]Edit:[/B] I tried moving the audio cable around and the noise didn't change at all, so I guess it's not interference. Trying to reproduce those artifacts is still WIP :v:

Alright. I played Saints Row IV for a bit and it works without any graphics problems, but the audio problem still exists. I'm not 100% sure that it actually just creates a very short sound any frame is rendered. I can hear the difference in framerate between looking at the city and the ground/sky. While it's neat that I can hear the framerate, I really wish I could fix this somehow. What I forgot to mention earlier is that the audio problem is not happening when using HDMI, but HDMI is not an option because my TV only has one HDMI input and my PS3 is already using that.

I have no idea what the problem is then :u. You could try replacing the TV, or getting an audio card for your computer.

Try updating drivers for your card
