Approximately four days ago, I was rearranging my monitor setup in order to use one monitor for my new mini-pc.
The steps that I took, while the computer was powered on - yes, I know, major ID10T error, were the following:
1 - Removed HDMI Cable from the MSI Radeon 6850's first [left] HDMI port. This monitor was currently configured to be the primary. 2 - Removed DVI Cable from ASUS Mobo's internal video card port 3 - Plugged DVI Cable into Radeon 6580's first [top] DVI port 4 - Crawled out from under the desk to verify that the secondary monitor was now primary and receiving signal. All good. 5 - Satisfied, I loaded up the newest episode of my favorite show while I went to work on my MK802.
While tinkering with the MK802, I noticed that a sudden, half-a-second buzz (Onomatopoeia: BRRRRRRZZZT) had just emitted from my speakers. I thought it was an audio problem with the video at first, and dismissed it as no problem. 5 minutes later, while watching, it buzzed again, with the video signal also going haywire. VLC Media Player was running in full screen, so I chalked it up to just crappy video encoding (hey, how did this one get 9/10 stars? I was asking myself).
The episode ended, and I needed to focus at the task at hand so I turned on Spotify's jazz station. Three minutes later: BRRZTT (note: just a minified buzz-glitch this time). "No!! What is dubstep doing on my beloved jazz station?!" I thought. This was after discovering that Spotify thought that Nickelback was an appropriate artist to play on my Pantera station. Hey, wait a second.. this was the same sound that episode of Big Bang Theory made earlier. Oh noes. Please no. Not a hardware issue!
I powered down my barely 1 year old computer, plugged my monitors back in exactly as they were and turned her back on. One-by-one, I instantiated each of my programs again. Everything seemed to be going fine until I loaded an Mp3 in Windows Media Player as a kind of "controlled variable" test: "BRRRRRRZZZT", my computer grunted unhappily.
Next, I did what every stumped software nerd would do: Googled around for a solution while sporting a disgruntled look with a worrisome feeling in my gut. There appeared to be some kind of Intel driver issue; the recommended solution was to uninstall the Intel drivers completely and rely on your video card only. Thus, I did that. In addition, I turned my iGPU setting in BIOS from "on-board iGPU" to "PCI/PEG". Both monitors are now running from my video card.
The problem is still there. Grrrr.
I decided to go one step further and took my computer to the garage for a thorough cleaning. I reseated both of my RAM sticks and the Radeon 6850 and used the air compressor on a light setting to get all of the dust out.
First boot, post-cleaning, was lightning fast. Awesome. That was kind of unexpected.. maybe the buzz-glitch is gone. I went an hour of watching videos and listening to smooth, tasteful jazz with no issues. Then I booted up League of Legends and to my dismay.. BRRRRRRZZZT.
Now I find myself going to superuser.com to ask for recommendations.
Should I reinstall Windows 7 with my manufacturer's disc? Should I try to run my computer on the internal video adapter and see if the same problem occurs, and if it doesn't, buy a new video card?
Please help :( Many thanks for any insight in advance!
