Wanted to clarify that I have dug for solutions for weeks including this site. It's likely I missed a solution.
Alright, this has been going on for weeks and I've tried most every possible solution I have found on the internet. It began when I noticed a loud and abrupt screech on my speakers when listening to music on my work PC. It was extremely quick, almost like someone tapped the FFW button on a tape for half a second. As the days progressed I noticed it would often happen with more frequency and even noticed my entire screen would flicker. There are a few YouTube videos of the same issue happening (can't seem to remember the search terms) and the comments section is usually filled with solutions. I'll post what I've tried out of the 30 million solutions I've read and hopefully you guys can further help me out. My PC is home-built about 6 months ago, I do the same work on it about 60-70 hours a weeks and do absolutely no hardware tweaking.
- My first idea was a virus. Malwarebytes found some small spyware, cleared it, problem persisted.
- I assumed the soundcard(on board), added a cheap PCI card. Problem persisted.
- I read that uninstalling Malwarebytes solved the issue for many. Problem persisted.
- I discovered it could be observed through my PC latency. http://img585.imageshack.us/img585/4599/9ig5.png
Each spike is when my audio screeches, the larger spikes usually produce a visual hiccup as well.
- I read that outdated drivers could cause the issue. I installed all new drivers (Video, Audio, MOBO components). Problem persisted.
- I read that incorrect/unused drivers could cause the issue. Installed Autoruns. Disabled drivers one at a time to find a culprit. None found.
- I read that wireless drivers cause the issue. My PC is hardwired into our company firewall and has no wireless adapter.
- ***I read that a poorly installed/removed USB device could cause issues. I noticed my device manager refreshing it self frequently. Installed usbdeview and uninstalled any USB drivers that weren't "stock". My device manager still refreshes constantly. There are no Unknown or yellow devices in my list. (*** May be unrelated, not sure)
- Read to delete various programs from StartUp. I have hardly any programs there and they are all familiar.
- Not attempted: Reformatting - Read that the problem will continue to persist.
So this is where I stand. I really hate the feeling that nobody has figured this out and the issues date back to the release of Windows 7. Thanks for helping!
