Hi, I have a similar problem on my laptop (intermittent loud buzzing, stuttering and skipping of sound--most severe with YouTube video but noticeable with anything that streams).
I tried to implement the solution listed as verified on this post. I found what I think is the correct driver and installed it several times, verifying in my Device Manager each time that the latest version of the driver was in place--to no avail. The driver is
Intel ICH9m-E/M SATA AHCI Controller
version 10.6.0.1002
Not sure whether the following two points might also be relevant:
1. I did not uninstall the old driver before my first and perhaps second install of the update--but I did choose to uninstall subsequently through Device Manager.)
2. The jaStor.sys folder is in the System32 folder, which I thought might be wrong because I am running 64-bit Windows--but at that point, I am totally out of my depth/clueless (so please bear with me!).
Any thoughts? Any alternative explanations for this phenomenon? (I am afraid that watching video on the laptop will eventually induce a nervous disorder!)
Thanks
