Hi all. I have currently got two issues with my computer. One of them is that it is making a weird sound when it loads up an application or a web page. It also sort of stops a song when it is nearly finished and then resumes it after. I find that this error can go away when the power options are on high performance, but even when it is, it still makes this annoying sound on BF 3 and the computer almost jitters for a second or so. Need help soon please! The other issue is that my computer suffers from an "invalid process attachment error" now and again. It usually occurs after I do a disk clean up using CCleaner. What can I do to fix these errors please?
