I was the one that started the thread "Are updates necessary?" Here's where I'm at now. So I just wiped my hard drives completely and reloaded Windows 7. I loaded a new version of Reaper. When I bring in a project from the external drive, it takes a loooooong time to load. But, worse than that, I'm having the exact same problem that I was having before. win7 64bit i7 CPU email@example.comGHz 6GB Ram This thing is 6 years old. The performance meter is at around 20% and I've got cracks and pops and static. I've been dealing with this for a while now so I've done all the optimization techniques and nothing is changing. Someone in another post suggested an IRQ problem. Yes, I do have some IRQ's doing multiple tasks, one actually doing 5. On a side note (this may or may not be related) but my mouse pointer sometimes jumps around like it can't keep up. It only lasted for 10 seconds or so and then is fine. Please help.
