Hello again everyone! I have a computer that SHOULD be running amazingly well, and it does for the most part. I really have NOTHING on here, it is a Dell customized PC, only running 28 processes regularly. Here are the specs: Dell Dimension DIM4600 Pentium 4 CPU 3.00 GhZ 1.00 GB RAM Windows XP Home Edition 2002 So, everything runs fine, I have a wireless Linksys router which I JUST upgraded to the latest firmwire and everything, brand new speakers, an external MyBook 500GB USB Hard Drive which holds my music. Everything was running great, but my music pops and crackles id say about every 10 seconds. I also use a Midi Controller Keyboard (Keystation 61es by M-Audio), I play the M-Tron software and it crackles louder than hell when going on a note for longer than 3 seconds. It is all in and out, on and off. I have no idea what could be causing it, people have told me it is the CPU and the computer is struggling...but it just does not make sense, I am barely running anything on here, my processes are all normal and everything, the Linksys wireless was a hog for a while but the firmwire fixed it up a lot. Does anyone have any ideas or can help me? Also, all of the midi keyboard software is detached from the external HD, the external HD is JUST music, so it has no connection to the popping and crackling of the M-Tron software with the keystation 61es! Thank you for any help anyone can give!
