i've just started recording some songs recently. teaching myself to use abelton. so i've got this old sansamp bass DI that i've been trying to record my guitar with. it sounds pretty good until about half way through recording a track, i get this loud electical static noise. i made sure everything was grounded, tried a different guitar, cords and still the loud crackle will happen every time. when i record my sampler, it never does that. the same with keyboard. i tried my amp and lined it straight into the mixer, but the same thing will happen. any ideas why this is happening anyone?

audiokid is correct. The noise you describe is when the audio interface loses sync with the computer-usually due to buffer over runs or latency within the computer itself. Increase the sample buffers to 1024 as a place to start. If that works fine then you can through trial and error lower the buffers until drop out. For a helpful tool to measure your computer latency download DPC Latency Checker. It's easily googled.

Latency has many contributing factors. Layout of the mother board, what controller chip (ICH), how the resources are piggybacked, the efficiency of the BIOS, and of course the operating system and how well it is tweaked for audio. Gaming machines are not audio machines even though they are also powerful. Ram can help if that is the bottleneck, otherwise that will just aid in the speed quest.
