Back to the same issues. Had Dell look @ hardware remotely - said all was good. Did system restore. Had a couple sessions with PT - worked OK. Today, loaded a seq file with only the original mp3 song track and my audio drum track. Tons of static and stuttering. Looked at CPU usage - was varying between 39 and 48%. Seems kind of high for one previously recorded audio track.... not sure what tro do now. Closed PT and re-launched it and it locked up my system. I've spent more time the last month trying to get PT to work like it used to than I do actually recording. Any help most appreciated!
