i too having similar issues, radio dj not responsive off and on, my pc is a beast, AMD Quad core 4.20 ghz, with 9gb ddr 3 ram, no programs running in background OS win 7 pro, x64 im only running radio dj, xkeys software that controls my programmable keyboard to send short cut keys to the pc, my encoder which is stand alone which i cant mention here, then radio dj, PC CPU use was 7% and only 2.5 gb used of ram and its off and on you click on a song to load it to the slot/deck and it hesitates and doesnt add it and then it will, or I will be loading an event then the event plays we are on air live on my mic, then i am in assist mode i come out of assist mode then it wont play for a minute. I eventually works but is having problems. This just started the last few days off and on.
Also worth mentioning, I cleaned temp files, pc is clean no antivirus software, we dont surf any sites except facebook and or news related sites, nothing gets downloaded to the pc. its just for air play, then also im using maria db for the back end.
Any suggestions? Im about to backup and re-format which is a LONG process to get everything back to the way it was... Im using 3 hard drives too, all SATA one is for the OS, the other 2 are 1TB in a raid for the music and audio... all on the same machine.
Im thinking to go to SSD for the audio for radio dj, then upgrade my ram to 16gb.
Any thoughts???
