it is not a harddrive issue. I said it before that I've ran it without a hard drive inside and get the same result.

I'm going to try to reset it. I have no idea how to swap out the power supply. Thanks for your quick response.

I recently just found it for my grocery store. I assume the installation was done correctly. The sytem starts, records and play for roughly 1 hour. Then a loud beep occurs and system tries to restart but doesn't do so. The lights are on but nothing is on screen. I unplug the power and wait roughly 5 mins and the system would run fine for another 15 mins or so. I tried running the system without a HD and it would still have the same result.
