leek04 0 Posted November 24, 2013 System worked fine for a year, then froze up. After powering off it will not boot. Power light comes on, you can hear HDD power up, then nothing. No display, No network connection. I sent for RMA and they formatted HDD but could find no problems. DVR then worked for 5 days and back to the same problem. Any suggestions?
