Tried to set it up: no video, no codes, Hard Drive light blinks continuously. I first got it it woul turn on fan woul surge then computer would shut down.  I removed cmos battery and reinstalled it. Now still no vid, monitor tests good. Fan surges every 30-50 sec. computer and fan continue running after surge,

@Danley2 6 years is a long time, the product goes into the obsolete list after 4yrs of purchase, that said, here's a few things we can attempt to fix the issue, however, the description so far points towards a hardware malfunction, I suggest you check with an alternate power cord or another wall outlet.

If nothing works, try the below steps:

• Ensure your device is OFF.
• Unplug all the external devices (If any).
• Disconnect the power from the computer
• Press and hold the power button for about 30 seconds.
• Connect the power supply
• Press the power button to turn on your device.
