Dell Optiplex 3050 not loading when turned on

Question

When the computer is turned on, it does not load. You don't see anything on screen, not even Dell logo goes on. You have to force turn it off (hold power button) and then try again, then it may turn on or not and you try again. The monitor is working fine, I tested it.

What specific version of the 3050 do you have? The Micro, Tower, Small Form Factor?

Based on your limited description, anything could be suspect.

First thought, reset the BIOS (CMOS Memory). Open the case and with it powered off, remove the CR2032 coin cell battery on the motherboard for at least 10 minutes. Reinstall the battery, observing polarity. Try to power on.

Didn't know there were more than one 3050s. Mine would be The Micro.

Did you do the CMOS reset as I suggested? and if you did what is the outcome?

LinasKan · Answer

Yes I did, didn't help

fireberd · Answer

Sadly, with the symptoms, could be power supply, motherboard, CPU, etc.  However, reseat the 24 pin power connector from the power supply to the motherboard and the front panel connector on the motherboard.  (Reseat-unplug then plug back in).  If that doesn't do it, a trip to a repair shop looks to be in order.

Did you get a solution?

@S8R​  Did you already replace the battery and try a BIOS reset? Next couple of things to try is disconnect the HDD/SSD and turn on.  It should then display 'No boot device found.'  If not... The 3050 may support BIOS recovery.  Be sure to read thoroughly.
