Hi, my dell dimension 5150 doesn’t kick start properly. I have to unplug the usb at the back for it to kick start. I have tried everything to fix it but no success. Do you have any idea please?

Check whether when press the power button internal LED or fans start function
If No : Check the AC power cord connected properly Check whether Power supply working If yes : Step 01) Remove the all attached complements except keyboard and mouse Try to turn on the PC Step 02) Remove the RAMs and chean the RAM slots, Reinstall RAMs and check whether PC Start to work If you can see any kind of error code, error sound let us know
