I have a acer tc-780-acki3 desstop with 7th gen intel core processor 7100 with sgb ddr4 ram and dual monitors. I opened my pc while unplugged to clean off the dust from the fan and the heat sink i carefully disconnected it and proceeded to clean it out then I placed everything back inside carefully closed it up and plugged everything back and powered on the system thats when i noticed my keyboard came on then went off an i took the panel of off and noticed the fan twitched so I unplugged it then plugged it back in after five minutes then it powered up hard drive spinning, fan mouse and keyboard lit up but my monitor said no signal and i notice the backlight to the power button wasnt lit.

    Good afternoon Jerrellakins !

    By default, if the unit was working perfectly prior to the procedure, it is best to disassemble and reassemble it by checking for any damage or bad connection.
