Black screen of death

*****HELP*****

 

I've just cleaned out my laptop, taken the base off, cleaned the fans etc. I had to take the battery out and ram but not I can't get it to boot to windows or bios. 

 

Tried hard battery reset and I've checked everything is connected. 

 

Any ideas?

kiss it good by if you spinned the fans with compressed air 

for it makes fan a genarator and will produce more than 12vdc, seen 57vdc just spinnning fan will destroy the fan circuit, when boot it will not see the fan circuit = blank screen

always hold fan from spinning when using compressed air to clean laptop for the plug is fragile , tower can unplug fan

search for another motherboard 

check CMOS button 3v battery is installed correctly .....see the plus side when in socket

Held the fan, I've worked on 100s of laptops without any issue. 

I've taken the base back off. It lights up the keyboard but the fan spins for a couple of seconds and slows and starts again. 

Can't get into bios either. Wondering if I should try flashing it?

the symptoms you desdribed, failed POST (power-on self-test)

not  seeing the CPU fan  then says reboot then try again

check fan speed wire is connected 

re check RAM incertion
