Monitor won't come on after cleaning pc

[laura264]

I cleaned my pc with pressurized air today. Now the monitor is showing that it’s on but the screen isn’t coming on. I tried everything Google suggested and can’t figure it out. Thank you for any help you can offer.

remove the memory sticks and graphics card (if a separate one) and use a soft bristled brush to clean the motherboard slots and the circuit boards of all those components.
using your fingers, wipe the contacts on the components as well.
reseat and see how that goes.
check no cables came lose with the air blasts.

Check to make sure that you have the monitor connected to the Display card and not the motherboard.

Thank you both for the replies. I will try to do what you’ve suggested. Here’s a picture of the inside of my pc after cleaning it.

thanks for the pic, but honestly (and without malice ) it’s sort of useless.
one from further out or many close up would be better.

but it does look clean!!! (y)

I think I might of cleaned it too well. Here’s a better pic.

How about answering the post # 2 and # 3.

it certainly looks clean, but yeah, the pictures aren’t helping identify anything outstandingly wrong.
apart from that one lose SATA cable, which looks like it should be going somewhere like a CD unit or drive.

Ok, with everyone’s help, I figured it out. Turns out, because my husband put in another graphics card the solution was to simply plug the monitor into another slot. …Which I have marked clearly for future reference. I’m on the pc now, and it’s working great. Plus, it’s nice and clean. Thank you so much everyone for your help!
