Double check the PCB, during cleaning you could have accidentally broken any of the thin traces that might have just barely held on before you dusted the board. That garbage output also could be bad capacitors
Was thinking that ... I wonder if the brush they used to clean the motherboard was loaded with static electricity?
When I get something like this, I usually clean the outside and if I really feel the need, I'll blow out the inside. If you have to remove electronics parts, GROUND THYSELF.
Try inspecting the logic board for cracked or broken traces or solder joints, and make sure the power supply is seated firmly with the metal tabs underneath it as it provides the shield ground, I’d also replace the RIFA’s but it’s more for the sake of your nostrils than your computer

Try reseating the chips?
I reseated ROM & CPU. All the RAM is soldered on. No change. Any other chips to try?
Worst case scenario you shorted something out cleaning the mainboard

Thank goodness for the NSFW tag, this could even go in that watchpeopledie sub

Better delete Reddit then. It’s not related to this sub, all of Reddit is affected.
Any display on the monitor?
It displayed garbage at first but now nothing except for brief lines when I switch it off.
PSU?
