for context: i toke apart the all in one and the cpu fan to clean the dust since it’s been a good 8 months, i toke out the ram sticks out too, everything went back to where it is suppose to be yet when i booted it the screen doesn’t show anything. No logo, nothing. The computer itself IS running, the sound and the fan are both working. No there is no beeping, it’s just an empty screen.
as soon as it didn’t start showing anything i toke it apart again to see if i messed up something, i switched the position of the ram sticks, checked if everything was in place, and i found nothing that was out of their positions.
Any help? The computer was bought in China and i remember something like this happening before when i upgraded my HDD and ram, while swapping the cd rom with a SSD, but force shut down fixed it before...it isn’t working now.
The model i believe is just HP TouchSmart 300, it looks like the 300-1020, but some of the specs aren’t the same, don’t know if any of this is helpful.
