A pc 'having power' doesn't necessarily mean it's working. You hear fans and drives spin up and see LEDs flashing and assume the computer is working but those items are powered separately from the motherboard.

Try another monitor on that computer but I'm thinking that monitor won't display anything either. Likely you have a hardware problem with the computer.

It's likely that the video card or possibly something else became unseated when the tower fell over. Unplug the power cord, open the case, & double check all the connections & cards.

it is a hardware mess. may be the connection to the monitor output inside the cpu went mad. idk im expert in software, but all i know is, the site is of little help of u, i suggest u contact a local mechanic or whatever. it is nearly impossible for us guys to determine the exact area of damage of ur tower without actually seeing it. sorry bro :) nd hey i might be wrong so u can also wait for more answers, coz as i said, m a software geek not hardware. i hope ur cpu gets repaired soon :)

PC fell over onto its side? I'd check very carefully and ensure that everything inside is still securely inserted into is the respective socket(s).

Carefully verify the cpu coolings fan is still attached; that the cpu is still properly seated. That "all" cards etc. are properly inserted. If necessary remove any cards and re-insert - carefully.

Obviously do these internal inspections etc. without "any" power cord attached to the computer; not with the computer powered down locally (its own integral on/off switch/button); but actually remove the main power cord too.

Modern computers (post the AT style boards) are still "hot" inside even when their on/off switch is "off" - if the mains power cord is still attached and the wall a-c outlet actually "on". If removing/inserting/installing "anything" inside a desktop/tower etc. "always" ensure there is absolutely no mains power going in. And with portables - remove the battery!

When you say no signal, do you mean the screen is blank or that it say "no signal" on it?

Always pop back and let us know the outcome - thanks
