Yes, you can make the PC start automatically when it receives mains power. Most BIOSes have provision to do that. The exact place in the BIOS and the exact wording of the setting option will vary for different motherboards, but it will be under something like "Power Management" and under a sub-menu "Restore after power failure" or something similar.

BUT, your problem will not be solved with this option. There must be something else wrong. If it was working properly before the cleaning, check all connections again. Pull them out and re-insert them again firmly.
