You could also try this - hold down the power button for apprrox 5-10 seconds, and see what happens. &nbsp;If nothing, release the power button, and push it again as normal. &nbsp;If still nothing, then perhaps a new power cable, but most likely power supply as suggested by Callandor.

A desktop computer is a personal computer designed for use at a single location due to its size and power requirements, usually by one person. The most common configuration has a case that houses the power supply, motherboard, disk storage (usually one or more hard disk drives and optical disc drives); a keyboard and mouse for input; and computer monitor and printer for output. The case may be oriented horizontally and placed atop a desk or vertically and placed underneath or beside a desk.
