Having problems with your HP PC Desktops ?

My HP a420n was working fine.To replace the cd-rw drive with a dvd-rw drive I turned the computer off, removed the power cord and replaced the drive (I wore an anti-static wrist band). I then pushed the power button - and nothing happened. No fans moving or noise of any kind. The power is on to everything else (monitor, speakers, Linskys modem & router, etc.)I am now using our old Dell with the Linksys adapter. So I removed the new dvd-rw drive and re-installed the old cd-rw. Still now power. I

Hi,
\015\012
\015\012there is a possibility that you may have pulled off the power switch, to motherboard Connector.
\015\012This will be at the bottom right hand-side of the Motherboard.
\015\012You should have a 2 cable connector for. pwr/sw Power Switch. hdd/led Hard-Drive led. rst/sw reset Switch.
\015\012Check those First. if you didn,t remove the power lead, before attempting any work. you may have arced a current, and damaged the motherboard Or PSU. check the Fuse In The Actual plug lead. to determine the actual power Switch, without a multi-meter. remove the power lead, from the Computer. remove the power/sw connector From motherboard, And Bridge the power/sw with A plastic jumper Block. then replace power lead, and should boot up. If it does the fault is the actual power switch faulty.
