HP Pavilion A520N
WXP Home SP2

Strange problem: The indicator light on PSU blinks rapidly. When I disconnect from MOBO, light stays on green.

PC will not boot up, does nothing except for fast blink on PSU.

No hardware changes. Had cleaned interior, using ESD precautions. PC was acting a little strange prior- no internet connection.

Any ideas? Need more info, let me know. I'm stumped.

Thanks.

Battery on MOBO bad/dead?
