Using Asus P5B mobo
Intel Core 2
2x 1.GB DIMM Kingston ram
The mobo gets powered up as indicated by LED. Power button on the front panel does not response, no on-off lights. CPU and PSU fans do not spin. RAM and CMOS have been reseated. All cables removed and reconnected.
Replaced the power unit with another one, same response. Hope I am not forced to buy a new mobo. Thanks for all help.
I could not attend to this task. Sorry. Though the HP Notebook is slightly more than two years old, it is not of the best quality. Computer heats up quickly and starts creating problems. Have installed an external fan now which helps in lengthening the period before the crashes occurs.
