it seems that it is an issue with the HDD failure and Mother Board.

hope it helps.

try to drain the battery. take out the battery and unplug the adapter. press and hold the power button and count 1 to 10. release hold after 10 secs. do it for 3 times. after that, put battery and adapter back in and monitor.

The Transistor H.O.T maybe shorted , Get a technician to have a check.

It must be the horizontal output transistor, it maybe short circuited. A short in flyback.

make sure that the socket supports your new max Intel.

According to system specs your system is not compatible with the Core 2 Duo or Centrino Core 2 Duo. To upgrade to those chips you would need to replace the motherboard with one capable of running those chips. If you decided to do that you would almost surely need new RAM as newer boards use newer technology. By the time you did this the upgrade would not be cost effective. Hope this helps & please remember to rate my answer. Thanks.

can you hook an external monitor up to it to see what its doing?
