What could be the probable problem? Take a look inside the heatsink, is it clogged with dust? This way you can find a faulty memory module. The output amperage has to be the same as on the original adapter or higher, but not lower. Save settings and exit the BIOS setup menu. When I press the power button the power light flash 8 times, then nothing. At this point I have absolutely no idea on what to do anymore, what to try, etc. Tried powering down,removing the battery and resetting the CMOS and still nothing. Can you please help me with this. I would check the memory first. When i click the computer to start up, it makes a sound like the harddrive is starting up, then it clicks off and repeats this action..
