Specs: Windows 7, AMD ATHLON ,P320,2.1 G
hp g62 notebook starts up to hp logo screen then shuts down.No beeps noise.Tried battery alone,yhe same shutdown,tried the power cord alone,got the same shutdown,Tried a hard reset as suggested on hp site ,got the same shutdown.I removed the hard drive and optical drive ,on startup the same shutdown.I removed the two memory cards one at a time,changed positions one at a time,and got a shutdown on startup.When I removed the two memory cards the power stayed on but no screen.
With everything installed,when you power up you can here the fan and hard drive ,the hp logo screen pops up,you just have time to push theEsc button and see the message "push Esc to enter start menue" change to "Pause startup " then the computer shuts down"

Could be both memory modules are faulty and need replacing, but it's strange you don't get any beeps. Faulty RAM should cause the system to beep several times or continuously on most computers, though I can't say for sure with HP ones as I avoid them like the plague!

But the fact that it stays on with no RAM installed, and shuts off when the RAM is in place, does logically point to the RAM being faulty.

Have you tried going into BIOS set up? If you can get into BIOS, then check voltages and internal temperature readings there as those might be clues to hardware problems. See how the RAM is listed, is that consistent with what is installed?
If you can get into BIOS then you can also run Memtest86 from a bootable CD and confirm memory issue.
Voltage readings that are more than 10% off the nominal values would mean the power supply needs replacing. High temperatures at cold starting into BIOS set up or rising fast (within seconds or even within a few minutes) would typically mean CPU heat sink is not properly secured. In this case you would need to remove it, clean off thermal compound and reinstall with new thermal compound reapplied it correctly.

You have to be a little bit crazy to keep you from going insane.
