My hp dv2210us notebook is giving a strange problem.
When i power on the laptop all the lights glow but nothing comes on the screen. Even the bios doesnt load up. After a few random tries it would somehow start, but now it doesnt start even after 10 times. I have tried reseating the ram, even hdd. If i remove the cmos battery for 5 min, it starts working again. Tried setting the default settings in bios but same problem.
 
someone plz help. Now its just refusing to start. :(

EDIT: somehow it has booted just now.

what could be the problem?

EDIT2: flashed bios to latest version, still the same problem.
 
i have similar problems with my 5-yr old sony vaio. turns out one of the RAM slots is bad/loose... if i press down on the ram slot cover, it boots fine, if i let go , it sometimes hangs after a few min.

i added a second ram chip now it boots all the time, except sometimes only half the ram shows up :)
