Laptop Won't Boot

‎01-17-2011 03:22 PM

Hey,

 

My Pavilion dv4 won't boot anymore.  I get the classic black screen and blinking caps/scroll lock.  I have seen the tables for counting the number of blinks, however my keys do not even stop blinking.  I counted to thirty then stopped and it is still blinking now ten minutes later.  The frequency is about 1 blink every 3 seconds.  

 

I have hooked up an external monitor: nothing.

I have reseated the memory modules: nothing.

I have had geek squad and a computer science graduate look at it, they both speculate motherboard failure.

I have not tried individually testing each memory module, but am fixing to do so.

 

Input?

I just tried removing the top most memory module then rebooting and my laptop came back to life!  I switched the modules out to determine if I had a bad module or a bad slot and it worked again.  I then tried the top slot alone and it worked fine.  Perplexed, I tried the remaining module in the top slot.  The laptop then reverted to the old error and now no combination of module/slot is bringing it back to life.  Frustrating.
