i have Hp pavilion dv4-1125nr laptop. Few days ago when i tried to turn on my laptop it didn't start and screen with the hp logo then freezed. I running through google, other web sites and they said that i should take apart the hard drive, ram and cmos battery. So I did and then when i tried to turn on, the screen won't start, just black but the fan is working and quick launch button leds are lighting. I realized that caps lock and num lock keys are flashing 3 times and pause and flashing 3 times so on. Then i looked hp site and saw the table of sample blink codes. It says it is module error not functional and i have to check memory. But actually i don't understand that what is a module error? It means like my hard drive or ram not fitted correctly? Sorry for my bad english, but hope u guys understand my case and would give me answer.

It's problem with RAM. Try to reseat the memory module. To reseat the memory module, take the memory module out of the memory slot and then put it back into the slot.

tnx for your reply. I fitted the RAM correctly, now the screens has Hp logo and "Press Esc to enter setup" appears on the bottom left corner but still freezed. I pressed Esc, F8, F9, F10 and if I press several times it beeps. I took my hard drive and when turning on the computer wthout hard drive it enters to setup and i tested my memory and passed. I didn't know what exactly to do and made sure that internal cd/dvd drive is first in the boot order. Can it be my hard drive error?
