No beeps, no post just Black Screen
I got this computer a HP pavilion dv2700 with 3gb or memory and SATA hard drive. I reinstalled the OS (vista) using the recovery tool from the options. F11 in this case, It al went good everything installed and I was even inserting user details. I turned my back to it for a couple of minues and then I saw this black screen and the laptop would not react. I turned it off and on and there was no POST and just a plain black screen.
I tried to disassemble it to take dust out before and then I started to reinstall the OS. I probably messed it up right there.
I took everything out, the memory and tried them one-by-one
and turned it on, it gave me 4 beeps. (I guess it was just saying there was no RAM) sometimes after putting everything back again it gave me 2 short beeps. Apart from that just the black screen that tells me the screen is good and there is reaction but There is no post , no BIOS... so I cannot go any further.
What can it be??? Please give me some suggestions.
