Having problems with your HP Pavilion m7640n PC Desktop ?

PC wont boot

\015 I bought some ram for this pc. After installing the ram in the pc the pc failed to boot. After installing the old ram back into the pc it still fails to boot. The mother board makes a beeping sound. Indicating that there is a problem with the memory. The pc came stock with 2 GB of PC2 4200. I tried to replace that with Dual channel pc2 4200 ram. I was told before I ordered this ram off of a popular computer parts store. That the new ram would be a drop in replacement. I I remove one stick of Ram the mobo wil not beep. But It will not boot either. When I change the ram around in the dimms it does the same thing in every slot. Even after alternating the ram in the dimms. I put these ram sticks in a friends pc and it accepted the ram and properly identified them. So I know the ram is good. Please help, im ready to stuff a stick of dynamite in this case and blow it all to hell. Thanks in advance!\015

Answers :

Make bios clear
\015\012you have a jumper in your mainboard that do that.
\015\012second make sure you are using the same speed of the ram and that speed do not surpass your computer capability speed. you told that you proved ram in another computer is the same model?
\015\012if not look how much speed they have (bus speed)
\015\012some times the labels in the ram is not apropriate so chek you self in the other computer how is the true speed of new ram taht you take.another problem is that your pc maybe does not support dual channel. any way do what i say to you begining with bios clearing after that put your old ram again to see if is working or not. if yes make sure how is your new ram bus speed ,and if is the samme type so you can tray to put again. write back if problem is solved or not. i can give somme other sugestions
It seems that one of your DIMM slots on your mobo has conked out, sorry pardner but might have to end up changing the entire mobo. Also try out your old RAM sticks on another PC for confirmation.....sodeep
