The system probably uses some of the ram for the onboard video/on board sound...also known as shared memory. If you go to the BIOS setup..you should be able to see what the total memory is and what shares this memory

I have a hp pavilion a1140n and i cant set up wireless internet in my house what do i do


To have wireless internet you would need a (cable or DSL modem depending upon your ISP. A wireless router (doesn't matter which brand) Also for a desktop computer you will need to buy and install a wireless NIC (network interface card) as desktops almost never come with one, only a hardwired NIC (cabled)

Try using a different monitor to check if it is your monitor that is indeed bad.

Also, try using a different cable if possible.

If the computer is at fault (different monitor didn't work either) then you can try installing a graphics card.

Look inside your computer and see if a slot for a graphics card is there. This will be a single unique slot unliek the others in the system.

The video above shows how to choose and install a video card.

I recommend Newegg.com for purchasing

I want to upgrade the PSU on my HP Pavilion a1140n


Go as "big" as you want -- the GPU will only draw the amperage that it requires -- it's not a mattter of pouring 2 liters of gasoline into a 1 liter container on the floor, while trying to keep the floor dry.

Both ram not detect


More than likely the 2nd slot your trying to use is bad, however before you make that assumption try inserting a stick in the possible bad slot by itself and see if it will post. Let us know :-)
