Memory upgrade problem

I have an hp pavilion a1120n and I am trying the add additional memory to it. I have bought 2-1gb memory (pc3200) twice, each time the computer responds the same way. When I install it, either in addition to the existing memory or without the existing memory, when i turn the computer on, it comes on (ie, the power is still working & the fan kicks on), but does not boot up. When I remove the new memory and put the existing memory back in, it is fine. Help!

    Thanks. I have done that. And the memory is the correct memory (both times). The existing memory that the computer came with has been moved all around each time I tried the new memory and it works fine in all the slots.

    Will try the one new and one old.

    I had some beeps once, but they were in backwards, so switched them and the beeping stopped.

    I tried one new memory and one old memory. It starts to boot then says ntldr is missing and says ctrl+alt+del to restart. Press that, it restarts and goes back to that. Change to both old memory and it is still doing that... Now do not have a functioning computer at all... Suggestions???

    hi do you hear any beeps with your new memory ?

    have you tried one new mem and one old mem does it boot and if it does how much memory does it show in your system ?

    where as ur Mother board will support max 4 gb of ram so there is no problem with the max count

I'm looking to upgrade the RAM in my father-in-law's computer (Compaq Presario SR1500NX desktop). All the "see what ram you need" searches on various websites that sell memory indicate PC2700 is...

This is the memory specs for the SR1500.
Presario SR1500NX Memory Specifications Standard Memory 256 MB (removable) Maximum Memory 2 GB Memory Expansion 2 sockets Memory Comments PC2700 DDR SDRAM DIMMs. CPU Type 2.0GHz AMD Sempron 3000+ Model Comments 333MHz FSB, VIA KM400A Chipset.

The PC2700 refers to the RAM speed, so you can use PC3200 which is faster RAM than PC2700, the PC3200 RAM should be more expensive not cheaper unless this supplier has stock he needs to unload.
You will not get any speed performance with the PC3200 RAM because the motherboard cannot make use of this faster RAM.

What video card can i buy for my computer ? I have a HP Pavilion a1120n . It already has an internal video card , but i want to upgrade . Its a Intel (R) 82915G / GV / 910GL Express Chipset with 128 mb...

I suggest you install an AGP video card that suits your requirements. If you play games that require a powerful graphics card, then I recommend the G Force range of graphics cards. A computer shop can recommend to you a graphics card depending upon what programs you are running on your computer. The games programs usually recommends a graphic card with their games.
Don't forget to disable/turn off the on-board graphics card in the BIOS if you use an external graphics card.

My computer PS and fans turn on immediately but after three seconds they slow way down. No signal is sent to the monitor, or to the keyboard. The CPU fan and CPU do not heat up. Could it be the pwoer...

No, if it would have been it the pc would have stopped completely. Try booting without the hard disk - if it starts try booting from a Linux Live-CD and test the memory. If it doesn't try to boot using another memory .
