Ok, here are some steps:
First, check the obvious:
** Re-seat the memory chip on your motherboard to make sure it clicks into place properly.
** Check to make sure you have the right type of memory by doing the following:
Use one of the online memory analyzers that have been mentioned:
http://www.memoryx.net/#
http://www.crucial.com/systemscanner/
See if it detects your memory or not. Also see if it suggests the same type/speed.
Another factor is the timings of your memory too. Some memory is more specialized than others. If your existing memory is being used together with your new memory, here are some things to think about:
- ECC and non-ECC memory are not compatible
- memory with different timings (4-4-4-12 and 5-5-5-15 for example) may not work well together, especially if your system is overclocked.
- memory from different manufacturers may not work well together
** if these checks don't raise any concerns, then test each memory chip you have individually to see if the computer can boot up with just one chip. See if it registers in the BIOS and check through Windows as well.
** Run a memory check program like memtest86 while the computer is running just one chip at a time to make sure you have a good stick of RAM.
If your memory passes all of these tests, then most likely the chips you have will not work together in the same pc. See if you can exchange one or both and get a matched pair.

Open your pc......... take out your RAM. look at the label (some have n some don't). Make sure u buy the same ram as write on the label. below is some of RAM type :-
1) SDRAM PC100/PC133 (will be obsolute soon n high price)
2) DDR RAM PC266 and above
3) DDR 2 RAM
If your RAM has 3 portion (the connector part on the RAM leg) it's for sure SDRAM but make sure that u buy the correct PC100 or PC133. most of PC133 will only work on system having a processor of more than 1 Ghz. If your RAM has only 2 portion, it's DDR RAM but u have to make sure if it's DDR or DDR 2 coz both of them has two portion but diffrent portion size and of coz the speed is diff too.
Hope this will help.

Your motherboard might be older and the memory that you are installing might be for a newer CPU. Your best bet might be to buy a new HP Computer. Another issue could be your operating system. Some OS might not recognize the GB etc. Since you did not go indepth with your specs and how old your computer is I am just speculating the problem.

There's no need to find out your motherboard type or peer at labels on your current RAM. As two people have already said, crucial.com do a check on what you have and offer suggestions about upgrades, including the right type.
If your new RAM does fully fit the criteria from crucial, there are two things to consider immediately:
1] Did you take anti-static precautions?
2] Are the chips inserted properly & fully? It would be worth taking 'em out again (remember the static) and reseating them.

Some computer manufacturers as well as motherboard manufacturers have motherboards that only take RAM in same config...ie: using 2 128 chips, 2 512 chips and so on...and the some you can put RAM in like a 128mb and a 512mb chips....I would also check to see if the chip itself is bad...take it to a computer service center and have it tested...some chips are bad when new! Also try to install just the new RAM you bought and see if it is recognized without the orig chip...

i have a second computer/compaq and for some reason it does the same thing, i have 128 and 256 sticks that are correct, yet i can put in 2/128 sticks and it only recognizes 1 of them@128. same wtih the 256, ive tried every variation and finall just put in a 512, as with my gateway and ibm they both accept whatever figure i put in 2/256 and 1 512=1024. still cant figure whats w/ compaq! good luck!!
