I looked up your RAM specs at Gateway, the 4 sticks of new RAM appears compatible with the board and the original sticks. It looks like you want to use the 4 new sticks, not use a mix of the 2 old 1 GB and two of the new 1 GB sticks. One or more of your new RAM sticks may be bad. Have you tried POSTing with 1 of the new sticks? You may want to boot into memtest86+, using a cd to test each new stick.
Thank you for your reply....I sent back the memory, and they tested one of them bad. Also, the tech person said that Intel motherboards are also pretty picky when it comes to generic DIMMs.
I didn't mix up the old/new memory, I merely installed 4x1Gb of the new memory, and it didn't POST. Out they came, and back to the supplier. I am now considering investing in non-generic memory to get this done and out of my hair.
I'm glad you have a fix. If you can get 2x2GB sticks, your life will be easier than using 4x1GB sticks - some boards really do not like all the RAM slots populated. Check the Qualified Vendor List (QVL) at Intel for your specific make and model motherboard. Also, try to find reviews of the RAM you plan to get, e.g., some of the Corsair DDR2 sticks are experiencing lots of problems.
Not a fix yet....but since a 32bit machine can't use more than 3Gb anyway, I'm thinking of just getting some 2x 1Gb and 2x 512mb non-generic for this one......I have Corsair in my main box, no probs at all.
