Ram?

I am installing new RAM pc133 on a gateway professional 700mhz celeron it originally came with 64 megs of ram i called gateway and they said I can use any kind of pc133. I put 256 in the computer and nothing came up on the screen. I then tried 2 sticks 128mb each and still the same thing. Then I tried the 64mb that came with the computer mixed with one of the 128's and it worked. I was installing xp home on the computer and it crashed in setup. then I put in just the 64 and xp was running setup fine but as we all know 64mb is no good for xp. May I please get some help.

 

Go to www.crucial.com and look up the correct type of memory for your specific computer, it really sounds like the new memory is not compatible. Crucial should give you the right type and you can cross reference what you have already bought to see if it should work or not
