I am trying to upgrade RAM. I purchased the required modules for my system. I have Windows Premium Home Edition 32 bit operating system. HP Computer came with two modules installed 512 MB's each for a total of 1 gig it has four slots and is supposed to support 4 gigs of RAM one GIG per slot, for the 32 bit system. It shows in the BIOS that all 4 are there. But when I try to log on all I get is a blank screen instead of my home page coming up. If I take the first two modules out and replace with the old 512 modules that were pre installed everything works. How can I get it to recognize the first two modules and work? Now it shows that I have 3 GIGS RAM with the two old 512's and two new 1 GIGS installed.
Thanks,
Suzanne
