So I was planning on upgrading this old laptop (HP Pavilion zd7000) that I had long ago. It had 1 GB of ram, and I was checking the max supported ram using this command
in cmd, and apparently it can support up to 4gb of ram but on the manual webpage, they say the max is 2GB. So I bought two 1GB 333MHz DDR 200pin SODIMM PC2700 RAMs

Anyway, the memory sticks arrived and I removed both of the 512mb rams from the 2 slots the laptop has, and I installed both 1GB sticks. the laptop was stuck on the load screen of windows 7. I tried booting the laptop with 1 GB ram + one of the old ones, but it didn't even boot at all. it was stuck on a black screen. then I tried each 1GB stick alone and every time on a different slot, and it worked completely fine with only the 1GB. I don't know why it wouldn't boot when both 1GBs sticks were installed. I checked multiple articles before buying the RAMs, and asked few people about it, and those were the only ones compatible with the laptop.
Another thing, the laptop had Windows XP Professional but I upgraded it to Windows 7, could it be a reason why it wouldn't boot? When I upgraded it, few of the drivers didn't install, because they are only available for Windows XP.
Any idea of why I can't install a 2GB ram on it? Is there a fix for this? If the max capacity the laptop can handle is 1GB, then why did that command give me 4GB? Should I downgrade to Windows XP and try with 2GB ram?
Thanks for any help.
