Windows 7 will not boot after upgrading RAM from 2GB to 4GB

I have a brand new HP laptop, the Elitebook 8730w, it has a dual boot configuration, Windows 7 Professional 32-bit and Windows XP Professional 32-bit.

I upgraded the RAM with another stick of 2GB, Windows 7 freezes on start up, when the Windows logo is up, the Windows XP boot works fine and of course sees 3GB.

I have found other cases, but they are desktops requiring more power to make the RAM more stable. Totally unrelated, I have a felling its Windows 7.

Any help would be greatly appreciated.

It seems that you might be dealing with incompatible RAM sticks.
Try booting only with the 2GB stick to see if it freezes. If it works, it means that the 1GB stick and the 2GB stick are different and incompatible in some aspects.
Double check the specs of each RAM stick and make sure that they meet the specs for your model. I would recommend that you checked in www.crucial.com the specs of the sticks required by your model and compare them to what you have.

Sorry, I should have been more detailed on my question. I have 2Gb in the laptop now, I am trying to upgrade by another 2 GB. Windows XP boot sees 3 GB which is normal. The Windows 7 just freezes on boot up.

if I remove the stick, it boots with no issue on either OS. I checked that site and I seem to have the right type of RAM.

Ok..... try alternating the sticks and run some memory tests on each to make sure that both are good. You can download  memtest+ from http://www.memtest.org ...

I took the liberty of making it the only stick in the laptop and still the Windows 7 partition will not boot, but the XP does. I tried the stick in a different HP laptop and the stick is seen by Windows Vista Pro 32-bit. Both on its own and with the stick that is already in it. I will run the memory test.

I just did a Windows Update, there was one update to install, update KB974431, it was a reliability update for Windows 7. I was going to run the memory test after it installed, but the laptop booted into Windows 7 with no issue with the additional RAM.

The only thing I can think of is that the update fixed the issue, I don't know how but it seems to have, it's the only thing that changed during this whole process.

 Consider it case closed I guess.
