memory

I'm currently trying to upgrade my old Sony Vaio VGN-SZ1HP/B to 2GB of RAM. It already had 1GB of Crucial RAM in one of its slots, and one empty. I checked on Crucial.com and it confirms that each bank can hold 1GB of PC2-5300.

The 1GB stick already installed was this, but Crucial's page recommended this... The two are identical from what I can make out, so I just ordered another one of the former. Unfortunately the machine refuses to even POST with both sticks installed.

Slot 1 Slot 2

If I remove the old RAM from Slot 1 and replace it with the new RAM it runs fine. If I leave Slot 1 empty and put RAM (either stick) in Slot 2, it won't POST.

Basically it seems that Slot 2 just isn't working properly.

Does anyone have any ideas on how to solve this problem? Or maybe have any experience with this sort of thing with Sony Vaios?

Thanks for any help!
