Following your replies I've done the following, in an attempt to isolate the problem: (memory #1 - "old" memory, memory #2 - new memory) - Runned memtest on both memories with 0 errors - Booted with both memories... kernel hang - Booted with memory #1 on slot #1 successfully - Booted with memory #1 on slot #2 successfully - Booted with memory #2 on slot #1 successfully - Booted with memory #2 on slot #2 successfully - Booted with both memories on windows successfully For some reason, my kernel hangs if I have 2 GB of RAM installed. And I do have High memory support (4GB), although that doesn't seem relevant. Ideas? :X Thank you all for the quick replies.
