Hi again Raze,
I did test the memory using the built-in memory diagnostics that are incorporated with the new Vista bootloader after I noticed that Windows XP failed to boot. I was able to dual-boot XP fine a couple of days ago, so the RAM must've gone bad very recently. <img src="/ubbthreads/images/graemlins/beyond.gif" alt="" /> was performing poorly on Vista x64 a long time before my discovery and at the time I could still boot into XP. I'm wondering if <img src="/ubbthreads/images/graemlins/beyond.gif" alt="" /> simply doesn't like 4 GB of RAM whether the memory is bad or not.
I will try fiddling with / returning the RAM as you have suggested sometime. I wasn't doing anything out of the ordinary with the RAM at the time it failed. At the moment I'm quite happily playing <img src="/ubbthreads/images/graemlins/beyond.gif" alt="" /> with 2 GB of RAM. <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" />
