Currently im contemplating upgrading my RAM from a kingston 2GB kit to a set of Crucial Ballistix Tracers, 2GB at first, possibly 4GB - worth it do you think? i want a bit more flash in my case so i think it would be ok? Also, i need a bit of help. Currently, every now and again (Id say every 1 out of 5 boots) im getting a BSOD error that says PFN_LIST_CORRUPT, my pc will restart then ill get a second BSOD, restart then my pc boots fine? I heard, i think, its a memory problem? if its RAM, i could hit 2 birds with 1 stone and get the ballistix, or is it a harddrive error? please help! haha.
