Hi, I recently re-installed windows vista on my vostro 1500 but everytime windows has its first major update I get a brief blue screen after restarting and the computer won't even run in safe mode. It used to go into hardware repair mode and even system restore cannot sort it. I've re-installed Vista over 3 times now using different combinations of drivers and applications installed before Windows update, but always the same thing happens. The laptop is totally fine until the first update (which takes roughly 20 or so minutes to download). What can I do about this? I presume it's a software error not hardware because it was fine before I re-installed Vista (I did it by running from the disc as the boot rather than through windows). Any help would be greatly appreciated because I'm heading back to Uni very soon nad need to get it sorted. Thanks, John.
