Im having a problem with windows vista. I just bought a new computer and vista home premium for it and everything works fine i downloaded all the updates up to august 2007 malicious tool remover and for some reason i cant get anymore after this and it keeps downloading this same update about 100 times which is odd but this isnt the big problem. When i leave my computer on and im away from it for about 15 minutes or more i come back to the blue screen of death saying something about memory error then it restarts my vista from the beggining without anything installed and i have to keep repeating this process its very annoying are there any updates im missing and should download? Or is there something critically wrong here? Help would be appreciated thanks!
